Excellent. Great packaging and product. Comes with everything you need except screws for the brackets


I haven’t used it yet but all the parts are correct and it’s everything I need.


Great brake assembly's easy to install. Have had no problems in the year since installing them. It's nice being able to get everything at one place at etrailer.


Even though it took 8 days to ship the item (4 days in the warehouse), less than two states over, the products were packaged well and it seems to be good quality. I will be installing them this afternoon.


Used to replace existing lines. Didn’t need all the parts, have some spares now.


Always great delivery time and items fit perfectly


I had everything I needed to finish the job. You might need several more clips for a longer trailer.


Work perfectly on my one-off trailer bu ild


item is as described and worked perfect ly


Easy installation







easy to install.

  • Do Brake Lines Have to be Equal Length for them to Activate Brake Assemblies Equally
    Hydraulic pressure does not apply more braking to the closer brake lines than the ones further away. The pressure is equal across the entire system at all times so the braking would be equal regardless of one set of brake assemblies having shorter lines than the other.

  • Is the Titan Brake Kit Compatible with Actuator on 1994 EZ Loader Tandem Axle Boat Trailer
    Since the actuator you currently have is compatible with disc brakes, it should work fine with the Titan disc brakes as long as the actuator is in good repair. Make sure the existing actuator has a 1500 psi rating and that the bearing and seal numbers listed for the rotors are compatible with your existing bearings. In order for the kit to work for you, your axle will need the standard 4 bolt mounting flange for the calipers to attach to. You might also need the line kit, part # T4829900...

  • Will Brake Hydraulic Brake Lines Work on 21 Foot Boat Trailer
    Yes, the Titan Hydraulic Brake Lines and Fittings for Single-Axle, Torsion-Axle Trailers # T4829900 will work for your 21 foot boat trailer. Brake lines are not trailer-specific so they will work for you. I've added a link to a video review and install to check out as well of the Titan Hydraulic Brake Lines # T4829900.

  • Fitting Size for Brake Line Connections with Titan Hydraulic Brake Line Kit
    Yes, the fittings for the Titan Hydraulic Brake Lines and Fittings for Single-Axle, Torsion-Axle Trailers # T4829900 are standard brake line fittings designed to fit 3/8" x 24 TPI (threads per inch) just like what you mentioned.

  • How To Measure For The Correct Replacement Brake Line Length
    When looking for a replacement brake line kit, you will want to measure from the port on the back of the actuator to the T-Fitting where the lines split off and go to the separate brakes, which is typically right at the axle. There will be a short flexible line included to go from the back of the actuator to the steel line, which is included with the Titan Hydraulic Brake Lines and Fittings for Single-Axle, Torsion-Axle # T4829900, but I prefer to measure this way as the excess steel line...

  • Brake Lines for Hydraulic Brakes on a Slide Axle Trailer
    What I would do is run regular steel brake line back to the mid point of where the axle can travel like you have said. Then from there use the flexible hose long enough to reach when the axle is in the most forward or most rearward position and long enough for the travel of the suspension. We do not have a kit with all flexible hose but a local auto parts store should have all of the parts needed to fabricate something up. The longest flexible hose we have is # T0980100 at 25 inches.

  • Brake Line Kit that Includes 19 Foot Steel Line for Disc Trailer Brakes on a Boat Trailer
    You could use Titan brake line kit # T4829900 instead. It comes with a 19 foot long steel line. Normally if brakes are only going onto one axle of a tandem axle trailer they go on the front axle, not the back axle. That is likely why so many kits only have a 16 foot line. You get better braking when the brakes are on the forward axle.

  • Is a 1600 psi Brake Actuator too Much for Kodiak 10 Inch Disc Trailer Brakes
    Disc brakes require a higher psi than drum brakes. Usually you will see actuators rated for 1500 or 1600 psi with few exceptions. Going with an actuator rated for 1600 psi will work perfectly fine. A 1000 psi actuator would not be sufficient. The issue with flexible cable is that it can move/change shape when the fluid inside is under pressure and that can have a negative effect on braking. However this is less likely to be an issue on a trailer than it is on a passenger vehicle. If the...

  • Recommended Hydraulic Trailer Brake Lines and Hoses
    For brake lines, we have many sizes and they are either flexible rubber hoses like # HS496-252 or fixed lines like # T4829900. I've linked the page to all the components and kits we carry.

  • Brake Lines and Fittings For Single Axle Boat Trailer.
    Here are a set of brake lines and fittings for a single axle trailer # T4829900. They are 18ft long so it should be plenty of length for your boat trailer. I've included a video for you to check out to help with the install. These Rubber Brake Lines # 18SI-BLKIT would be a bit more resistant to the water since you have a boat trailer. Both are 18ft in length so choose your preference.

  • I Want to Replace All of the Surge Brake Equipment on a 2002 Performance Boat Trailer
    The surge brake equipment of your trailer consists of the brake lines, drum brakes and the brake actuator. To ensure I recommend the correct parts for your trailer I will need a little more information. A brake line kit is pretty universal. For a single axle trailer, I recommend using part # T4829900. This kit comes with all of the lines and fittings you will need to replace everything from the actuator to the brake assemblies. For an actuator, I would need to know what type of actuator...

  • Disc Brake Kit Recommendation for Boat Trailer With 3,500-lb Axles
    If you have the same boat trailer as you did in your previous question, which has 3,500 lb axles and 13 inch wheels, then the only kit that we offer for your trailer is the Titan Disc Brake Kit # T4843300. The thing about this kit is that it comes with a coupler, which you already have, and the hub/rotors that you were not wanting. This kit includes the combination of a few different kits. Since you already have an actuator, the kits that you would need are the Disc Brake Assembly (2...

  • Parts Needed to Convert to Electric Trailer Brakes or Repair Hydraulic Trailer Brakes
    You can switch to electric brakes, but there are several parts you will need. First, you need to take a look at the hole pattern for the brake mounting flange. This is the piece that is welded to the axle that holds the brake assembly. The 7 inch brakes you are looking at have a standard 4 hole mounting pattern. If the existing flange has a different pattern, you will need to have the old flange removed and a new one welded on by a qualified professional with experience working on trailers....

  • Will Disc Brake Kit Work with EZ-Lube Spindle
    Yes, you can use the Disc Brake Kit and Actuator T4843500 on a trailer that has a grease fitting on the end of the spindle (often known as an EZ Lube spindle). You do need to make sure that this kit is compatible with your trailer's axle capacity, brake mounting flange, bearings and grease seal are compatible. The Disc Brake Kit T4843500 is rated for a 3,500 lb axle with a 4-bolt brake mounting flange. It uses inner bearing # L68149, outer bearing # L44649 and grease seals # RG06-050....

  • Parts for Switch Over to Disc Brakes From Dexter Electric Drum Brakes With Neve-R-lube Bearings
    For a 7,000 pound Dexter Never Lube axle with 8 on 6-1/2 inch bolt pattern and 9/16 inch wheel studs you will not be able to go with disc brakes on the existing axle. The Problem you will run into is that the center of the hub on your existing brake drum hubs will not work with the slip over disc. Machining the drum off still would not allow the slip over disc to fit correctly. In this case you will need to go with drum brakes like you already have or special order axles that are outfitted...

  • Recommended Disc Brakes for 3,500 lb Axles
    There is a little bit of information from Kodiak brakes that has some tests that I will link you to separately. We do consider Kodiak to be top-notch and for a 3,500 lb idler hub, I recommend the following braking system: - Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Dacromet and KodaGuard - 3,500 lbs # K2R35DKG These will fit over your hubs so long as they have a 5 on 4-1/2" bolt pattern, which is pretty standard, though I'll link you to a help article to figure out how to determine...

  • Replacement Surge Brake Parts for 2004 5 Starr Boat Trailer
    It sounds like you have a Demco Actuator to me like # DM8104002. We also have one with a 4 inch drop # DM8104311. Both are Hydraulic Brake Actuators that are rated at 12,500lbs.,has a 2-5/16 inch ball, and bear the DA10 model number. I was able to look up your boat trailer and the parts used between packages varied. I can help you pick out Rotors, Lines, Calipers, and Pads if you can provide me with more information about the current items on the trailer. I will need the number of...

  • Recommended Replacement Trailer Brakes, Brake Drums and Hydraulic Coupler for Boat Trailer
    The Timbren Axle-Less suspension system you mentioned is compatible with the brake hub/drum # 8-201-51UC3-EZ and the # T4489500 right hand and # T4489600 left hand free backing brake assemblies. The brake drums are galvanized and the brake assemblies have a Galphorite plating for corrosion protection. The brake drum has a 6 on 5-1/2 inch wheel bolt pattern. It sounds like you're interested in a hydraulic or surge coupler. I'd recommend the Dexter Drop-N-Go Brake Actuator, part # 099-175-00...

  • How To Add Surge Brakes to the Timbren 2,200 Lb Axle-Less Trailer Suspension System
    It sounds like you are referring to surge brakes in which case I do have an option for you to add these to the Timbren Axle-Less Trailer Suspension System part # ASR1THDS03. In order to do this you will need the Demco Hydraulic Brake Kit part # 40716-15 and two of the etrailer Trailer Hub and Drum Assembly part # AKHD-545-35-EZ-K. The rest of the parts you will need are brake lines, the Titan Hydraulic Brake Lines and Fittings part # T4829900 and a surge brake coupler, the Demco Hydraulic...

  • Parts Needed to Convert from Drum to Disc Brakes on My Saltwater Trailer
    Your outer bearing # LM67048 will have the same 1.250" inner diameter of the # 15123. So the Kodiak Disc Brake Kit # K2HR526DKG will fit the spindle on your axle without issue. I will say that you should check the bolt pattern on the back of your current brakes to make sure you have a 5 bolt, however. I included a picture of how it should measure as well. As to the actuator, this will depend on if you were looking to go with a surge style actuator or electric over hydraulic. If you are...

  • Hydraulic Drum Trailer Brakes for 2,000 lb Timbren Axle-Less System
    There are hydraulic drum brakes you can use with the 2,000 lb Timbren Axle-Less Trailer Suspension System # ASR2000S02, you'll just need to get a hub and drum that fits (there are no electric disc brakes available). The correct hub and drum for this Timbren system is the Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K. You will then be able to use the Hydraulic Trailer Brake Kit # AKUBRK-35 with Mounting Hardware # BRKH10B. With this you are also going to need a hydraulic drum brake...

  • 3,500 lbs. Axle with Hydraulic Drum Brakes Kit
    I have a solution for you but unfortunately we do not carry any axles that come with hydraulic brakes. What you will need to do is buy the parts separately, but I have all the parts you will need. First, for an axle, you will need the Dexter Axle Beam with EZ Lube Spindles # T3584F-EZ-8974. This axle is 89" long with a weight capacity of 3,500 lbs. which is the same as the # e43SR Axle you were looking at. For your Hydraulic Trailer Brake Assemblies you will want the etrailer Left Hand...

  • Parts Needed To Install Brakes On Haulmark 8 Foot V Nose Trailer
    I did some research and it looks like most Haulmark trailers like yours have a 3,500-lb single axle. If you have different axles then let me know and I can make the correct recommendation.  Your axle must have brake mounting flanges attached behind the existing hub assembly on each side for brakes. If there are no brake mounting flanges then you will either have to replace your axle or purchase brake mounting flanges that can be welded to your axle by a qualified welder.  A common setup...
