Driver's-side hydraulic drum brake features a single-plunger design. Automotive-grade friction pads and e-coated backing plate are long-lasting. Fits 14-1/2", 15", 16", and 16-1/2" wheels.


Features:

  • Hydraulic drum brake assembly is 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 gear allows for a more precise setting
  • E-coated backing plate resists wear and corrosion
  • Single plunger design
  • Adjuster plugs (included) cover access holes to keep dirt and grime out of the assembly and off of the shoes
  • Mounting bolts and hardware (BRKH12S) sold separately
  • QAI and CSA certified


Specs:

  • Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
  • Configuration: right hand (passenger's side)
  • Dimensions: 12" diameter x 2" wide
  • Mounting flange bolt pattern: 5 bolt
  • Wheel size: 14-1/2", 15", 16", and 16-1/2"
  • Axle rating: 5,200 lbs, 6,000 lbs, and 7,000 lbs
  • Limited 1-year warranty


This trailer brake assembly acts as part of your trailer's hydraulic braking system. A hydraulic trailer brake actuator is required for this brake to function.


Thoroughly Tested for Safety

This brake assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This brake assembly underwent extensive testing to measure stopping distances when braking. This brake has 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 this brake assembly 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 is my first order with etrailer and it was extremely satisfying. I bought two 12x2 uni-servo hydraulic brake assemblies for my Etchells sailboat trailer. Order arrived two days later, right when they said it would. Website described the parts accurately and made everything quick and easy. I was in fact a little suspicious that everything was too easy. Was I going to be disappointed? Nope, just the opposite. Prices very reasonable; less than just the shoes from O'Reilly (which couldn't confirm the exact part, just the 12x2 dimension. I got free shipping which alone is pretty impressive considering how big and heavier these suckers are. Email confirmations were from real person with phone numbers you can call. This outfit is the Amazon of trailer parts. They're going to destroy the competition with this service.
BTW, if there's any issue with the actual hardware I'll update this review accordingly.

Hi Richard! That it quite the compliment -- Thank you so much! Please DO reach out to us if there is anything we can help with with install or whatever else. How long have you been into sailing? That is something I know very little about.

Good product and description was very informative.
I ordered the part with regular ground shipping and it was to take almost a week to get it. However I received an e mail and they said they were going to expedite my order at no additional charge. I received it in just a couple of days. Little did they know I was waiting on this part to fix my boat trailer just ahead of an up coming poker run. Thank you for the great part and more over thank you for Excellent service.

  • 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...

  • Recommended Replacement Braking Assemblies for an Axletek 12HFB-GG
    Ben, for your Axletek 12HFB-GG you are going to need the etrailer Electric Trailer Brakes # AKEBRK-7-SA to replace your brakes. These brakes are 12" x 2" in diameter, will work with both 5.2k to 7k axles, will work with wheels that are 14-1/2", 15", 16", and 16-1/2", and has a 1 year limited warranty

  • 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.

  • 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.

  • 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.

  • 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...
