  • 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

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.

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! 666432

A year later and everything is still working together very well. Thanks again for a great product!

Simple and fit the bill perfectly 865286


Ordered a 10”brake kit and bearings for my boat trailer, it all came in quick and bolted right up. Paula was a big help in getting my order straight for me! Thanks 852291


I haven't had a chance to put them on yet they look ok 845151


As expected, quick delivery 844941


Order this for a boat trailer and fit exactly as original. 844240


had them for about a year still working great 815606


My recent purchase of the pre assembled backing plates with cylinders and shoes were a success. They were fast and easy to install. Thank you. 799375


I am super happy with my replacement of the electric brakes on my camping trailer with this Electric Over Hydraulic Actuator and Hydraulic Brakes. It works SO much better than electric brakes ever did. I feel much safer towing the trailer now. 795430


Cannot believe how friendly Danielle was as she waited for me to find part numbers that I needed. She had my order in that afternoon and I received them the next day. Thanks for helping me complete my project and move onto the next. I will be ordering from you again! 772369


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. 762148


Your service was fantastic. Would recommend your company to everyone! You all answered all of our questions on the products we ordered. Thanks Again! 720842


everything working just great 654346


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. 654188


OUTSTANDING price to value ratio. Perfect match for my 2005 Dorsey Dual Axel trailer for my boat. Great parts for the drum and brake kit and could not be happier with shipping time and speed. 646459


Excellent product at a fair price. The parts arrived quickly, they were well packed and exactly as described on line. 636230


Everything went as it should just installed and was ready to go. Right product first time !! Thanks for the professional service!! 575390


Great price, perfect fit, just what I needed to replace my rusty and frozen originals...installed but not on the road yet...they got here quick. You will need your original nuts. 570026

The nuts and lock washers are available as part # BRKH10B
Mounting Hardware for 10" Brake Assemblies
. Each set includes 8 nuts and 8 lock washers, enough fasteners to mount 2 brake assemblies.
-- Mike L - 09/29/2018



Haven't had a chance to compare the new units to the current sets, but they look the same. Lori B. was a tremendous help with my order. I had not dealt with Etrailer before, but I was impressed. I'll be back! Thanks. 564830


Perfect fit, quality parts. Buying the whole kit was cheaper than buying the actuators from the local marina. 544188

  • 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.

  • 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...

  • What Replacement Brakes do I Need for my Shore Lander Trailer with 10 Drums
    While I am unable to confirm this 100 percent most Shoerlander trailers with brakes use a surge coupler thus hydraulic brakes. For this application the Hydraulic Trailer Brake Kit - Uni-Servo - 10" part # AKUBRK-35 is a great replacement. If for some reason the trailer has electric brakes use the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies part # AKEBRK-35-SA

  • Mounting Flange Bolt Pattern of Etrailer.com Hydraulic Trailer Brake Kit AKUBRK-35
    The etrailer.com Hydraulic Trailer Brake Kit # AKUBRK-35 referenced in your question has a 4 bolt mounting flange pattern, as you mentioned. The mounting hole dimensions are 4 inches diagonally across and 2-7/8 inches left to right. This is the standard 4 bolt pattern for trailer spindles. This hydraulic brake kit is designed for 3,500 pound axles and will fit wheel sizes of 13-15 inches. Both the left hand and right hand assemblies are included.

  • Replacement Hydraulic Brakes for a 2000 Jayco Eagle UDST Pop-Up Camper
    The correct braking assembly for your 2000 Jayco Eagle UDST Pop-Up Camper is most likely the Hydraulic Trailer Brake Kit part # AKUBRK-35 which is 10" x 2-1/4" but if you take a quick measurement of the contact surface inside your drum you should be able to confirm this. The correct hub/drum assembly for your 2000 Jayco Eagle UDST Pop-Up Camper will be a bit more difficult to find because there are a few different options depending on axle capacity. In order to confirm this I would...

  • Recommended Brake Replacements For 2000 Jayco Eagle 12SO
    When replacing brakes on a trailer it is often more cost effective to get the entire assembly than to get the parts piece by piece. I recommend the Hydraulic Trailer Brake Kit - Uni-Servo - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKUBRK-35 for your 2000 Jayco Eagle 12SO. However, if you just want the brake cylinder, I recommend the Replacement Wheel Cylinder for 10" and 12" Hydraulic Brakes - Uni-Servo - Right Hand # AKBRKR-H7-R and left hand # AKBRKR-H7-L. For the shoes,...

  • Replacement Trailer Brakes Compatible with 10" x 1-1/2" Drums
    We do have one option available for you, but the # AKUBRK-35 are not the correct solution for this. You're looking for the Dexter Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3,000 lbs # K23-472-473-00, which are an electric brake assembly designed for 10-1/2" brake drums. These are sold in pairs of a left and right assembly, so you would need two of these for a tandem axle trailer. Since these brakes do not come with mounting hardware, so you'll want to use the...

  • Adding Replacement Hydraulic Drum Brakes to Sundowner Horse Trailer With Dexter P-15 SLR Axle
    The correct replacement brakes are going to depend on what axle capacity your Dexter P-15 SLR is and what type of brakes you need. For example, if your axle is rated for 3,500 lbs, you have a 4-bolt mounting flange and wheels that are 13", 14" or 15" then Hydraulic Trailer Brake Kit # AKUBRK-35 would be a good choice for 10" drums.

  • Replacement Hydraulic Brakes for 3500-lb Axle on Boat Trailer
    It sounds like you're looking for replacement drum brakes for your boat trailer that has 14-inch rims and tires in size ST205/75R14 on its 3500-lb axle. We have both electric and hydraulic drums brake kits for 3500-lb axles and since you referenced a surge coupler # T4339720 I will be happy to recommend appropriate hydraulic brakes. For a cost-effective set of left/right brakes you can use part # AKUBRK-35. You'll need one kit for each axle on the trailer. These 10-inch brakes will work...

    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.

  • For Dual Axle Trailers Does it Matter Which Assembly Goes on Front Axle or Rear Axle?
    No. There won't be a difference in the # AKUBRK-35R from front to back, but there is a difference between the Left and Right Hand assemblies. This particular brake is for the right hand side (passenger) of the trailer. The corresponding brake for the driver's side would be # AKUBRK-35L or you can buy the complete set with # AKUBRK-35. For dual axle trailers you'll need 2 of each assembly as well as 2 sets of mounting hardware (lock washers and nuts) # BRKH10B since these brakes do not come...

  • 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...

  • Compatibility of Hydraulic Brake Assemblies on UPF Axles
    The Hydraulic Trailer Brake Kit - Uni-Servo - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKUBRK-35 will work the same as the Dexter Hydraulic Trailer Brake Kit - Uni-Servo - 10" - Left and Right Hand Assemblies - 3.5K # 23-312-313. The difference is mainly in the name brand. Either assembly will work fine on your tandem UPF axles.

  • Hydraulic Brake Assembly Recommendation for Trailer with 10 inch Diameter Drums
    Yes, the hydraulic brake assembly part # AKUBRK-35L is the correct assembly you need for the left side of the trailer. For a set that includes both sides of the axle what you need is the part # AKUBRK-35. These assemblies are for the standard 10 inch brake assemblies that are found on 3,500 lb axles.

  • Parts Needed to Convert Roadmaster Tow Dolly From Electric Brakes to Surge Brakes
    The electric brakes on the Roadmaster Tow Dolly # RM-2000-1 can be converted to surge brakes if you'd like. You'll need the brake assemblies, actuator, and brake lines. For the brakes I suggest # AKUBRK-35. This includes both the left and right hand side which are specific. The brakes are labeled so you know which is which. Our most popular brake actuator is the Demco # 8605001. This fits a 2 inch hitch ball and has a capacity of 6,000 pounds. For a brake line kit I would...
