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.

Specs:
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 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.
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.
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.

Very good products no problems thanks for everything 711189
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! 637918

perfect fit 599524
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. 588009

Easiest brake job I ever did! Complete assembly bolted to the trailer in the original position. No fussing around. Connected brake line, bled brakes and was rolling again. With free shipping, I couldn't go wrong. 394802
Review from a similar FreeBack 12 Inch in Trailer Brakes
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. 436057

Review from a similar FreeBack 12 Inch in Trailer Brakes
Purchase these units as part of my trailer overhaul. These bolt on in the original holes without a problem, very easy to install, added new kodiak brake lines and new drums, very pleased thus far with the product. like it's all one easy set up. I was going to buy new brakes and associate parts but after seeing these and the price I chose this route after than busting my knuckles trying to mess with springs and stuff. highly recommend 809207
