Self-Adjusting Brake Doesn'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

This brake assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This brake assembly underwent extensive testing to measure stopping distances when braking. This brake has 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 this brake assembly 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.

Calling this “pre-greased” is potentially dangerous. Nothing wrong with the product itself, but the first bearing I checked had grease slopped on the backside, but not packed into the bearing. It was mostly dry. I ended up buying new seals, removing, cleaning and repacking all the bearings. Just make sure you check or pump grease into the hub before running it.


Glad I found etrailers Fast shipping and Great price for these assemblies! I had to cut the originals off they were so corroded. So I would buy nuts and washers with these. The studs are 7/16x20.



A year later and these assemblies are performing beautifully. The hardware still looks great and the pads are showing normal, but minimal wear. Beautiful stuff from


Very straight forward instaltion. Estimated time per side is about 2 hours with bearing service, removing old nuts was the most time consuming, wich also recommend spraying with penatrating oil the day before.


I am so glad I Purchased the entire brake assembly instead of individual parts. This brake assembly is better than the original since it is self adjusting and I’ll never have to adjust my brakes again. It was a snap to install thanks to video instructions. I highly recommend this product

Good quality parts. Replaced my old travel travel brakes and these are perfect.


Best deal ever. I thought I had to buy the parts individually. Love etrailer


We use these brakes on a heavy loaded Interstate 7,000 lb.trailer, 16 foot, high top, walk in cargo trailer that has dual axles. The route is between southern Missouri, over the Rocky Mountains passes and over the Cascade Mountain Passes into the Pacifice northwest and back to Missouri...over 5,000 miles round trip. Towed by Dodge Dakota pickup truck, I REQUIRE brakes that are reliable, self adjusting, and function together in a consistent manner. These brakes replaced manual adjustment brakes of which enroute wear required multiple manual adjustments along the side of the road to safely cross high mountain passes. The difference between manual and self adjusting brakes and the consistent/straight stoping power of the self adjusting brakes is impossible to overstate. These self adjusting brakes were very easy to install, a mere bolt on job. I literally trust our lives to these brakes....and recommend them with great confidence with tens of thousands of miles of use.


Bought a Hayes 3500 lbs axle that sat in the dirt for years and the pads nearly fused to the hubs. Well worth the money for piece of mind. Only suggestion is to pick up the 7/16-20 bolts with your order (eTrailer, why not just add it to the kit?)

Made my trailer project much easier.

Thank you much!


Upgraded my old worn out brakes with these self adjusting units. They fit perfect and have been trouble free. Previous owner got carried away with the Easy Lub Hubs!!
I personally don't like them, as you don't know where the grease is going. I would rather do the lubing job the old fashion way. Not only do I know it's right, but I get to inspect all the brake components while at it.


These complete replacement brakes are excellent quality, as a retired Heavy Equipment /Truck mechanic, I can rebuild anything,but it was nice to be able to bolt on parts that are of this quality and save several hours labor, while saving money over purchasing parts to rebuild my brakes. These brakes were perfect to finish off a suspension upgrade / overhaul.


One of the first pair tha I ordered over adjusted and dragged the drum got hot , but fortunately not enough to damage anything else. I had to pay for the return. I explained that I was committed to leaving by a specific date. When no tracking came up I called. Returns said that the were behind and it would be several days befor it would be prosessed and a replacement shipped. I call customer service and got a sorry but that’s policy. I then got an automated call asking I was satisfied with customer. Service and did I need to talk to asuppervisor.. I got results, although it still could have faster even after that, I managed to get on the road only a couple days late.the replacement was ok. After several hundred miles the brakes are still ok.


I received my shipment in a box at least 4 times the size it should have been.
This allowed the brake assemblies to move around freely during transit, causing the shoes, brake magnets and adjusters to shift. The parts were poorly wrapped with paper with no bubble wrap or styrofoam to protect the parts.
This picture may show it better. I am planning to order three brake drums
(#AKHD-545-35-K)in the near future. Hopefully, they will be packaged better.


Ordered online and etrailer responded within minutes to let me know the part I ordered was not in stock, but they had another brand of the same part available, which I agreed and with paid 3-5 shipping received package in 2 business days. Installed the same night and all went well. Thanks etrailer for excellent customer service. Will definitely look to you first for additional needs for our trailers.


Great product and secure packaging.


Great stuff and fantastic customer care. Etrailer walked me through the entire purchase and made it very easy for me. I will do business with etrailer in the future??
As you can see I was ready for replacement


fast delivery, easy to install, appear to be of very good quality. overall very satisfied.


I've not installed yet, but I'm horrified that these are not shipped in their own protective boxes. The two assemblies I ordered were just dropped in a box with a little bit of paper, with no way to keep them from slamming into each other during shipment. I'm wondering if they will even work when I install them....we'll see.


trailer brake package has work out quite well.


I installed these brake assemblies on a 53 year old Shasta trailer and they replaced the originals perfectly! Thanks etrailer!


as always great prices and the diy videos are a must see. my go to place for all my car hauler trailer needs


So far so good


Product is fine but packaging was a joke. A very large box was used and only a small amount of kraft paper was used as cushioning. Six to eight of the brake assemblies could have been put in this box. Fortunately there was no damage to my assemblies. I thought that surely this would have been corrected given the number of people that have complained about it. I guess the complaints are not getting to the correct person with the authority to make a change.




Good product at a real good price. Would recommend ordering from E-trailer.


Saves me time and money by ordering thi s!!


Exact replacement for one of my RV brakes that I couldn't get the shoes to back off so that I could get the hub off.

  • Can etrailer Electric Trailer Brakes be Used in Place of Dexter Brakes
    Thank you for the picture. It is a great help in identify the right brakes for you. The etrailer 10 x 2-1/4 self-adjusting brake assemblies # AKEBRK-35-SA is the set for you. They include both a left and a right so ordering 2 sets will give you 2 rights and 2 lefts. The etrailer brakes are high quality. Specifically the pad material for the shoes is actually cut to length rather than snapped off of a long strip. Cutting the material helps prevent cracking and chipping of the pad material...

  • Is the Dexter Nev-R-Adjust Electric Brake Assembly a Compatible Replacement for the Manual Assembly
    The Self Adjusting Electric Brake Assembly, part # AKEBRK-35L-SA is a compatible replacement for the Dexter Electric assembly, part # AKEBRK-35L. They are essentially the same assembly, but the AKEBRK-35L-SA is the self adjusting version. Meaning once you install and adjust the assembly the first time, you will not have to adjust it again. Over time as the shoes wear, the self adjust assembly will tighten itself. The right hand version of the self adjust is part # AKEBRK-35R-SA.

  • Routing Trailer Brake Magnet Wiring to Avoid Abrasion from Moving Parts
    The Electric Trailer Brake Assembly # AKEBRK-7L-SA and similar electric drum brakes like the 10-inch # AKEBRK-35L-SA should have their two magnet wires already routed through the backing plate. This is shown in the linked photo. If you are installing replacement magnets in your brakes you'll want to take care to route those magnet wires so that they do not get pinched by any moving parts. The protective sleeve on the magnet end of the wiring helps protect it from abrasion from the actuating...

    The # AKEBRK-35L-SA would be the left brake assembly and # AKEBRK-35R-SA would be the right side matching self-adjusting brake assemblies compatible with the 10 x 2-1/4 inch brake drums used on a typical 3500 lb axle. The price we charge for them is based on what our vendors charge us and what the others in the market are asking. The mounting studs on the brake backing plate measure 2-7/8 inches apart, center to center.

  • Recommended Brakes For Tandem Utility Trailer With 3,500 Lb Axles
    When selecting new brakes for your trailer with 3,500 lb axles, one important thing to consider is the brake mounting flange. Since most 3,500 lb axles have a 4-bolt mounting flange I recommend the Dexter Nev-R-Adjust Electric Brake Assembly, part # AKEBRK-35R-SA for the right hand and part # AKEBRK-35L-SA for the left hand. You can verify the mounting flange by measuring the distance between the holes on your existing flange. For a 4-bolt you should measure 2-7/8 inches center-to-center.

  • Replacing Non-Self Adjusting Trailer Brake Assemblies with Self Adjusting Brakes
    Yes you can change non-self adjusting brakes to self-adjusting brakes. In order to recommend some brake assemblies, I would need to know the drum diameter. For example if you have the 10 inch drum with the 3500 lb axle, you would need the Right Hand Assembly, part # AKEBRK-35R-SA and the Left Hand Assembly, part # AKEBRK-35L-SA. You will need a left and right hand for each axle.

  • Replacement Electric Trailer Brakes for Tandem Axle Trailer Weighing 5,800 Pounds
    Your trailer likely has two 3,500 pound axles which means that you would need 10 x 2-1/4 inch brakes. To determine if this is the case you can pull off one of the drums and measure the inner diameter and width (where the shoes/pads ride). I included a picture showing where to measure. If you come up with something other than 10 x 2-1/4 let me know. You can use self-adjusting brakes. For the left side use # AKEBRK-35L-SA and for the right side use # AKEBRK-35R-SA.

    That's not an ideal situation but I can understand someone wanting to just replace a single assembly instead of replacing both if they couldn't get a match. So your best option would be to replace the right hand side with the part # AKEBRK-35R-SA so that everything matches.
