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.

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 waited 6 months after install before writing this. After almost daily towing since installation, I feel like these are every bit as good as the Dexter parts at a fraction of the price.

I love the self adjusting brakes, always stops. I put these on my Columbus 5th wheel after finding out that you need to adjust the brakes every 3000 miles. Found this out after a panic stop and did not stop. These brakes are great, I have 1500 miles on them and just feel safe.

A must on trailers that dont have self adjusters. I feel very safe with these on my trailer.

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.

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.

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,

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.

After a year the brakes are still going strong. They were an exact replacement for the originals. Adjusted very easily. I ordered two set about a year or so apart and they were both exactly the same.

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?

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!


Comments
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!

Solved the brake problems on my 1991 Airstream Excella. The old brakes were worn out from use over 19 years. I initially adjusted the brakes during installation but after they settled in I have adjusted them twice, Now the automatic adjusters will maintain the adjustments going forward. These brakes were an absolutely perfect replacement fit.

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.

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.

I replace the surge brakes on my skidsteer trailer, they always leaked and I hated the jerk it would cause. The electric brake kit was so simple to install, pull the old ones off and slide the new ones on and connect the wires. It was a little hard running the wires due to the trailer being so low and I like the wires to be concealed. The brakes work great, I forget I'm pulling a trailer sometimes because there's no jerking.

New brake assemblies were installed at the same time we replaced all hub and drum assemblies on a trailer used to haul heavy loads. The e-trailer brand of self-adjusting brakes were easy to install and complete the initial adjustment of. There were sufficient written instructions, and as I recall a video, to provide all necessary information for a successful installation. Please understand that we are well equipped to do this kind of work in-house. It might be a minor stretch for someone without the necessary or correct size equipment. Since installation, the brakes have performed as expected and remained in correct adjustment.

Pieces of crap (would use stronger language). Three have worn have worn the the shoes down more than should and one of three will need drum replaced due to metal to metal. Not many miles. Mobile to cincinnati to knoxville to cincy to Knoxville. Had good breaks while they lasted. Will NOT get again.


Comments
Hi Duane, Thank you for your review! Once the brakes are installed on your trailer, you will then want to do an initial adjustment to make sure they are seated right. It is common for self-adjusting brakes to need an initial install. When adjusting the brakes, you will want to make sure the wheel can spin freely, while hearing a slight drag inside the hub. This will let you know the brakes are adjusted correctly. The Brake Adjustment Spoon for Drum Brakes, part W80630 , is the part you will need for the self adjustments. Attached is a video where we talk about the adjustment spoon and how it is used. Thank you!

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.

We installed these a year ago in preparation for a coast to coast trip. We went from California to Florida, up the east coast and back. Have also been out several other times camping locally in California. This brake kit is awesome. I installed them myself and it was very easy. Actually easier than just replacing the shoes, plus it includes the electromagnet assembly, so everything is brand new. Another bonus for me is that my old ones weren't self-adjusting. These are. On anothernote, when my new brake kits came, 2 of the assembly's had popped brake springs. Could have happened in shipping, I don't know. I contacted etrailer just to let them know and they immediately rush shipped 2 brand new assemblies and also paid to have the other 2 returned. I didn't even ask as I could have just put the "sprung" springs back on myself. I give this company a 10+ for customer service and ya cant beat the price for the product!!

I purchased these brake assemblies to replace the old electric brakes on one axle of my 1963 vintage twin axle trailer. Best thing I ever did. The electric brakes were relatively simple to install and have been working extremely well. These new brake assembles have logged more than 8,000 since they were installed and have worked well with the brake controller and break-away cable system I also installed. I am very happy with this product.

Brakes arrived in good order. Though I was concerned about packaging, the brakes were fine. Today I'll be installing, and write another review. 1st time ordering from Etrailer...and first time replacing brakes on my Keystone Toyhauler. Though I "found" what I though were the proper setup, I called Customer Service for help to make sure. Pat, confirmed my choice with her expert knowledge. So far, so good... Now...time to install.
