Free-backing, driver's-side and passenger's-side brakes won't engage when you reverse, even if your actuator is activated. Automotive-grade friction pads and e-coated backing plates are long-lasting. Fit 14.5" to 16.5" wheels.


Features:

  • Hydraulic drum brake assemblies are designed for use with a surge-type trailer brake actuator
  • Free-backing design lets you back up without engaging the trailer brakes, even if the actuator is activated
    • Fall-away brake shoes only anchor on drums when brakes are engaged as trailer is moving forward
  • 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 and right-hand (passenger's-side) brake assembly included
    • Mounting bolts and hardware (BRKH12) sold separately
  • QAI and CSA certified


Specs:

  • Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
  • 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


Note: Because free-backing brakes are designed to eliminate nearly all friction between the brake shoes and the drum when you are driving in reverse, a trailer breakaway kit will not be effective should your trailer disconnect from your tow vehicle while you are backing up.


Free-Backing Brake Assembly

Free-backing brakes let your trailer move in reverse without the brakes being activated by your surge actuator. These brakes are needed if your actuator does not have a reverse lockout, which is a mechanism that ensures that the actuator does not activate when your rig moves in reverse.


Each of these free-backing hydraulic brake assemblies has a fall-away shoe, which provides full braking when your trailer is moving forward, but supplies only limited friction when the trailer is moving in reverse. During normal forward braking, the fall-away shoe expands to catch your brake drum. When driving in reverse, however, the fall-away shoe's extra spring will overcome the pressure from the brake cylinder. This keeps the leading edge from catching on the drum, so the shoe will not fully pivot into the drum. This exerts a smaller amount of friction, just enough to provide a minimal amount of braking when in reverse.


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.

After calling around to Napa, Koi and 2 other trailer companies and not receiving any help I called etrailer and got in touch with Quinn. I explained what I was needing, and he not only found me the right parts, but he also told me about the house brand which was a cheaper option. Everything showed up in 2 days and fit perfectly.



by:

Brakes arrived quickly and in excellent condition. The description provided by etrailer matched exactly what I needed. Worthy of five stars. Thank you

ETrailer CUSTOMER SERVICE VERY HELPFUL

They installed easily and worked perfectly after some miles I adjusted them and they stop confidently.



by:

12" hydraulic drum brakes arrived protected in a well packaged box. Brakes were just as described and very easy to install. I have no hesitation ordering from etrailer again.



by:

Got the 12" backing plates, have yet to install them. My past experience with Etrailer has been excellent! I am rebuilding a large boat trailer and they have had everything I needed to complete the job with great videos on how to install each component. They are the gold standard for an online business!



by:

The product was very good with minor shipping damage. I believe it would be better to ship in one box per axle instead of four backing plates in one box, that is where the damage came from. Your people were very friendly,& easy to work with. The product was exceptional quality.



by:

Brake parts were awesome quality.Web site was easy to navigate.Shipping was fast. I highly recommend and will do business again!
