  • etrailer
  • Brake Assembly
  • 10 x 2-1/4 Inch Drum
  • LH
  • Free Backing
  • 3500 lbs

Free-backing, driver-side drum brake won't engage when you reverse, even if your actuator is activated. Automotive-grade friction pads and e-coated backing plate are long-lasting. Fits 13", 14", and 15" wheels.


Features:

  • Hydraulic drum brake assembly is designed for use with a surge-type trailer brake actuator
  • Free-backing design lets you back up without engaging the trailer brake, even if the actuator is activated
    • Fall-away brake shoe only anchors on drum 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 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
  • Brake mounting bolts are included
    • Nuts and lock washers (BRKH10BS) sold separately
  • QAI and CSA certified


Specs:

  • Application: most standard hub-and-drum assemblies, including Dexter, Lippert (LCI), and AL-KO
  • Configuration: left hand (driver's side)
  • Dimensions: 10" diameter x 2-1/4" wide
  • Mounting flange bolt pattern: 4 bolt
  • Wheel size: 13", 14", and 15"
  • Axle rating: 3,500 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.


This free-backing hydraulic brake assembly 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.


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.

I replaced the brakes on a 1997 Eagle tri axle boat trailer. I was pretty sure what I wanted but I called just to confirm I was getting the right parts and I'm glad I did. Talked with Chedi and he was very helpful. Shipping was very fast, and all parts fit perfectly. I would recommend etrailer to anyone, pricing was fair and great service. 528873

I'm in the process of mounting them now. I can't say how they work yet, but I will say that it would have been nice to know that they don't come with the mounting nuts or bleeder valves/screws. That information should be listed in BOLD FACED FONT at the top of the description. It's not listed anywhere. 508810

The nuts and lock washers needed to mount the brake assemblies are sold separately as part # BIK-00

Excellent product that replaced 25 year old brakes on a boat trailer at a fraction of the price that local dealers wanted for them. I found all of the parts I needed by searching the site and everything installed very easily. 562004

I have had nothing but problems with the backing plates. I have adjusted them about every time I have taken my boat out. One time my boat trailer locked up both tires going down the road about 35 mph. good thing it wasn't any faster or I would have been in the ditch. I'm going to change back to the Manuel lockout brakes once I can get all new drums and brakes. 672443

Purchased a master cylinder and these free backing brakes to replace the water damaged parts on my 25 year old boat trailer. Even though my original parts were no longer available, the personnel at etrailer helped me find the correct replacement parts. I was ready to make modifications if necessary, but to my surprise, everything was a drop in replacement! I wouldn't hesitate using etrailer again. 407738

I did a total rebuild of my boat trailer. I ordered nearly all of the parts from etrailer. New carpet for the bunks new brakes and backing plates as well as a new brake actuator. New wheel bearings and seals. This trailer is old a 1974 but all of the parts fit I was satisfied with all of the products I received and the timely manner in which they were delivered to my door I am very happy with the fine service I received a t trailer and the help and selecting the right parts thank you very much etrailer. 592909

Review from a similar FreeBack 10 Inch in Accessories and Parts


The order arrived quickly and packaged well. Only problem was that the lower staked in studs couldn't be used. Not enough clearance to get the nuts on after assembly to axle plate. I just knocked the lower studs out and replaced them with the studs & nuts that were on the original assembly. New assemblies look well painted and the brake pads look good. These units were installed on a 1988 boat trailer; replacing the original brakes. I hope I get as much or more life from these brakes as I've gotten from the originals! 480508
