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" to 15" 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.

I restored an old concrete buggy that I purchased surplus from a rental company. It was in pretty bad shape. I got it sand blasted. I painted it with Rustoleum. I installed new brake parts, master cylinder, and wheel bearing kits. Pretty big project but it came out great! Now I have a great little dual-axle dump trailer designed to carry a cubic yard of ready mix. Works great for short loads of concrete and for drain rock and landscape materials too. I had to use JB Weld to get a good seal on the new plastic master cylinder cylinder-to-brake-hose connection, which was a pain because it leaked and required multiple attempts to fix. Plastic threads on the plastic master cylinder didn't seal with teflon tape. They are easy to over torque/strip! Maybe I did that initially, but JB Weld fixed the problem. etrailer brake assemblies were easy to install and of very good quality. Fast shipping. Thanks!
This review is for the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs - AKFBBRK-35-D. This worked perfectly on my 2008 Bear pontoon trailer with Axis branded 3,500 lb tandem axles and hydraulic surge brakes on one axle. It all went together smoothly without issue and after repacking the bearings and bleeding the system, the brakes now work again. A special thanks to Jameson for your time and recommendation on this kit, it was spot on!
etrailer rocks. Your videos and products are top notch for a DIY kind of guy! Brakes came quick and installed perfectly.
Matthew - 04/25/2021I installed these brakes on a boat trailer. They work fine when dry but after pulling boat out of water and brakes are wet they grab and chatter. I had to install a lockout to keep from grabbing until the brakes dry
Here is some pictures of the before and after pictures of my boat trailer brake restoration. I contacted your customer service and told them what I wanted to do and they sent me all the parts that I needed. Everything went very smooth and all parts fit perfect. Thank you so much for your help and expert advice. Thanks again
Fantastic way to repair brakes on trailer. Actually less cost than buying individual parts to complete the job. Both sides completed in under 2 hours. Will be sure to tell everyone i know that has trailers to used this site for all of their needs. This is the 2nd trailer we have done brakes on, Extremely happy i found this site.
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.
The loaded marine grade backing plates made my job super easy. The fit was perfect and went smooth. I would like to see new nuts supplied with the studded backing plate. My order was processed fast and I received it quickly. Packaging was great.
Very, very prompt shipping! Customer svc rep very knowledgeable about hydraulic trailer brakes. Packaging ensured product arrived without damage. TWO NOTES: The brake line threads were not "well cut" on the right side wheel cylinder. To solved needed to "re-tap" the threads-- additional time required-- To make kit 'complete'--add 8 lock nuts to the package--will add about $0.80 to the kit and solve customers frustration of trying to find lock nuts with 5/8" across the flats. 11/16" across the flats will not work as too close to the welded axle on the mounting flange
Rachael H - 09/14/2017My new brakes look and fit great. This made the replacement on my Heritage boat trailer very easy. The quality looks great and should last me a long time. Thanks etrailer for your help!
Coated for a boat trailer, didn't rust up and fall off like most of them the first year. Adjusters froze and needed cleaning, pads are good still. Coating is starting to wear off, I figure if they are still less than double for the cheapest ones they should last 2x longer so I would use them again, unless I can find something way better. But like most of them , change them out before a long trip each year and that's just the way boat brakes are.
etrailer has great products with fast and reliable service. I buy all my trailer supplies from them. I bought 2 hubs and drums for my boat trailer. I was going to give 4 stars because they did not include the 4 nut and bolts that hold the hub to axle with the product. (the old ones were so rusted they broke off), at the least they could offer for you to purchase them with hub. but I gave 3 stars because I went back to the reviews and others complained about the same thing. problem should have been fixed back then!!
Mike L - 07/24/2019Good product, fit very well and easy to adjust when installed ( lubricated the adjuster anyway) After a year of in and out of the salt water once a week for the season they look very good, a little rust, but not bad. Will see next year how they stand up.
The brakes are great. Easy to install as one whole unit. I can not speak of the quality, I put these on a 22 ft boat trailer and used it for one season. it is not boating season for me right now but i will look at them in the spring when its time to get the boat ready.
They were able exact match for what I needed and they work just fine as a best price I had found yeah. I just ordered a few other things from etrailer and I will guarantee you I will order more again. Great service lady that I talked to told me exactly what to do I followed her instructions and they shipped that to me and just a number of days.
Matched and replaced the OEM brakes on our boat trailer with no issues. The directions which came with them the brakes were not clear on which way to turn the "Brake Adjustment Star" for adjusting the contact of the brakes. The directions did not indicate rotation of the Adjustment Star being different from the left to right side brakes. This created some confusion due to the left side adjusted with no issue but cause the right side to be difficult until correction direction of rotation was determined. These brake work great and we are very pleased with all the other products we have purchased from etrailer.com
My new 10 inch hydraulic brakes are fantastic. They came with a new backer plate and cylinder all ready to go. I also bought new drum hubs and bearings because on my last fishing trip, I barely made it to the driveway before the hub melted to the axle. With an 18 foot Princecraft boat loaded on a 3500 pound axle, that would not be a pretty site 100 miles from home. I was lucky and even luckier to find the etrailer website which had all my trailer needs. Keep on fishing!
The brakes installed perfectly. Only advice is that some axles have a flange or backing plate that will run up against one of the bolts for the brake cylinder. You can take a file to the flange and bring that material down slightly, just enough to clear the mounting bolt for the brake caliper.
My hydraulic brake kit arrived in a very timely way. Great customer service! The four mounting bolts are pressed into the back plate. But the kit doesn't come with the appropriate nuts. Ah, nuts! Back to the hardware store.
Mike L - 07/25/2018Brakes worked out well. Priced right, easy to install/adjust and resolved my trailer brake issue.
Amazon.com - 06/08/2020Easy to install and fits perfectly for my 1985 EZ loader boat trailer. After one year they seem to be working great.
It would be nice if they came with nuts and lock washers. Also, the brake adjustment opening in the backing plate is directly behind the drop axel making adjustment difficult.
I was able to complete the renewal of my boat trailer brake system this week end. All parts fit perfectly, bearing were exactly and grease seals were exactly the right size. Two lower studs on one backing plate needed thread clean up before final assembly, but that was a minor slow down. I am very pleased with my order entry, I believe it was perfect. Delivery was earlier that I expected and free of charge. My thanks to the entire etrailer team, a job well done.
Excellent product for my boat trailer. I really like the backup disengage feature for a boat trailer. No more getting out to lock out at the hitch. Definitely can feel the trailer doing more of the stopping now with these brakes.
