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.

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.


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.


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.


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.
David A - 08/20/2020


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.


I just received the package and haven’t had time to install it yet. However, whomever created the packing process needs a different job. The brake assembly was dropped in a box, with some crumpled craft paper put on top. The box was delivered crushed and partly opened, and one brake shoe had come loose. This isn’t the first time this has happened. Placing a heavy object in a cardboard box is asking for damage (or loss). Please fix this.

Customer Service will contact you.

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.


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.


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!


I bought for these brake assemblies. Installation was straight forward and after a year of use and about 3500 miles, they spray to be performing well. My only concern is one of the four occasionally sticks which heats up that wheel. Backing up a short distance seems to release it, but I'd like to feel more confident that it's working correctly.


I have been very happy with the function, safety and braking quality of my new trailer brakes


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.


The brake shoes had come apart, maybe because of bad packaging! I was able to reassemble them! I installed them on my 24 foot camper and sorta concerned because my stopping power isn’t close to what is was before!!!

Thank you for letting us know about the broken assemblies. Our customer service team should be reaching out to you in the near future.

I had a brake lock-up and was not even able to get the drum off. etrailer helped me get the right brake assembly and matching drum. The replacement was simple, and the added installation video were extremely helpful. eTrailer is my go-to source for parts and information.


Thank you for what you done. It fit and was easy to install. It works great. I have other trailers and I will use you to get brakes assembly for them. Thank You again.


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.


Awesome products and shipping is excell ent….


ordered a wheel and 2 brake assemblies to repair my trailer.
they came in one box, not individually packaged. Banging around in the same box against a steel wheel can't be good for quality. may have internal damage. what were they thinking?

Sorry to hear this. Customer Service will reach out to you.

Awesome having breaks that work like ne w!


Recieved it have not installed it yet. But great price little disappointed that it is from China.


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.

Speedy delivery. Gray prices. Product worked great


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??

  • 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.

If you do not need the nuts and washers then getting the brakes by themselves # AKEBRK-35L-SA and # AKEBRK-35R-SA would safe you a little bit.

    With 10 inch brakes, you can re-use your old drums so long as they are in good condition, and not scored or cracked.

    We can help you with new electric drum brakes for your Coleman pop-up! You will just want to confirm a few details in order to select suitable replacement brake assemblies. First, check the axle's weight rating. This should be on a plate or sticker on the axle itself. Note you need to select a matching set of left- and right-hand brakes.

  • Testing Trailer Brakes that are Getting Weak on a 8-1/2 X 24 Foot Cargo Trailer
    It sounds like the magnets are getting worn and are not supplying the enough force to the brake assembly when the brakes are applied. The first thing I would do is use a voltage tester and check the brake output wire on the trailer while someone uses the manual knob in the cab. If you are not getting full power, you will need to test the brake controller for proper function. If you are getting full power with the manual slide fully engaged, then you will need to remove the hub and check...

  • Do Hub Drums Need to be Replaced to Install Nev-R-Adjust Electric Brake Assembly 23-468
    The Self Adjusting brake assembly # AKEBRK-35L-SA works with a standard 10 inch by 2-1/4 inch hub drum, so as long as your current hub drum fits the standard 10 by 2-1/4 inch size, you would have no problem switching it to the new brake assembly. I do know that Alko makes a 10 by 2-1/4 inch assembly, so your hub drum should be the standard size.

  • Do Nev-R-Adjust Brakes Need any Manual Adjustment
    The # AKEBRK-35L-SA Self Adjusting brake assemblies will adjust themselves as you drive after the initial installation. The front brakes will always bear a bit more of the braking work, because more of the trailer weight is normally on the most forward axle, but it should not be noticeable. We recommend that you do adjust the shoes when you first install the assemblies, so that your brakes are working as well as they can upon the first use. This would be especially helpful in allowing your...

  • Do Nev-R-Adjust Electric Trailer Brakes Need an Initial Adjustment When Installed on a Trailer
    Normally, you would not want to mix different types of brakes on the same trailer because there can be performance issues. With self-adjust brakes like # AKEBRK-35L-SA, you do not have to make any initial adjustments, but it will take longer for them to get set correctly. We usually recommend that you go ahead and make that one initial adjustment so they will be set up correctly for your system. After that, you should not have to adjust them anymore.

  • Do Self Adjusting Trailer Brake Assemblies Have to be Manually Adjusted Initially
    It's possible to adjust self adjusting brakes manually as we've tried to do it here just to see if it was possible. We found that it's somewhat challenging since the adjuster is mostly in the way. We had to use one tool to push the adjuster out of the way and then use the spoon tool to spin the star wheel. That said, the MUCH easier way to accomplish this will be to install the assembly and let the self-adjusting mechanism do the work for you. One way to speed this up is to apply the manual...

It's possible the pads are worn out which is causing the weaker performance but you'll want to inspect them to see if there's any obvious signs of an issue. You can also have a friend grab the manual override of the brake while you listen to each of them to see if you can hear them humming which indicates they are operating. I suspect it's...

  • Why Would Self Adjusting Trailer Brake Assemblies Seem Weak At First
    Self adjusting brakes sometimes take several brake applications till they are fully adjusted. This is a common issue we hear back from our customers when first swapping to self-adjusting brakes. What I'd recommend is take the trailer to a parking lot (or anywhere with low traffic) and drive at a slow speed and grab the manual lever of your brake controller several times and the brakes will eventually tighten themselves properly. It may take several applications but you should feel them...
