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.

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.


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!


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


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.


on time as expected


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


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.


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

David A.


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


Install easy, your videos are good



Brakes and new wheel bearings have worked out great!


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


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


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.


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


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.


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'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


Ordered brakes for my trailer shipping was fast installation was a breeze took about 30 minutes per wheel after watching the video this is the second time I have bought from E Trailer and will continue to buy



Love the parts and price will buy from etrailer again


No problems after 5,000miles


etrailer found the parts I needed and shipped them super fast. The self adjusting brakes were easy to install and work great but didn't come with new wire connectors.

The brake assembly does not come with new butt connectors for installation. If you are replacing the brakes on a single axle trailer, I recommend the heat shrink butt connector kit # DW05745-5 that includes 5 connectors. If you are replacing the brakes on a dual axle trailer, I recommend kit # DW05745-10 that includes 10 butt connectors.


Good price,delivery and fit. Self adjusters will hopefully save me the job of getting my Airstream off the ground to adjust the brakes in the future. So that makes me a "Happy Camper".

Ken S.


After about a year and 10k miles the brakes work just as they should without having to manually adjust them and I am still a Happy Camper!!


Needed new brake hubs for my car trailer. EZ installation and work great on my 7,000 lb trailer.

John J.


I am very happy to report STILL, I am very happy, actually, 110 happy with the brake kit wiring kit I got from yous.I have had zero issues with my car trailer, and have not seen issues with rust, ineffective braking.So I appreciate your products, and will be back for sure!


Part shipped promptly. Installed and always had trouble with brakes adjusting to tight and making hub run really hot. Adjusted 3 times and would always tighten back up and run hot. Asked about warranty. Would have to ship back on my dime as rep said and etrailer would determine if part was bad. My question was how they determine part issue when is not installed as just looking at brake hub it looked ok. Just ordered a new Dexter no adjust brake hub and hoping for better results. Also found a equal part at local auto part store for same money and no shipping fee. Had I had know auto part store stocked brake hub I would and will buy from them. So if you have time shop around.....


I received my brakes quicker than expected and they were an exact fit. Installation was easy. I have a 7000 lbs travel trailer with 2 axles. These brake assemblies are a great value since the magnet alone cost $20. The brakes self adjusted after a few trips around the block. This is the only way to go if you need to replace your brake shoes or magnets. This is a quicker and easier way to go. Don't forget to purchase the nut to mount them with. They don't come with replacement nuts. I won't have to touch the brakes for another 5 years or so!

  • Can Hydraulic Brakes of Demco Tow Dolly be Converted to Electric Brakes
    Since Demco uses 3,500 drum brake assemblies part # DMSB24429M and # DMSB24428M what you'd need is similar 3,500 electric brake assemblies like the etrailer part # AKEBRK-35L-SA for the left hand side and # AKEBRK-35R-SA for the right hand side. To wire these up you'd just need 10 gauge wire like the part # 10-1-1 which we sell by the foot. Then to add a 7-way the easiest way to do that is with the 7-way junction box # e99011.

These braking assemblies are going to be the most economical self-adjusting brakes we have, has a 3.5K axle rating capacity, will work with 13", 14", and 15" wheels, and measure 10" diameter x 2-1/4" wide.

  • Replacement Brakes and Hub and Drum Assemblies that Use L68149 and L44649 Bearings
    The fact that your existing hubs use bearings L68149 and L44649 indicates that the trailer has 84 spindles and the axles are more than likely 3,500 pound axles. The bearing numbers is how we identify things like the correct hubs and capacity so you are good to go. The bolt pattern the wheels use to secure to the hub and drum assembly is the other key factor. I have included a link that explains how to measure for bolt pattern. The hub you asked about, # AKHD-5475-35-K, has a 5 on 4-3/4...

  • Matching Brake Assemblies and Mounting Bolt Pattern of 10 x 2-1/4 Inch Trailer Brake
    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.

  • Trailer Hub and Drums for 3,500 lb Trailer Axle
    We probably have the hubs that would fit your spindle but you need to first make sure the spindle of the wheel that fell of while driving isn't damaged and in need of replacing. If the bearings were so bad the hub and wheel came off most likely the spindle is totally wrecked. The Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K is a 3,500 lb rated hub and drum with a 5 on 4-1/2 inch bolt pattern which comes with bearings.

  • Could Trailer Brakes be Added to 2006 Big Tex 35SA
    If the trailer has brake mounting flanges like yours does you can add brakes relatively easy. It will be a matter of removing your idler hubs, installing assemblies to the flanges, installing hub/drums instead of the idler hubs, and then running the brake output circuit from them up to the front of the trailer. We definitely can help you out but I'll need more info about your trailer to determine what exact parts you'd need. I attached a help article that covers everything you'll need to...

  • 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.

    When it comes time to replace the shoes of trailer drum brakes it is almost always just easier and more cost effective to just replace the assemblies. To determine what assemblies you would need is pretty easy. You need to first determine what size you have.

  • Brake Assemblies that Fit Trailer Hubs # AKHD-655-35-EZ-K
    The correct brake assemblies to go with the trailer hub part # AKHD-655-35-EZ-K you mentioned are the part # AKEBRK-35L-SA for the driver side and part # AKEBRK-35R-SA for the passenger side. These actually don't contact the wheel of the axle at all so the wheel size does not matter with these. The hub you mentioned is what connects to the wheel and is compatible with 16 inch trailer wheels.

  • Brake Drum and Assembly Recommendation to Replace Drums Markes 8-247
    The Trailer Hub part # AKHD-545-35-G-K would be the perfect choice for a hub and drum assembly since it is a different brand, but cross references to the same hub and drum that you currently have. It is galvanized for corrosion resistance. For right hand electric brake assemblies you would want the part # AKEBRK-35R-SA, and then for the left hand side you would want the part # AKEBRK-35L-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.

They told me that you have the brake mounting flange mounted on your axle so what you will want to do is add a new hub and drum, the brakes, and wiring for your trailer, and you should be good to go.

    You have the standard brake mounting flanges on your axle. If you want to get really technical, the bolt holes should actually measure about 1/16 larger than 2-3/4. That is the standard dimension for 3,500 lb axles. If you are looking for hydraulic brake assemblies, I strongly recommend the 10 Inch Free-Backing Dacromet Brake Assemblies, # AKFBBRK-35L-D for the left hand and # AKFBBRK-35R-D for the right hand. Free-backing brakes will not lock up when you are backing up the trailer and...

  • Can Hydraulic Disc or Electric Drum Brakes Be Added to Demco Tow Dolly
    It may indeed be possible to add brakes, like the Titan hydraulic disc brake kit # T4843300 you referenced, to your tow dolly but a few things need to be checked. Generally it is preferable to use electric drum brakes on a tow dolly since their power can be adjusted by the brake controller that would be installed in the tow vehicle. A disc actuator requires the forward-momentum of the dollied vehicle to engage the brakes, and this would make it essential to match the actuator to the weight...

  • Parts Needed to Add Electric Brakes to a Dexter 3,500 lb Axle

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. I attached a picture that shows how to wire up both axles for you to check out as well.
