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.

Perfect fit. A no hassle solution to replacing your brakes. It all comes as one component - minus the mounting hardware. I would have given it 5 stars if it included an absolutely needed part: the four 7/16 x 20 threaded nuts. It does tell you that it’s not included. I figured I could get them locally but couldn’t. Local stores have threads all around the 20, but not the 20. I was wrong so I had to put off installing until I could come back and order them from etrailer. Why not just add them to the brake assembly and raise the price of the assembly by $[XX]? If not for that, I certainly would give it a 5-star rating.


Appear to be quality metal; matched up to my Dexter axles and hubs, no issues.
Arrived a couple days after the break kits and hubs; caused a small delay but no issue for me since did not need the trailer currently.


It pays to order from the experts! I knew something was loose in there so I ordered the works and everything was right. Thank You


Was the exact fit for the 3500 pound Lippert axles on my toy hauler. Easy installation and works great!


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 ordered an electric trailer brake assembly to replace a damaged one on my 14 foot cargo trailer. The fit was perfect and the one I ordered was self-adjusting.


Installed a complete set of 4 of the E trailer self adjusting brakes on my 2002 Doolittle trailer with Dexter 3500 axles....the pre assembled units went on effortlessly, and worked perfect.....would highly recommend them....thanks


They will need bearings regreased. They were not shipped with anywhere near enough grease to make them last around the block. Which means you’ll have to carefully remove the rear seal or buy new ones to grease the inside bearing. And all the hub center caps would not fit and had to roll the edge with pliers a little to get them to tap into the hub.


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 brake parts. I installed them on my travel trailer and the brakes work great!


I'm happy with my new set of electric brakes for my vintage 1928 Wilderness two-axel travel trailer. Fast shipping and helpful customer service... Thanks


No problems after 5,000miles


Very happy with etrailer, great parts and service plus I saved a bunch of money. Highly recommended.
Instead of refurbishing nine year old drums, shoes ,etc. I made an easy change out for the price of a fancy dinner. Thanks et


Got my electric breaks in and put them on my camper,( new parts should come with new hardware) easy online ordering and easy tracking, I will start ordering all my parts here.


So far so good. I ordered a bunch of stuff from several sites th night I got my brake parts. Etrailer was the fastest order forfillment and the first on my porch by far. Everything fit like it was supposed to and this far seems to be working well. Can’t ask for more then that. If they sold a 11/16 ratchet wrench with these things would have gone lots faster.


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.


Install easy, your videos are good



Brakes and new wheel bearings have worked out great!


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


A great price and a perfect fit, thanks


Great product would never shop anywhere else. I never need to worry about this product failing. We went over the Rockies twice with our open car hauler.


Good product for the money. Would recommend ordering from E-trailer.


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.


Fits perfect - thanks for all the help with choosing the correct part. I was surprised there wasn't nuts and washers for the bolts. But am happy with the results.


Glad I found etrailer 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.


Delivered on time great fit doing great 1 year later


Fantastic quality, 0 complaints!
and work perfect. Would absolutely recommend. I’ll be sure to use etrailer for my trailer and hauling needs.

  • 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.

  • 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.

  • Brake Assembly Replacement Recommendation for a 1979 Triple Axle Avion Travel Trailer

For the right hand side you would want the part # AKEBRK-35R-SA and for the left hand side part # AKEBRK-35L-SA. These are self adjusting assemblies too which is nice since you would never have to make any adjustments.

  • 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.

  • Electric Trailer Brakes on a Pontoon Single Axle Trailer with Brake Flanges Turned 90 Degrees
    To determine the correct brakes for your trailer you should find the weight capacity of the axle. It's generally stamped somewhere on the axle itself. Then choose brakes for the same, or similar capacity. For instance, the # AKEBRK-35R-SA and # AKEBRK-35L-SA are right and left hand brake assemblies for a 3,500 pound axle. Your brake flange at a angle, although, isn't typical, isn't an issue. Brakes can still be installed and turned 90 degrees. I would suggest turning them counter-clockwise...

  • Do Self-Adjusting Brakes Need Manual Adjustment After Installation?
    The trailer brake assemblies you have, # AKEBRK-35L-SA and # AKEBRK-35R-SA, are self-adjusting, and after the initial installation will eventually adjust themselves so that they are all working with the same efficiency. The adjustment takes place each time you apply the brakes, and since you only took a short trip, it is likely that they are simply not fully adjusted right now.

  • Parts Needed to Add Electric Brakes to a Dexter 3,500 lb Axle
    For replacement hub drums that will fit your Dexter 3,500 axle you would want the part # AKEBRK-35R-SA. This is an EZ lube hub that also has the 5 on 5 inch bolt pattern you need that will bolt right up to your spindle. For brake assemblies you would then need the part # AKEBRK-35L-SA for the left hand side and then # AKEBRK-35R-SA for the right hand side.

  • Is It Normal for Left and Right Trailer Brake Assemblies to be Different Brands
    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.

Measure the brake assemblies you have. If they are 10 inches in diameter and attach with 4 bolts to your axle then the two assemblies you referenced would fit as replacements.
