Disc Brakes

An increasing number of trailer owners are switching over to disc brakes, and with good reason. Disc brake calipers have only one moving part, as opposed to the many moving parts you find with drum brakes. This means that with disc brakes there are fewer parts to maintain, fewer parts to get damaged and fewer parts to repair or replace, thus reducing the cost of maintenance.


Performance increases as well. Disc brakes deliver consistent braking even at highway speeds, unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a much shorter stopping distance than drum brakes.


Model 60 Leverlock Trailer Brake Actuator

Titan's complete disc brake kit makes the conversion easy. Designed for single-axle trailers, this kit includes not only the disc brake assemblies themselves - along with all the necessary lines, fittings and mounting hardware - it also contains the Model 60 Leverlock actuator. This hydraulic brake actuator has a higher psi rating for disc brake applications and includes an electric reverse lockout so that you can back up without activating your trailer's brakes. To use the lockout feature, you must have a 5-pole flat, 6-way round or 7-pole wiring harness.


Hydraulic Line Kit

Note: If you intend to run brake lines along the axle of your trailer to install disc brakes - as is often done for boat trailers - you will need 1 additional hose (T4890700 - sold separately) and 1 extra hose clip (T0776400 - sold separately) with bracket (T0776300 - sold separately) to complete the installation.

Had an issue with some missing parts (caliper slider sleeve missing), however etrailer is taking care of that. The parts are all manufactured in China, but everything did fit and work well so far. When it comes to disc brakes on a trailer that is going to be dipping into salt water on a regular basis, it doesn't make sense (to me) to go for the real costly parts when they will need to be replaced again in several years no matter how much rinsing you do when you pull it out of the water. 561842

Installed on a boat trailer and has been working good! In my case other parts were needed in order to use an extended tongue, but found them all at etrailer.com with the help of their excellent customer service team! 567280

I had a lot of issues with a used Boat trailer I Just purchased. The surge break system was totally shot. So I decided to upgrade to disc brakes. The kit arrived in two day, The kit was very complete and easy to understand after viewing the Videos on the site. The one problem I had was I should have ordered the bolt set for the kit. I had planed to use the old bolts but they were a bit to short. After the bolt set arrived the install went very quickly. Tip Use a hand operated Vacuum pump to bleed the brake lines. (They are available at other stores for about $20) Be sure to keep the master cylinder full of fluid. Everything now works great. 503932

If the intended market for this kit is a trailer-maintenance professional, the kit is OK. If the intended market is a DIY boat owner, then some caution is in order. I am the later. I am not a mechanic, or anything close to one. I did complete the installation, and the brakes work perfectly. 141885

Installed in Spring 2011. System is bad because: 1) Design of hydraulic tubing kit is very bad. Kit does not allow for the removal of the brake calipers without disconnecting the hydraulic brake line. To repack the wheel bearings the hard tubing brake lines at the caliper must be removed. Frustrating to have to bleed the brakes each time the wheel bearings need to be repacked. A good kit would contain a rubber brake lines for each caliper so the calipers can be removed without needing to bleed the brakes. 2) Outer race of inner hub bearing is a not a common part. OD is 2.328" which is about 0.040" smaller than a standard, common, easy to find, 1-3/8" bearing. To replace the bearing, you must purchase a 1-3/8" bearing, through away the outer race ($$$) and purchase a hard to find outer race (more $$$$). Lost the use of my boat for 2 weekends while waiting to receive this odd size outer race. WHY NOT MAKE THE HUB FOR A VERY COMMON 1-3/8" BEARING THAT CAN BE FOUND AT ANY PARTS STORE??? What if the bearing fails along the road?!? Leave your boat there for a week while trying to find this odd size race? Strongly suggest that you buy and carry extra bearings and the odd-ball 2.328" OD race if you buy this brake kit. Outer bearing is a common 1-1/16". Seal is a common 1-23/32" seal. 3) Hubs are poor quality. One bearing bore on one of the hubs is oversize by 0.0007". Bearing race spins in hub. Thank goodness for Locktite bearing retainer compound! Hubs are pure junk! Check the fit of the bearing races as soon as you get this kit! 43485

Product shipped super fast. The directions were simple, complete, and easy to follow. Installation was easy and fun, even for a guy with minimal hand tools and NO prior experience working on trailers. They look great, even after a lot of highway driving. Best of all, I am completely blown away at how well these brakes work. They stop my 5000lb boat and trailer very efficiently. I have a lot more confidence towing my boat in heavy traffic now. I would recommend these brakes to ANYONE who tows a heavy trailer. 46734

I have a 1999 Zieman double axle boat trailer. I had issues with the coupler sticking, in turn dragging my trailer brakes. Needless to say, they needed to be replaced. I found this kit after talking to the extremely knowledgeable customer support folks at etrailer.com. A few measurements and part numbers later, I was in business. As always, the order process was pleasant and the parts arrived ahead of expectation. The installation went very smooth. Tandom axle trailer, yet brakes only on the rear. The old drums came off nicely and the new rotors and calipers installed quickly and easily. The instructions show the calipers at the 12:00 o'clock position, so make sure you rotate them to 3:00 and 9:00 respectively. The new steel brake lines were exactly the right size and installed in the same holes/brackets as the old lines. I was able to bleed the brakes by myself on an inclined driveway and a clear hose into a clear container. I just used gravity in my favor. Lastly, I installed a 5-way flat and bought the 7pole to 5pole adapter for my truck. I was very impressed after the first road test. What a difference! These brakes work great and are a quality product. Wouldn't expect anything else from etrailer.com. Be sure to add more bearing grease after the first few pulls. I have bearing buddies which make knowing when to add grease very easy. This is a no-brainer upgrade to older drum based trailers. 43877

I have had this brake package installed on my boat trailer for about a year. The real world, on road performance is very good. The braking power is noticeable but smooth. I gave the product 4 stars (not 5) because the "Made in China" cover that protects the reverse lock-out solenoid is rusting even though my boat and trailer are stored indoors. SUGGESTION: I think the Kit should include or Etrailer.com should suggest the correct 7 prong plug that would include the circuit to supply the reverse lockout. My electric skills are good and I was able to install the correct plug. However if a customer is replacing their entire brake system it would stand to reason they would need all the pieces to complete the install. I'am a returning customer at Etrailer.com and will continue to be. 499541

Hello, Thank you for the opportunity to review this product. Overall I am extremely pleased. The price was a major selling point as this was a total conversion on a 1992 boat trailer. The installation was straight forward with no modifications to the axle needed. Every part fit together as advertised and knowing that help was a phone call away was reassuring. My fishing buddies have all had good words about the fit and finish and how much more modern the trailer looks with the upgrades. Thank you again for the great product and the timely service. 241390

I placed an order for this and was surprised how fast i received it . My experience with this company was great. As for the product. I use a trailer to haul a Utv At a minimum of 3500 miles a year. I purchased this kit for more stopping power. The kit was easy to install and has been a life saver. The stopping distance has decreased significantly . I would recommend this product. 635515

Before ordering a brake kit for boat trailer, I contacted eTrailer to discuss my trailer and the specific kit I would require to complete the addition of adding brakes. Not only were they technical, but also provided updates when my order was delayed. The only negative complaint I have is that the kit didn’t have instructions. It seems like a straight forward job, but instructions are always helpful if you run into a snag. Overall, great experience and would recommend eTrailer to others. 550664

I installed this brake kit on my boat trailer that originally had no brakes. Installation was fairly easy as I installed it by myself except for bleeding the brakes. Keep in mind that this kit has no installation instructions. Any info I needed to install was found by watching online videos. You may need a brake line flaring tool as some of the brake lines were much longer than I needed. The Road test with brakes installed seem to work well. I would recommend this kit. 546153

Worked as advertised. I needed an extra long hose and axle sleeve . They arrived in two days. I have an 18ft Lund. When I stop my truck with the boat, The truck stop the same as without the boat.

The kit arrived in a timely manner. All in packages in good shape, nothing missing or damaged. Installed on trailer with no trouble, I do recommend you watch the video on the web site prior to starting install. To do a good clean job of installation you should beg, borrow or purchase a double flare tool where you can install everything the right length rather than coiling the tubing. Looks good and works fine!! 457182

A delay in shipping my order,that believe was not etrailers fault, once the parts for my brake kit were in they shipped very quick. Only suggestion l have is to mention that when converting brakes from drum style to disk that some minor modifications my be needed. 437141

I received the brake kit later than expected due to an inventory problem. No problem to me. The day I received the kit I dry fitted all the components and they all seem to fit fine. One small adaption to the fender support will be necessary, but other than that all seems to be a go. I am installing this on a master tow dolly to reduce the wear on the tow vehicle. Have purchased many items from etrailer over the years and I am very pleased with there service. Thank You 373474

This was ez install for my boat trailer Complete kit made everything simple from actuator thru connection to the new disc brakes I installed. Still works like expected. I keep it covered when not in use, so a year later, my actuator has zero rust and works 100% like new. Very good product. I read the reviews, and was glad that I followed the positive feedback on this brake actuator. 321648

Overall an excellent kit that I would highly recommend to anyone replacing drums with disc brakes on a trailer. Very well thought out. Just a couple of suggestions not mentioned in the online info. You will need a brake line flaring tool, no kit can exactly match the lengths of brake lines for every trailer. There were also no instructions with the brake caliper mounting kits, the mounting bracket has a slight offset to one direction and you can't tell until completely done if it's on correctly. Lastly, the inner bearing races were not seated completely in the discs. All minor inconveniences that were easily fixed. 201676



- T4843100
by:

Service from etrailer was fast and everything I ordered came. The Titan brake kit with actuator works well. The installation instructions for the brakes is completely wrong. Just use it as a parts guide only. You should only be doing this yourself if you have your mechanical act together so the wrong instructions won't be an issue. I would recommend this kit from etrailer to replace your old drum brakes with. 47473



- T4843100

Instruction were horrid. And wrong. Hoses were for a torsion suspension, not leaf spring type, with three very short hoses. I ended up reusing the old hose, which was twice as long. What was supplied was different than what was listed and shown in the pics. Having said all that, they work as advertised. Very happy with the performance. 28908

I bought a boat in June. Boat and trailer weigh in at about 2,750lbs. Not enough to legally require brakes in my state but heavy enough that I drove out of my way to avoid a particularly steep hill on the way to the river boat ramp. I installed the brakes myself; it took the better part of a Saturday afternoon to do it. Admittedly, the second wheel went a lot faster than the first. The hardest part is running the hydraulic lines. Actually it is the planning stage of where to run them. Make sure you buy or borrow a tubing bender for this part. It would be a lot easier if the boat were off the trailer (if you can put in and dock it for the day that would be great). I've not been running with the brakes for a summer season, on local roads and interstates. Not a problem in the world with them. The stopping power on them is great, almost like the boat is not there. Without them, when you hit the brakes, the trailer would push against the hitch and push the truck forward like a kick in the tail. That goes away with trailer brakes. This project was definitely well worth the investment. 24274

Installed on trailer that was previously drum brakes. Had no significant problems with installing new four wheel Titan Disc Brakes. All parts were in the kit and instructions were clear. They function great and have had no problems. 301817

I have now had the boat 24 foot on three hundred-plus mile trips and several to near by reservoir. Brakes have performed perfectly. Improvement over drum brakes is significant. Would not hesitate to orderuse Titan product from etrailer again. Thanks for following up.

Review from a similar Titan Leverlock Model 60 in Trailer Brakes


I do not recommend purchasing this kit!! First issue was the packaging the parts came in. The heavy calipers and rotors were packed in a box, loose, with the bearings and seal. Bearings and seal were just in a plastic bag. No packing material to keep the heavier parts from damaging them. One of the seals was damaged bad enough that I had to purchase another one locally and install. Second issue was one of the calipers had a casting of "China" in large letters. Only one of the four calipers had this casting. They proudly advertise "Made in America" on the website. Third issue was the fact that several parts were missing in the shipment: The bleeder valves, dust covers for bleeder ports, banjo bolt and block assembly adapter and bolts to mount caliper to adapter plate were all missing. So during shipping, the two ports on all of the calipers, were open to atmosphere, inviting contamination. The pictures on the website clearly show yellow plugs installed in one port and the bleeder valve with cover installed in the other. The banjo bolt assembly is an odd, non automotive size and was impossible to purchase locally. I immediately started trying to call etrailer customer support line. After several days of sitting on hold, each time for about an hour, I finally got through. The agents response was "I will have to contact the manufacturer and get back to you". I asked if they had these parts on the shelf. The response was no, we do not. So if I need spare parts in the future, they will not be able to provide them. I asked how long that would be and they responded with: "hopefully before the end of the day". Two days later I got an email saying simply that " I have contacted the manufacture and I am waiting for them to respond". Another 3 days pass and I finally get another email stating that the parts will be shipped with a delivery date that ended up being 9 days after the initial contact with etrailer agent. So overall, it took a little over 3 weeks from the date of the order to finally get all the parts I purchased. There were no apologies from the agent of any kind, an offer to discount the order or even a credit toward additional purchases. This is a very long ways from "71 Years of Great Customer Support". 410068

Review from a similar Titan Leverlock Model 60 in Trailer Brakes


All 6 boxes of my shipment arrived with no damage. All parts were wrapped and packaged well inside the box. Have not installed kit yet but all the parts appear to be good quality. The staff was very helpful with all of my questions and followed up when with me when they didn't know the answer to one of my questions about the rotor. I'll share that question and answer here. Two of the 4 rotors had a channel ground out of the edge. See Picture. Marti didn't know the answer but contacted her tech department and they informed us that this is how Titan will balance the rotor at the factor. 458391

Review from a similar Titan Leverlock Model 60 in Trailer Brakes


Order was shipped right away and received in less than a week. Complete set. Everything you need except wheel bearing grease and brake fluid. Swapping out the old drums and installing the discs was pretty straight foward. All bearings and hardware included with bearing races pre-installed. I did purchase separately 16 grade 8 mounting bolts rather than re-use mine. Instal took me about 8 hours of labor. I did strugle with the steel brake line instalation. While directions seem simple, it doesn't quite work out that way. Steel tubing needs to be mounted on the trailer frame. In order to transition from the frame to the axel, you need some type of rubber connection since the axel is moving and the frame is not. Tech support confirmed, I need to mount all steel lines to the frame. So after running the 19' line to the frame rail just past my rear axle, the 30" section is about 36" too short to reach the frame rail in front of my front axle. End result, I had to re-use a 48" piece of tubing that I just removed. All in all, I made it work. Hind sight, I would have ordered with the Kodiak flex line kit for $100. Would have made installation a whole lot easier for sure. Installation of brake lines took me about 5 hours with boat on the trailer. Titan actuator and bleeding. First off, directions for bleeding actuator with a 2x4 are rediculous. I quickly found out this is not going to work. Requires a lot of pressure to force closed. What they don't tell you is how difficult it is to pull the actuator back into place. I have a suction device that I use to remove engine oil from the dip stick tube. I simply attached a 1/4" ID clear plastic hose to the bleed valve, gave it a few pumps, cracked the bleed valve and BINGO. Perfect suction. Worked like a dream. Just be sure to be standing at the actuator reseviour to keep it full of fluid. Level drops quickly using this method. I bled each caliper 3 times over 3 day period. I also found the Titan actuator a little difficult to connect to 2" hitch ball. I had to pull forward and backwards a bit to both couple and uncouple hitch in order to lock into place and unlock. Perhaps it will get easier as I get used to it, but is was a little frustrating in comparision to my old actuator. Road Test. I pulled forward and applied brakes in short bursts to get the caliper cylinders to move all the way out to make contact with pads and rotor. After about 3 brake applications, you need to check actuator fluid level. I did this about a dozen times, refilling reseviour 3 times. Also, DO NOT over fill reseviour once you have everything final adjusted. Application pressure will force out fluid thru fill cap. Directions say fill to 3/4 full. Good advice. Overall I am very pleased with both eTrailer and the Titan product. 185272

  • Recommended Kit to Add Disc Brakes to Trailer With 3,500 lb Axles
  • There is a kit available that will give you everything you need, but it is important that you make sure you have a 4-bolt brake mounting flange, your bolt pattern is 5 on 4-1/2 and your spindle is compatible with inner bearing # L68149 (1.378" inner diameter), outer bearing # L44649 (1.063" inner diameter) and grease seal # RG06-050 (1.719" inner diameter). If you are unsure you need to use a digital caliper such as # PTW80157 and measure your spindle where the bearings and seal ride, as...

  • Stainless Steel Trailer Disc Brake Parts Recommendations
  • For stainless steel brake parts the various components will have to be pieced together. You could go with a combination of dacromet and stainless steel parts using # K2HR35DS. With this kit the calipers are stainless and the rotors are dacromet. For stainless rotors and calipers you could use 2 of kit # K1HR35S. This kit comes with the bearings, races, and seal. Kit # K2HR35DS does not but would use 1 bearing kit # BK2-100 per wheel. For a brake line kit you can use # 18SI-BLKIT...

  • Other Parts Needed to Install Titan Disc Brake Kit # T4843100
  • The Titan Disc Brake Kit # T4843100 that you referenced basically comes with everything needed to install it except for hardware to attach the caliper bracket to the brake mounting flange. For that you'd basically just need the Mounting Bolts and Hardware kit part # BRKH10A and you'd be set.

  • Disc Brake Kit Recommendation for Spindle that Measures 1 inch in Diameter
  • What is the diameter of the spindle where the inner bearing rides? If it is also 1 inch we have the Kodiak disc brake kit part # K2HR2D that will fit the spindle. Otherwise if you have a different dimension there we wouldn't have a fit.

  • Availability of the Titan Disc Brake Kit # T4843100 But for a Tandem Axle Trailer
  • The Titan Disc Brake Kit # T4843100 is for a single axle trailer because it only comes with enough brake equipment for one axle. The tandem axle option is kit # T4843200 on our site. This is the exact same kit, just with enough brake line and extra brake kit for a tandem axle setup. I have linked some videos that you can reference as well.

  • Solution for Wanting Version of Titan Disc Brake Kit # T4843100 with 2-5/16 inch Hitch Ball
  • A kit like the Titan Disc Brake Kit and Leverlock Actuator w/ Electric Lockout # T4843100 that you referenced could be made with a 2-5/16 inch ball but it would be much easier to swap out the hitch ball you currently have to a 2 inch ball instead as there isn't a kit already put together like this that has that ball size. If your ball mount has a 1 inch ball hole diameter you'd want the part # 40038 or if instead you have a 1-1/4 inch diameter you'd want the part # A-90.

  • Installation of Surge Brakes on Boat Trailer with Telescoping Tongue
  • In order to install surge brakes on a telescoping tongue extension such as yours you would simply need a longer hose to reach the distance of your trailer tongue. For example, if you were installing the Titan Disc Brake Kit and Leverlock Actuator # T4843100 you would then need to add the Titan Hydraulic Brake Line with Fittings # T0777100 and 7 foot Kodiak Hydraulic Brake Hose # BH-3MFS-7. I've added links to video reviews for you to take a look at as well as a link to a help article...

  • Disc Brake Kit Recommendation for EZ-Loader Trailer w/3700 lb Single Axle
  • Your spindle dimensions are the standard 3,500 lb axle dimensions which is exactly what the Kodiak Disc Brake Kit # K2HR35DKG that you referenced is designed to fit so this kit will fit and work well for you. This kit would work really well for a saltwater/freshwater application. The Dacromet and KodaGuard finish do an excellent job preventing corrosion. The bearings and seals of this kit are sold separately so you'll need the part # RG06-050 for seals and part # L68149 and # L44649 for...

  • Disc Brakes Recommendation For 3500 Lb Boat Trailer
  • The Kodiak disc brake kit you asked about, part # K2R35DS, will fit 3500 pound axles with wheel sizes 14 inches or larger. The 10 inch rotors have a 5 on 4-1/2 bolt pattern. The additional 1/2 inch would mean the wheels would indeed be mounted approximately 1/4 inch further out on each axle. The existing hubs along with the bearings and races would have to be removed. You mentioned that the axle has a 4 bolt flange already welded to it. I have attached a photo of how the brake mounting...

  • Replacement Surge Brake Kit with New Rotors and Calipers for Magic Tilt Trailer with Kodiak Brakes
  • Yes, the Titan Disc Brake Kit # T4843100 will replace your brake setup you have on your Magic Tilt trailer that has a 3,500 lb axle. Replacing everything at once will be your best option too. With everything new you know that you won't be working on your trailer in the near future replacing corroded parts.

  • Differences between Titan Disc Brake Kit # T4843100 and # T4843500
  • The primary difference between the two disc brake systems is the hydraulic actuator. The actuator on the T4843100 features electric reverse lock-out and is rated at 6000 lbs towing, 600 lbs tongue weight. The coupler is designed for 1-7/8, 2 inch or 50 mm trailer balls. The kit is compatible with 14 and 15 inch wheels. The T4843500 uses a manual reverse lock-out lever, and is rated at 7500 lbs, 750 lbs tongue weight. The coupler is designed for 2 inch trailer balls only. The kit is compatible...

  • How To Determine If Disc Brake Kit Will Work For Trailer
  • There are a couple things you will need to know when installing a disc brake kit like part # T4843100, which is designed for 3,500 lb axles. For this kit the inner bearing has 1.378 in inner diameter. The outer bearing has 1.063 inner diameter. The seal inner diameter is 1.719. We need to determine what spindles you have on your trailer so we can select the right hub rotors. To do that you will need to remove the hubs and get the bearings numbers off the bearings.

  • How to Wire a Reverse Lockout Solenoid on a Titan Disc Brake Kit # T4843100
  • On the trailer side of your 5-Way flat plug, you should wire the red wire you mention to the electric reverse lockout function of the actuator on the Titan Trailer Brakes, part # T4843100, that you just installed. You will basically run the red wire from the connector to either of the yellow wires that are coming out of the back of the # T4843100, and then ground the other wire anywhere on the frame of your trailer. Check out the 9 minute mark of the video I attached below to see how...

  • Will Titan Disc Brake Kit # T4843100 Work for Saltwater Use
  • The Titan surge brake actuator part # T4843100 that you referenced would work well for you. It's a disc brake actuator and it's zinc coated as well which means it will fight saltwater corrosion.

  • What To Do When Braking Components Fail Due to Rust
  • The best course of action for you at this time would be to replace all of the braking components. Although you could bandage the broken pieces to get back on the road, it is likely that the other components will soon start to fail which will leave you constantly repairing pieces of the trailer where you could just replace everything at once and not have to worry about it for awhile. For example, if you have ever dealt with a bad wheel bearing on a car and just replaced one side, most of...

  • What Spindle is Compatible with the Titan Disc Brake Kit # T4843100
  • The Titan Disc Brake Kit, # T4843100, is compatible with a # 84 spindle for a 3,500 lb axle. We carry different # 84 spindles for the different style axle tubes. If you can tell me the inner diameter of your axle tube and whether it is a round or square tube axle, then I can make a more specific recommendation on the spindle that will work for you. I have also attached a link to all of the # 84 spindles that are compatible with this Titan Brake Kit for you to check out. A brake mounting...

  • Bearing Buddy and Spindle Grease Seal Set Recommendation for 3,500 Pound Axle Trailer
  • Typically, 3,500 pound axles use an inner bearing # L68149. However, it is a good idea to double check that this is the inner bearing on your trailer. For a trailer that has an inner bearing of L68149 with a 1.980 Bearing Buddy, you will want to use the Spindle Grease Seal Set # BB60002. It looks like you previously ordered the Titan Disc Brake Kit # T4843100. This kit uses the L68149 inner bearing. For these disc brakes with the 1.980 Bearing Buddy, the # BB60002 grease seal set will...

  • Disc Brake Kit for Single Axle on a Tandem Axle Boat Trailer
  • The more brakes you have the less work each has to do. But in terms of weight you would want the braking system to be rated at least as high as the weight of the trailer. Given that your boat weighs under 3,500 pounds the total weight of it and the trailer would not be too much more than that so you should be good to go with a braking system on one axle rated at 3,500 pounds. In order to determine what will fit your trailer I will need to know the inner and outer bearing numbers stamped...

  • Is the Titan Disc Brake Kit and Actuator # T4843100 Compatible with Marine Trailers
  • The Titan Disc Brake Kit and Actuator, # T4843100, is an excellent kit for a marine fresh water trailer. The brakes in this kit are zinc plated to provide superior corrosion resistance and durability. Disc brakes are also a great upgrade to add to a trailer if your trailer currently has drum brakes. Disc brakes have less parts and are easier to maintain. You do not have to purchase the entire brake kit if you just need a new actuator. The actuator can be purchased separately as part...

  • Brake Mounting Flange Recommendation for Fitting a 1-3/4 inch Diameter Axle
  • For a brake mounting flange that fits a 1-3/4 inch diameter axle the part # 4-34 is exactly that. As long as the rest of the axle looks fine and isn't rusting as well this would be exactly what you need. The brake mounting flange needs to be welded on perfectly square and concentric and if it is off just a little bit, this can lead to all kinds of problems with trailer ride, stability, tire, and suspension wear. We strongly recommend that brake flanges be welded on by a professional...
