Driver's-side and passenger's-side hydraulic drum brakes feature a single-plunger design. Automotive-grade friction pads and e-coated backing plates are long-lasting. Fit 14", 14", and 15" wheels.


Features:

  • Hydraulic drum brake assemblies are designed for use with a surge-type trailer brake actuator
  • Automotive-grade friction material is molded to brake shoes
    • Pads are fully bonded - not riveted - to shoes for long life and more braking torque
    • Less chance of cracking and crumbling that can lead to mechanical lockup, thanks to tapered edge and circular grinding
  • Periodic manual adjustment required
    • Fine-tooth brake adjustment gears allow for a more precise setting
  • E-coated backing plates resist wear and corrosion
  • Single plunger design
  • Adjuster plugs (included) cover access holes to keep dirt and grime out of the assemblies and off of the shoes
  • Left-hand (driver's-side) brake assembly, right-hand (passenger's-side) brake assembly, and mounting bolts included
    • Nuts and lock washers (BRKH10B) sold separately
  • QAI and CSA certified


Specs:

  • Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
  • Dimensions: 10" diameter x 2-1/4" wide
  • Mounting flange bolt pattern: 4 bolt
  • Wheel size: 14" and 15"
  • Axle rating: 3,500 lbs
  • Limited 1-year warranty


These trailer brake assemblies act as part of your trailer's hydraulic braking system. A hydraulic trailer brake actuator is required for these brakes to function.


Thoroughly Tested for Safety

These brake assemblies meet the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. These brake assemblies underwent extensive testing to measure stopping distances when braking. These brakes have also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.


Automotive-Grade Friction Material

Each shoe on these brake assemblies is lined with automotive-grade friction material for improved stopping performance and longevity. The friction material is fully bonded onto the surface of the brake shoe. This lining is custom-molded for a perfect fit. The edges are tapered to ensure long-lasting performance. This taper, along with the circular grinding that the lining undergoes, helps to prevent cracking and crumbling. This durability helps to prevent mechanical lockup, which can occur when brake shoes are excessively worn or broken.


The friction material is also SAE-N certified, which means that it is an environmentally safe product that complies with California and Washington regulations regarding the composition of brake pads. As a result, this material not only provides high-performance braking that can endure the test of time, but it is also environmentally friendly and safe for use throughout the United States and Canada.

Very grateful these were available, as I couldn’t locate locally. The only problem was the backing plate hardware didn’t match my Eagle boat trailer, ( my original backing plates had captivated nuts ) but very glad to have trailer brakes again Thank you, Ray Wolfbrandt Boyne city, Michigan

This product made a huge difference on my boat trailer. The pressed studs are good and "bad" on my opinion. The set I replaced had a standard nut and bolt to attached the assembly. The studs are great, but forced me to use a wrench instead of impact to tighten the nuts on because there isnt enough clearance on my application for a socket. Installed fairly easy and there is a noticable difference in stopping ability. To be fair, the set a relaxed had no braking material and was simply metal to metal. I would def purchase again if needed. Great customer service as well. I got an email to let me know the product shipped, and something I havent experienced before, I also received an email from someone to let me know the parts were delivered!

Received everything a day before it was due. The trailer is 38 years old and due to your excellent web site I was able to correctly identify the correct part numbers for my trailer. This is the second time I've used etrailer for parts and both times my experience was excellent.

It is just as described and went on perfectly!! I always like getting things that fit right the first time and look to be quality made. The two that were on my trailer were in very bad condition (JUNK), and these solved my problem very easily. Also, they are at a reasonable price. +++++ all the way!! The staff that helped me are fantastic in knowledge of there product and SERVICE! One of the best parts is the Fast shipping! A PLUS Thanks all the way to everyone!



- AKUBRK-35
by:

These brake kits are a great solution instead of trying to piece together an old, rusty set up. I did R & R the new brake shoes just so I can lubricate the backing plate where the shoes ride and I did have to drill a 3/8" hole in each backing plate for the water flush fitting. That's just me. Other than that these were a breeze to install and could very well be installed as-is right out of the box.



- AKUBRK-35
by:

These are reasonably priced and they were easy to install. they work well even when wet. The only thing that would have made them 5 star would have been to have stainless springs like most marine brakes.

Only down side is when used on drop axel they are hard to adjust due to a 8 small notches in the manual adjuster.

  • Difference Between 3,500 lb 10-Inch Hydraulic Trailer Brakes for Boat Trailer
    There is a difference between the two 3,500 lb 10-inch hydraulic brake assemblies you referenced, which is that one has a dacromet coating for better resistance to corrosion. Dacromet is an adhesive coating that gives added protection against corrosion so they are optimal for a boat trailer. - Dacromet Coating: Hydraulic Trailer Brake Kit - Uni-Servo - Dacromet # AKUBRK-35-D - Non-Dacromet: Hydraulic Trailer Brake Kit - Uni-Servo # AKUBRK-35 These are otherwise the same hydraulic...

    I would be happy to help you identify the correct replacement brake assemblies for your 2000 Jayco Eagle 14SO, but unfortunately we do not have a break down of the specific components your trailer uses. What you will need to do is remove one of the hub and drum assemblies from your trailer and measure the inside diameter of the drum, and the inside depth of the drum as shown in the included diagram. For example if your drum measures 10" x 2-1/4" then the Dexter Nev-R-Adjust Electric...

    While I am unable to confirm this 100 percent most Shoerlander trailers with brakes use a surge coupler thus hydraulic brakes.

  • Free Backing Hydraulic Brakes for a 3,500 Lb. Axle
    The Hydraulic Trailer Brake Kit part # AKUBRK-35 (part # AKUBRK-35R + part # AKUBRK-35L) does not have a free backing design. They have a single servo design which means you would need a reverse lockout on your trailer coupler in order to reverse the trailer. Instead, you will want to use the Hydraulic Trailer Brake Kit part # AKFBBRK-35 which does have a free backing design and will allow you to reverse without a reverse lockout.

  • Recommended Replacement Hydraulic Surge Brake Actuator For Drum Brakes on 2020 Jayco 12 tent trailer
    I recommend replacing your entire brake actuator on your 2000 Jayco 12 tent trailer. The Demco Hydraulic Brake Actuator # DM72VR is a bolt on actuator that will mount to your 3" channel like the Atwood 85830. This is the best route to go as it is nearly impossible to find any parts for the Atwood actuator since it has been out of production for so long. The etrailer Hydraulic Trailer Brake Kit # AKUBRK-35 is compatible with the Demco actuator I recommended.
