Features to know about

Upgrade Old Drums to Real Stopping Power: 12" Dacromet-Plated Disc Brake Kit

If you’re done with the weak, inconsistent feel of drum brakes, this Kodiak kit is a solid upgrade. The 12" slip-on rotors mount over your existing idler hubs and use your wheel bolts to hold everything in place. Designed for 5,200-lb to 6,000-lb axles with a 6 on 5-1/2" bolt pattern, these cast iron disc brakes deliver more braking torque and shorter stopping distances. Each caliper is self-adjusting for smooth, balanced stops at any speed.

Built for Wet or Salty Environments: Dacromet Coating Resists Corrosion

Launching in saltwater or towing through rain can tear up unprotected brakes fast. The Dacromet plating on the rotors, calipers, and brackets gives this kit a 300- to 400-hour salt-spray rating for long-lasting rust resistance. It’s ideal for freshwater or saltwater use and still easy to service—just remove the rotor without replacing the hub.

Runs Cooler and Lasts Longer: Vented Rotors and Low-Drag Calipers

When you’re hauling heavy loads or driving long grades, heat buildup can cause brake fade. Kodiak’s vented cast iron rotors dissipate heat efficiently to prevent damage. The low-drag caliper design retracts the stainless steel piston farther than standard types for a cooler-running brake that stays consistent on repeated stops.

Simple Bolt-On Installation: Heavy-Duty Brackets for 5-Bolt Flanges

This kit makes converting an idler axle to disc brakes straightforward. Each ductile iron mounting bracket is built for 5-bolt brake flanges and features side support that transfers load to the bracket instead of the bolts. Extra embossing around the threads provides a tight, secure fit for guide bolts under heavy braking.

Complete Kit for One Axle: Ready to Mount and Go

Everything you need for one axle is included—two Dacromet-plated rotors, two cast iron calipers, two ductile iron mounting brackets, and four stainless steel caliper bolts. Hydraulic actuator and lines are sold separately but only require a system rated for at least 1,500 psi. With 15" or larger wheels, this setup gives you a cleaner install and stronger braking from the first pull of the lever.

GMC Yukon XL
I used this kit to add surge brakes to my 5200#-axle boat trailer. I bought it a couple months ago and it did not have brakes but really should have. The parts are well made and installed easily once I acquired the bolts I needed that weren't included. The description and pictures are not 100% clear that the mounting bolts to put the brackets on the trailer brake flange are not included. I'm not sure why they don't come with the kit but I ended up getting some 1.25" x 3/8" SS bolts to mount them. While the hat-style rotors are nice from a price and ease of replacement perspective, if your lug bolts don't have extra length, you would be better off getting the integral hub and rotor version. Finding longer lug studs for my 20 year old trailer and removing the old ones was a PITA. Had I known, I would have spent the extra $ for the integrated hub/rotor set. The calipers have bleeding screws on both top and bottom so they can be mounted on either side of the trailer. That's a nice feature as its one less thing to go wrong.
Once installed with new actuator coupler and brake lines, the brakes made a huge difference in towing the boat. The boat alone is 3000# and the trailer and gear probably add another 750 or so. It used to push my Yukon XL around when braking but now it tows smooth and easy.
etrailers was awesome to work with. Good communication via email and simple fast ordering and shipping. I will definitely use them for future trailers get needs.

Bought Kodiak full kit of rotors, calipers, and primary hydraulic actuator from eTrailer for my triple axle boat trailer and perfect result. Competitor was couple dollars cheaper, but couldn't answer simple product questions and squirrely about delivery details, and I don't have patience for that crap. Let's go eTrailer!

Excellent experience all the way around! Fast shipping. Simple installation. Great instructions and videos. Reasonable prices. The best part though is the customer service. I ended up speaking to William B a couple times and he guided me thought ordering exactly the right thing. He had me confirm various measurements on my trailer to ensure I had the correct parts. Actually he helped me discover that the parts I was removing were incorrect so if we had of replaced like for like I would have had problems. Getting this right up front made the installation and final quality what it should be. Thank you eTrailer and thank you William!

Great company! Everything was streamlined and processed very quickly with fast shipping. The website is among one of the best out there.

I definitely recommend etrailer.com and am now a customer for life. Product delivered matched the description 100%.

I bought two pairs of brake kits. One package was very good. The second package must have been returned and resold to me without inspection. It was packaged loose. The springs on the back of the brake pads were damaged. I’m not sure about my repair of the springs. Disappointing!

  • Is There an Exact Replacement For a Tie Down 46250 Brake Caliper or What Option is There
    Finding information on the Tie Down 46250 was not an easy task as it was discontinued awhile back. From what I could find, it looks like the calipers marked 46250 often times have to change the mounting bracket and rotor/hub in addition to the calipers. This means the DeeMaxx Disc Brake Caliper # DE86VR would not be an exact replacement and likely not compatible. Your best option is going to be a full replacement like the Kodiak Disc Brake Kit part # K2R35D if you have a 3,500 lb. axle...

    Hey John! Thanks for getting that information from Load Rite! That helps a lot. We have an option with separate hubs and slip-on rotors like you were looking for, and it won't cost nearly as much as the stainless steel setup. I recommend the Kodiak Disc Brake Kit # K2R526D along with two Dexter Idler Hubs # 8-213-5UC1-EZ. The Kodiak kit includes two 12" Dacromet-coated rotors, calipers, and mounting brackets. With the separate hubs, you'll be able to replace just the rotors when needed. The...

  • Differences Between Combined Hub & Rotor and Separate Hub & Rotor Brakes
    The only real difference between using an integrated hub/rotor combo and a separate hub and rotor combo is that if something happens to the rotor and or hub on the separate hub/rotor, you can just replace the damaged component and not the entire assembly. As long as the idler hub you have on your trailer now has a 6 on 5-1/2" bolt pattern, then I recommend using the Kodiak Disc Brake Kit part # K2R526D. If you already have the calipers and mounting brackets then you can use part # KR12D...

    Hey Charles! I would be happy to help you rebuild your trailer's braking system but I am going to need some specific information like part numbers and/or measurements to find you the right parts. What kind of brakes do you have disc or drum? If you could find part numbers on either the caliper or hubs I can find you some replacement brakes or pads. Are the rusty hubs salvageable?

  • Are There Replacement Brake Pads for the Tie Down Engineering (TDE) 46304 Disc Brake Calipers
    I do have an option for you but we don't offer any replacement brake pads for the Tie Down Engineering (TDE) 46304 Caliper as the company is no longer in business. Therefore, our only option to you would be a full replacement for which I recommend the Kodiak Disc Brake Kit part # K2R35D if you have a 3,500 lb axle or the Kodiak Disc Brake Kit part # K2R526D is you have a 5,200 lb or 6,000 lb axle.

  • Are 4 Bolt and 5 Bolt Trailer Brake Flanges Cross-Compatible for Disc Brakes
    The 4 bolt brake mounting flanges are used on axles up to 3,500 lbs. If the axle is any larger then it will likely use a 5 bolt flange. There is one exception to this which is select 4,400 lb axles. That said, you cannot use 4 bolt brakes with 5 bolt flanges or vice versa. In order to choose the correct disc brake kit you'll need to know the axle capacity. The Kodiak Disc Brake Kit part # K2R526D for example is for 5,200 lb axles. I have attached a full list of options below.

  • Can Idler Hub and Over-The-Hub Rotors Be Used to Convert to Hydraulic Brakes on Camper
    You can certainly use idler hubs with slip on rotors to convert your 5th wheel camper to hydraulic disc brakes from electric drum brakes. As you noted, the benefit of this is being able to replace the rotors more easily down the road. This is nice if you find yourself in a situation where only either the hub or the rotor has been damaged, and only one of the two components need to be replaced. The Kodiak Disc Brake Kit # K2R526D that you referenced is a great choice for your camper. These...

  • Troubleshooting Bleeding Kodiak Disc Brake Assemblies
    I'm glad to hear you have tested the HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness - 1,600 psi # HS381-9067 and found it to be working properly. The Kodiak disc brake calipers like kit # K2R526D have a two piece bleeder valve so if you only adjust the bottom section to attempt bleeding, that is the cause of your frustration.

  • Will Kodiak Disc Brake Kit Replace UFP Brakes On 5,200 Lb Torsion Axle
    The correct Kodiak Disc Brake Kit for a 5,200 lb axle is part # K2R526S for stainless or part # K2R526D for dacroment. In regards to compatibility, the brake mounting flange and spindle size are the only factors we can confirm. I don't foresee any issues but test fitting would be the only way to confirm. There are no exclusions for torsion axle trailers in general.

  • Do Dexter and Kodiak Disc Brake Kits Use Same Mounting Brackets
    The mounting brackets of the Kodiak kit like the # K2R526D and the Dexter kit part # K71-647-648 locate the caliper relative to the hub in a slightly different position as well as use different bolt hole dimensions. Because of this the two kits aren't compatible with each other. The Dexter is much more offset towards the axle than the Kodiak, but that doesn't necessarily mean one is better than the other. Both of these brands do things differently but have a great reputation as being very...

  • How to Prevent Rust on Disc Brake Rotor
    The best thing you can do to help prevent rust on your # K2R526D rotor surface is to clean them before storing the trailer. It is likely you will still get a little surface rust which is a common occurrence and not something to be overly worried about. Once you drive the trailer and hit the brakes a few times the rust will be gone. The only way to completely prevent this would be to upgrade to stainless steel rotors like # KR12S

  • Disc brake Kit For EZ Loader Trailer With 5,300 lb Torsion Axles
    The Kodiak disc brake kit # K2R526D will fit your 2018 EZ loader trailer with a 5,300 lb axle. It uses a 5 bolt brake flange which is standard for axles 5.2K-7K. The slip on rotors will work with virtually any 6 on 5-1/2" idler hub. We generally recommend a hub like the # 8-213-5UC1-EZ to go with it. Your UFP hubs should be very similar to the Dexter brand.

  • Inexpensive Corrosion Resistant Disc Trailer Brakes for Salt Water Use and a Boat Trailer
    The best possible material for saltwater applications is going to be stainless steel but since cost is a factor stainless would not be the way you would want to go. The next best thing is going to be a brake kit with Dacromet finish like # K2R526D. The Dacromet has a 400 to 600 salt spray rating but it is always a good idea to spray them of with fresh water after use in salt water.
