Self-Adjusting Brakes Don't Require Routine Adjustment

Standard electric brake assemblies require manual adjustment of the brake shoes over time to provide longer-lasting and more efficient braking performance. With self-adjusting brakes, the brake shoes are always properly aligned, so there's no need to manually adjust the brakes after the initial adjustment. As a result, you get optimum performance without having to take the time to continually perform this type of maintenance.


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.

These brake assemblies were an exact duplicate of the originals I was replacing. If you zoom on the pictures I took the two right side ratchet assemblies are knocked loose due to the shipping being dropped, no fault of the etrailer. The sturdy shipping box came in very handy for kneeling on while working on the brakes as you can see I’m working in the area with gravel all around the wheels. This is my second purchase from etrailer and both purchases have arrived quickly and worthy of their price.

Who knew lack of forward progress could be so satisfying. After being pushed around by my new trailer, from a highly respected manufacturer, I sought help. First from a repair shop and then a friend with some experience working on trailer brakes. When he pulled the first drum, we were both shocked. It was covered in bearing grease. Turns out the rear seals on all four wheels had been blown out and the drums were coated in grease along with the backing plates and brake shoes. i ordered new self adjusting trailer brakes from etrailer, and the my buddy and I got dirty. Several cans of brake clean and scuffed knuckles later, My new trailer now stops like a new trailer. I can't thank etrailer and my buddy enough. After a year and a few thousand miles, my new trailer brakes just seem to be getting better. Thank for this solid product and, as always, great service.

I replaced the hydraulic surge brakes on my trailer with the electric brakes and hardware. I couldn't be happier. They stop on a dime and they take the burden off of my tow vehicle. Excellent purchase. I'd buy them again in a heartbeat.

Excellent service from etrailer, they had my parts to me in 1 day from the time of placing the order. The electric brake kit seem to be well made and fit nicely onto the Timbren 5200 lb axel assembly with the Dexter trailer hub and drum assembly. I have not ran these on the road as of yet but will give another review at that time.

I really wanted to purchase the Dexter replacement brakes for my Dexter axles, but the original brake material delaminated from the backing making them fail. These replacements are not supposed to do that which is why I purchased them instead. They appear to be working well so far. I've never owned self adjusting trailer brakes before, but if they work as intended that will be a very convenient feature.

I bought this item a year ago. etrailer was the only supplier that had the brakes with the automatic adjuster. As my trailer was originally equipped with this option, I wanted to replace it with an identical set-up. The original brakes were not worn but heavily rusted and did not provide the performance required. The new brakes from e-trailer were reasonably priced, quick delivery, an exact match, and installation was just a few bolts and a couple of wires. My order was quickly processed and the customer service was great. My brakes automatically adjust and now stop my 10,000 lb trailer on a dime. I have owned them for a year with zero issues. Five stars all around. I would recommend this item to anyone looking for a great brake setup for a heavy trailer. Thanks etrailer!

I sent a question to etrailer.com Re: brake assemblies for my 1964 Airstream RV. I got a prompt response explaining how to measure the old brakes on the trailer to correctly size the brakes I needed. Finding the size allowed me to research the hub & bearing assemblies I also needed. I ordered them all with confidence they'd fit. Installed the self adjusting Electric Brake Assemblies along with the Hub kit with bearings, All parts fit together perfectly. Thanks George.

I’m very satisfied with the Brake and Hub Assy’s. I purchased from you guys. I recently had a question regarding Lug Nut Torque on the Hubs. I couldn’t locate any info on the instructions that came in the Boxes nor could I find this Info on the website. I looked in the FAQ’s area & also on the parts info page for the parts I bought. I like finding the Info myself, Usually after hours. I ended up having to call you guys. I talked to Sammie at Customer Service, She didn’t have the exact but did know where to get it. She sent me the Torque Chart with the Torque settings for the Hub and Wheel Type I have. I think that this Info Should be included in the box with the new Hubs and Lug Nuts, Plus easily found on the website. Your Videos and Tips are a Great Extra Plus for us DIY’s like me. I Appreciate Your effforts!! Thanks Again,

On the camper for almost a year so far very reliable and quiet braking system i have put over 5000 miles on them. I highly recommend full replacement instead of installing individual components. I recommend having the brake drums when replaced and properly adjust the shoes when complete. Don't forget to inspect clean and pack or replace your wheel bearings. Wound recommend to order new seals right away and new bolts for backing plated.

These are outstanding backing plates and brakes setups. I ordered four of these for my 1997 Sunnybrook fifth wheel. Everything is preassembled! All I had to do was adjust the brakes a little to get the new hubs over them and that was all. Five nuts to remove and replace. Great product!

The Drums, Bearings and Backing plates I installed from your company have worked GREAT! I have not had a single issue with their operation. I even accidentally ordered the incorrect seals, and that was handled perfectly! Thanks so much for carrying and supplying QUALITY parts and having excellent customer service!

I replaced the (4) brakes on my 8 month old 5th wheel trailer due to leaking grease seals. While I was in there, I wanted to "upgrade" to self-adjusting brakes and this brake kit fit the bill splendidly. Installation was straightforward--simple and easy. Initial brake adjustment was easier with the new kit than adjusting the OEM brakes I was replacing (the adjusting stars line up with the adjuster holes in the backing plates on the new brakes--not so much on the OEM brakes). The self-adjusters work as they should--used to be I'd apply the trailer brakes only from time to time (in a parking lot or fuel station) to check on how the OEM brakes were working and whether or not it was time for a brake adjustment. I still check my trailer brakes in the same manner, however, I've not had to adjust the new shoes since the initial install...very convenient. Overall, I'm very satisfied with my new brakes and the service from etrailer. P.S. I've uploaded a set of "before & after" pictures... easy to tell the difference, eh? Have you checked your brakes lately?

Originally wanted to just repack wheel bearings, so I pulled a wheel to find out which Grease Seals to order. Found brake shoes worn a lot. Because the price on a complete assembly was sooo reasonable, I ordered 4 assemblies plus seals. Turns out the other three (original) brake assemblies had blown grease seals. What a mess! Not to mention my experience of poor to no braking power! So glad I ordered new, complete brake assemblies. No mess, no fuss. Just pull old assembly, cut wires, replace new assembly, splice wires- Done! BTW - one of the new assemblies had a crack in the shoe - probably from being banged in shipping. etrailer replaced it right away and I returned the cracked one. What GREAT service! I have attached a pic of one of the old assemblies w the blown grease seal so you can see how reasonable it is to just buy and replace the whole thing vs. all the clean up that you would need to do if you did just the shoes.

After a few thousand miles of enclosed race trailer towing, I can still turn up the control and lock up the brakes empty. I have not looked at them yet but I have no reason to believe there is not plenty of life left.

Fit perfectly fit not my 1967 airstream camper. However, if you purchase these, new mounting screws are not included, so you will need to purchase 10 new 3/8” diameter bolts and nuts to mount them onto the axle.

I had a faulty electric brake on driver side made a terrible noise when wheel spun, I just replaced the whole assembly instead of piecemeal and then having to open it back again.

All I can day is WOW! Great customer service fast shipping with awesome prices and easy installation. Having never done anything like this before my wife and I were skeptical about the amount of work that would be required. However I have to say if you can change a tire and grease your bearings you will have no trouble changing brakes. Thank you etrailer!

Absolutely the best customer service team. I had to call a few times to be sure of the best part size. I ordered four brake assemblies. They arrived quickly and well packaged. They very easily replace the existing. Four bolts and two wires per each and that's it. Replaced bearings and races at the same time. Trailer is a Sailtrailer. 12k capacity.

Brakes were an exact replacement. Unfortunately, packaging was not up to standards and some of the wiring for the electrical was damaged and had to repair wiring before install could be done.
