Marine-grade, free-backing hydraulic drum brakes won't engage in reverse, even if your actuator is activated. Automotive-grade friction pads are long-lasting. Dacromet-coated backing plates resist rust. Fit 14-1/2" to 16-1/2" wheels.

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 helpful staff. I did all 4 breaks and bearings complete. Glad I checked things out, seals were gone and one wheel had bearings that failed and I was lucky I made it home. Also put on new brake lines and master cylinder, all good now. Tnks
Wayne - 03/03/2022Purchase 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
After the old backing plate was removed from my 20 year old boat trailer, the installation of the new backing plate and break assemble took less then one hour . The drum with the bearings installed slid right on .
Looks like well put together. But when the package came it was open. I also seen where they reduced the price
I Purchased hydraulic drum Brakes - Uni-servo backing plates form Lisa D at etrailer. I could not be more pleased. The items arrived when they were supposed to and were exactly what they were supposed to be. Lisa was very professional and knowledgeable, and followed up through email. I needed the items fast, and even after priority shipping, the cost was less than i could have found elsewhere. I will use etrailer again should the need arise.
Jeff B - 04/16/2018Great on phone help….. OK was very impressed that the 2 ladies I talked with on 2 different calls really knew their STUFF. Very impressed and ordered on Sat. del. on Wed. with tracking sent to me. Will be back when I break these in with new salt water.
Just one of the many satisfied customers with the company etrailer. I have used this on line site to refurbish my used boat trailers over the last 10 + years. During this pandemic I sort of let my trailer sit around and just wait until the end is near to react and make the trailer road worthy. After 3 years in out of salt water (mostly in) you might get this. After acquiring new brakes and drums from etrailer it’s back to the salt water again. Thanks for the essential workers at etrailer George, Savanna, and Carol. Cheers
Good quality parts and materials and/or coatings that will resist the salt water corrosion. Easy swap in for the old parts. I was replacing a set where one brake pad was cracked (the new ones are bonded instead of riveted) and one where the hydraulic cylinder had blown out and drenched everything in brake fluid. Well worth the cost and well worth the additional cost for corrosion resistance if you launch in salt water.
First time order with etrailer.com and can't say enough about the experience. The website is top-notch, from excellent product description video presentations, easy order process and even visuals to provide shipping progress. Excellent assistance on product application and great follow-up customer service. Will not hesitate to order from etrailer in the future. Brakes are excellent quality and build and perfect fit.
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.
The crew over etrailers work their butt off I ordered the wrong 12 inch backing plate with shoes it was already loaded on the truck they went out and pulled it from the truck and did not charge me and reordered and sent the right product it a ride fast
all is good
I was initially concerned about finding the right parts as the trailer was fairly old. etrailer had just what I needed. The website is so elegant. I was able to find the right parts quickly and with comparative options to make a final selection. The how-to videos are great. This made installation a little more comfortable. Especially when you do not perform this type of work every day. The parts were of high quality and are working as expected. I highly recommend etrailer for any of your trailer needs.
Thank you, They came quit and are just the ones I need.
Bent pins on one assembly and had to be removed to straighten before installation. Seems to have been dropped some time during shipping or handling.
They have been working great since inst all.
I received some great advice and help from Leeza in selecting the correct product for my needs. Without serial numbers or identifiable model numbers on my existing trailer parts, she was able to determine the correct parts for my particular trailer needs (on a 25 year old trailer.whose manufacturer is no longer in business).
I received the parts in the time span indicated upon ordering, and they fit perfectly.
A good experience all around.
Works perfect.
Product arrived, looks great. will be installing on a Workforce man lift. Thank you for quick delivery.
great product and at a great price.
All parts fit and worked as listed in the catalog.
Product was as described. Went in easy and fit perfect.
could not be happier!!!
You guys (Meghan this time) are always incredible. Thank you!
