  • 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.

Items are of good quality and easy to install. I had to make a small adjustment on the 5 mounting holes on the backing plate to 7/16" in order to use the original bolts since no hardware is supplied with the kit. The best was that all other parts were already assembled and factory set which made installation fast and easy. Also, by using the kit the cost of the job was less expensive then replacing all of the individual parts. This was a win win-win for me. Thank you etrailer.




by:

Parts arrived on the date scheduled, the shipper for some reason couldn't find an address that they had delivered to before, this was not any fault of etrailer.com.
All parts fit exactly as they should have and now hopefully I will not have to fix someone else's neglect again, as shown in some of my pics. But if I do I will use etrailer.com.
Big thanks to Shawn for help above and beyond.

  • Brake Assembly Recommendation for Dexter Axles Rated for 5,000 lbs
    Dexter SLR does not indicate the weight capacity of the axle, but if you have 5.2k rated Dexter axles the assembly part # AKUBRK-7L would be the correct left hand brake assembly. Or if you need both sides you'd want the part # AKUBRK-7 which includes a left hand and a right hand side. These fit the standard Dexter style brake mounting flanges found on 5.2 to 7k rated axles that have a 5 bolt mounting pattern.

  • 12 inch Hydraulic Drum Brake Assembly that Activates in Forward and Reverse
    Yes we do carry brake assemblies that do allow for braking in reverse and forward. The assembly you referenced is a free-backing assembly. Typically people with surge brake setups prefer this style since it allows the trailer to reverse without the brakes locking up. But for a 12 inch assembly that will activate in forward and reverse we have the part # AKUBRK-7R for the right side and # AKUBRK-7L for the left side.

  • Can Electric Brakes Be Added To a M1162A Military Trailer
    I do have an option for you but we do not offer any hubs compatible with this bearing combo. Therefore, the best option without replacing the axle would be to simply replace the braking assemblies. The best way to find the correct braking assemblies would be to measure the inside of the drum where the shoes ride. The Hydraulic Trailer Brake Kit part # AKFBBRK-35 for example measures 10" diameter x 2-1/4" wide or part # AKUBRK-7 which measures 12" diameter x 2" wide. I have attached our...

  • How To Find Correct Replacement Hydraulic Brakes for a ShoreLandr Boat Trailer
    In order to confirm the correct replacement braking assemblies for a trailer you'll need to find the axle capacity. The axle capacity can be found on the axle tag in the center of the beam. The Hydraulic Trailer Brake Kit part # AKUBRK-7 is designed for 5,200 lb - 7,000 lb axles. The other common axle capacity is 3,500 lbs and in which case you'd need the part # AKFBBRK-35.

  • Comparing the Dexter Duo-Servo Brake Kit with the etrailer Uni-Servo Brake Kit
    The Dexter Hydraulic Drum Brake Kit # 23-336-337 that you mentioned are Duo-Servo brakes meaning they deliver the same amount of braking whether you are driving either forward or in reverse. The Hydraulic Trailer Brake Kit # AKUBRK-7 that you referenced are Uni-Servo brakes which means that they will still apply braking when going in reverse, just not as much (about 20% total power) as the Duo-Servo brakes. Unless you plan on doing a lot of backing up with your trailer and you need that...

  • Replacement Brake Assemblies for a 7K Trailer with 12 x 3 inch Brake Assemblies
    If you are just wanting to get new brake assemblies you could use part # AKEBRK-7-SA for 12 x 2 assemblies for electric brakes or part # AKUBRK-7 for hydraulic brakes. These measure 12 x 2 inches so they will fit in the hubs you have now, plus they are rated for up to 7,000 lbs axles like that you have. They also fit a brake mounting flange that has a 5 bolt pattern. Although this will work, I recommend going ahead and replacing your drums as well so that you have an entirely new system...

  • What Hubs/Drums Are Needed With the 12 Inch Hydraulic Trailer Brake Kit AKUBRK-7
    The Hydraulic Trailer Brake Kit part # AKUBRK-7 does not come with the hub/drum nor do any of our braking assemblies. If you will need this as well then I would need to know your axle capacity and bolt pattern. If you have a 5,200 lb axle with 6 on 5-1/2" bolt pattern then most likely you will need the Trailer Hub and Drum Assembly part # AKHD-655-6-EZ-K. There should be an axle tag on the center of the axle which I could then use to confirm the above.

  • Replacement 12" Brakes for Fayette Dayton 9254 W-5 Axle
    To replace your 12" brakes I recommend checking out the 7K TruRyde Electric Trailer Brake Kit # TRU96FR or the 5.2K - 7K Hydraulic Trailer Brake Kit # AKUBRK-7 depending on what kind of braking system you have. You'll also need the Mounting Hardware Kit # BRKH12 to complete your installation. According to my research the Fayette Dayton axles are older and some obsolete so I also recommend comparing the brake mounting flange bolt pattern in the attached photo for our brake assemblies to...

  • Replacement Brake Assembly Recommendation to Replace Dexter 23-342 and 23-343
    We have similar assemblies to the Dexter part# 23-342 and the # 23-343 that your trailer has. For our house etrailer.com brand we have the part # AKFBBRK-7R-D and # AKFBBRK-7L-D which is a 12x2 7k rated brake assembly that would work well for you. These are also dacromet coated which means they will resist corrosion.

  • How To Determine Replacement Hubs And Brakes For Boat Trailer
    Unfortunately, just the outer bearing is not quite enough to figure out what you need for replacement hubs and bearings. For a trailer with that much weight it sounds like you have a tandem trailer. I recommend replacing the bearings and seals on all of the wheels at the same time, even if you are only replacing the brakes on one axle. If you remove the inner and outer bearing and can find the numbers, that will really help. Or you can use digital calipers like part # PTW80157 and take...

  • Which Hydraulic Brakes Fit the Timbren Heavy-Duty Axle-Less Trailer Suspension
    The Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR35HDS02 can be used with hydraulic brakes but they will not work with the Dexter # 23-312-313. The Timbren system is designed to be used with the Dexter Trailer Hub and Drum Assembly # 8-201-9UC3-EZ and has a 5 bolt brake flange configuration. For hydraulic brakes that will fit, I recommend the Hydraulic Trailer Brake - Uni-Servo - 12" # AKUBRK-7R and # AKUBRK-7L. These hydraulic drum brakes are 12" x 2" and also have the same 5...

  • Replacement 12 Inch Brake Assemblies Compatible with Old Warner Trailer Hub/Drums
    You can absolutely use the Dexter 12 inch brake assemblies. If you have electric brakes then the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies # 23-458-459 with your current hubs. You may also want the new mounting hardware # BRKH12. For a more economic option that will work just as well, you may want to consider the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies # AKEBRK-7-SA.

  • Replacement Hydraulic Brakes, Hubs, and Bearing Kit For a 12,000LB VRSA Equipment Trailer
    For the 6,000lb Lippert axles on your VRSA tilt bed trailer you currently have the Hydraulic Trailer Brake Kit # AKUBRK-7. With Hydraulic brakes I recommend replacing the entire assembly to reduce the risk of the wheel cylinders failing down the road. We also have the Free Backing Brake Kit # AKFBBRK-7-D if your braking system uses a manual override these will allow you to reverse without the brakes stopping you. I do recommend inspecting your Hub # AKHD-655-6-EZ-K beforehand to determine...

  • Parts to Convert Electric Brakes to Electric Over Hydraulic Brakes
    Converting from electric brakes to electric over hydraulic brakes will give you the most effective braking setup available. You are going to need a number of different parts, and the HydraStar Electric Over Hydraulic Actuator Kit # HBA-10-252-82 will give you an electric-hydraulic brake actuator, a brake line kit, and breakaway kit. Because you have a triple axle trailer, you are going to need an additional hydraulic line kit # 9579-01. If you are interested in a new brake controller, the...

  • How to Measure for Correct Axle Replacement
    To replace your axle you'll want to measure your hub-face (A) and spring-seat (B) dimensions of your current axle (see attached) and choose one with the same measurements. You also want to make sure the weight ratings match up as well. For example, the Dexter Trailer Axle Beam with E-Z Lube Spindles # 7461121 has 95" hub-face and 80" spring-center measurements. This axle doesn't come with brakes or a hub so you'll either need to transfer ones from your current axle or you would need the...

  • How To Determine What Parts are Needed To Add Hydraulic Surge Brakes to a Tow Dolly
    First you will need to determine the spindle size on your 2002 U-Haul tow dolly to determine the correct Hub/Drum # 84546UC3-EZ. Then you will need to see if there is a Brake Flange # 4-35 to find the right Brake Kit # T4071600-500. And finally select your Actuator # DM72VR and Brake Line Kit # 15SI-BLKIT. If you can provide me with the dimensions of the spindle(see image) along with bolt hole pattern of any brake flange present I can help you find the correct parts.
