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.

Product is great and easy to set up however the packaging from which it was sent as was a little less desirable from my seals getting dented and brake assemblies where thrown around in box with tears in box but all should be usable

Oh my goodness, I will have our Customer Service team reach out to you.


I'm probably not the best mechanic that there is but these brake assemblies were very easy to install,it probably took me about an hour per wheel to install,great service from a person named Michelle that helped me to get them shipped quickly,thanks, I would definitely recommend this company for all of your trailer parts....

Mike S.


Doing just great have only pulled our trailer about 6,000 miles and no problems

Oh no. So, I have looked into the notes on your order and it looks like only one was ordered. Awe man, I am so sorry that this happened. Let's get another one ordered and sent out to you right away. I have sent your information over to customer service for them to get this taken care of; you should hear from them within the next 24-48 hours. When you finally receive the rest of what you need, I would love to hear your updated feedback for your project.


2 out of 4 were perfect the other 2 had issue's being I used to work on brakes i took care of it my self including the nicked wire


Easy to install.
When seals fail they
send grease all over the brake asy.

This was easy fix


To team etrailer,
So far,so good. The
complete units were easy to install, although some of the brake assembly units were out of place and had to be reset from shipping and ruff handling. Here are some pictures of the 44 ft pace rig. We have already recommend you to many of our peers. We travel to about 20 events per year and in all kind of traffic conditions, we will let you know how they slow down the unit.
Thanks Al and Matt

Although trailer is not on the road yet the brakes are a exact match and mounted perfectly.


These kits make repairs much easier than replacing just the shoes and provide all new hardware.
Very satisfied with the assistance and response from Etrailer to help me get the parts to fix my RV.


Product arrived quickly, easy to install. I put them on all 4 wheels of our 5 wheel camper. It was cheaper and easier to do it this way than to replace shoes and magnets.


Our Flat bed trailer can do some pretty heavy work however we do not use this trailer all the time.
When the brakes failed we ordered from etrailer and the parts came in and we installed them without much ado.
Thank you for having all the parts we needed. After a year of seldom but heavy usage the self adjusting brakes are still working splendidly.


Shipping took entirely to long


Only had to replace one. Will be checking all again this summer when I re-pack my bearings.


I don't usually do product reviews but wanted to post this one. This was my first purchase from etrailer. I purchased all four brake assemblies for our 5th wheel which I felt was the easiest and best way to go and had my drums machined. It was a very easy transaction, the parts came quickly and fit as they should. Very pleased with the product although I have not put the trailer on the road yet.
BUT- The packaging was very poor. The assemblies were in a carton twice as big as it needed to be without adequate packing and the items rattled around to the point that two shoes were knocked out of place on the backing plates. I was able to correct it and no damage done, this time. Please improve your packaging.
I would definitely buy from etrailer again.

Dennis K.


all good, over 6000 mi and no problems. thanks


I purchased the brake assemblies last spring but did not get around to installing on our 5th wheel trailer this past fall. Packaging was sufficient & all parts were there & in place on the backing plates.The install went well, brakes are working good.I looked up online a brake in procedure for the shoe assemblies & followed it which helped out after the install.Overall I'm pleased with the price of the product,the service from etrailer aswell.

Brake assemblies working great,I like dealing with etrailer.Also good information from reps.


The brakes on my 2002 Komfort 24-TS trailer were completely shot. I needed to replace the drums (cheaper than having them turned). I also needed to replace the electric brake assemblies and to upgrade them from manual to automatic adjusting. I called a couple of times to make sure I was ordering the rights parts and the phone reps were very helpful and courteous. The parts arrived on time and in good shape. I had everything I needed to complete the job. It took me all day to do all 4 wheels but I saved myself a whopping $1,000 over having the shop do the job.

Dave T.




first, Thank you Kate for all of your help. The brake assy worked perfect.


Great customer service! Quick notification of a part that would cause me a delay and they provided some options to work around that delay. Very quick reply and shipping when a part was damaged in transit.


Arrived as advertised. Easy to install with the aid of the online Trailer video.


Bought this backing plate to replace grease soaked brakes on Lippert 2016 7000 lb. axle. Since no one sells just the brake linings, I had to buy the whole assembly. Exact match of the Lippert backing plate. Very easy to replace.



After about 7000 miles still working good


The shipping time was very quick. It was really less expensive and trouble to replace the entire brake assembly than just the shoes.

Hadley R.


No problems! Brakes work perfectly. Always best to replace everything.


They work like advertised and are of good quality, I haven't had them long enough to to know about the self adjusting feature but it looks just like all the rest so I don't know why it wouldn't work. Thanks for getting them to me so quickly.


They fit just like original equipment. Could not imagine doing brakes on a trailer a different way. I don't know how they can sell these brake kits this Cheap !!!!!

Donnie N.


I couldnt be more pleased


I was very impressed with this brake assembly, I purchased (2) two for each side of my 5th wheel right and left sides. I have usually purchaced Dexter brand assembly's, Dexters are a lot more expensive. The more I researched these brake assembly's the more I was impressed, in my opinion these are actually a little better brake pads. When I get ready to buy some more for my gooseneck trailers I will definitely by these again for them. Thanks etrailer.
Sorry, I didn't take any pictures, I was leaving on trip the next day that I received them.


Had two different style tired old units that I rewired only to have brittle old wires break in a different place each time I fixed it. Replaced all four new brakes and now have a trailer that stops, job made easy by getting the correct parts.



did a complete replacement as mag wires were broken brake linings were worn and manual adjusters were not working. easy job replacing and fixed all the problems at one time . will buy trailer parts from ETrailer in the future.


These brake assemblies are cost-effective and work great, and they're easy to install. I replaced all four on my old car trailer and I'm very happy with them. I did an [online] video of my installation.Packing for shipment seemed a little bit marginal, but obviously sufficient as they made the trip undamaged. Note that this purchase was made in June of 2016 (it's now February 2021) so the packing protocol may be different. I'd buy again in a minute.

  • Left Side Self Adjusting Brake Assembly For A 2017 Sportsmen Classic 180tht Single Axle Trailer
    If it feels like the hubs are getting too hot, one item to check is if the spindle nut is too tight and the added stress on the bearings is overheating the bearings and hub that could cause damage to the bearings. I have attached a video of our technician installing a hub on a trailer and how the spindle nut should be tightened to prevent over heating. At the 1 minute and 45 second mark you can see the hub installation. You also will want to try adjusting your brakes since it's possible...

  • Picking Out Replacement Self Adjusting Brake Assemblies for Northwood Fox Mountain 235RLS
    Based on what you listed so far the most likely solution you need for self-adjusting brake assemblies would be the part # AKEBRK-7L-SA for the left hand side and part # AKEBRK-7R-SA for the right hand side but you should check out your current assemblies first to verify this. Make sure your current assemblies are held on with 5 bolts and that the drum has a 12 inch diameter. If you have something different let me know and I'll get you what you'd need.

  • Which Nev-R-Adjust Brake Assemblies for Load Trail 14K Dump Trailer
    To determine which brake assemblies would be needed, you will need to measure your existing brake drums as shown in the provided photo. Since your trailer has a 14,000 lb capacity, you most likely have tandem 7,000 lb axles, which typically use a 12x2 inch brake assembly like # AKEBRK-7L-SA for the left hand and # AKEBRK-7R-SA for the right hand assembly. You would also need to ensure that the brake assembly you choose has a bolt pattern that matches the brake mounting flange on your axle....

  • Replacement Electric Drum Brakes and Drums for Sundowner Horse Trailer
    We can help you select replacement electric drum brakes for your Sundowner horse trailer. You can usually find an axle's capacity on a sticker or plate on the axle itself. You'll naturally want to choose replacement drum brakes that match that capacity, as well as the diameter and width of the brakes currently on the trailer. Once you find the axle capacity you can then measure your brake drums for their size (please see the linked photo). I checked the Sundowner website but their specs...

  • Availability of 6k Brake Assembly that Would Possibly Fit Airstream Trailer Made in 60's
    For 6k rated axles you are most likely going to need the part # AKEBRK-7R-SA for the right hand side and part # AKEBRK-7L-SA for the left. You will need to measure your current assemblies and verify the bolt pattern of how it attaches to the axle as well to be sure. The inside of the drum will been to measure 12 inches by 2 inches deep and the assemblies attach to a 5 lug bolt pattern.

  • Do Hubs/Drums Need to be Replaced When Changing Braking Assemblies
    The Electric Trailer Brake Kit part # AKEBRK-7-SA (part # AKEBRK-7R-SA + part # AKEBRK-7L-SA) will work with pretty much any electric brake controller on the market so there should not be any concern in regards to that aspect. You may however want to do a quick check on the brake controller itself to make sure it is in working order. This can be done by checking for voltage on the blue brake output wire directly behind the brake controller with the manual override engaged. There should...

  • Troubleshooting Weak Trailer Brakes that Are Adjusted Properly and Have Good Magnets
    Is it possible there's grease in the drum which is causing the brakes to not lock up? If you blew out the inner grease seal or it was leaking at all this is a very likely cause. Otherwise it could be a mechanical problem of the assemblies and would need to be replaced. I attached a page that has all of the brake assemblies we offer for you to check out as well.

  • Self Adjusting Electric Brake Assemblies for a 2017 Grand Design Reflection 30 BH 5th Wheel
    I know that has to be frustrating but the prices are determined by an algorithm and not set by someone. This causes price discrepancy's in similar products some times. We have the same brakes sold as a set the etrailer Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K item # AKEBRK-7-SA. These currently have a comparable price as the separate left side item # AKEBRK-7L-SA and right side item # AKEBRK-7R-SA.

  • How To Determine Correct Braking Assemblies for Tow Master Trailer with Unknown Axle Capacity
    It is not required to know the axle capacity when selecting the correct replacement barking assemblies for a trailer axle though it does help. If you want to try and determine this you can look for a sticker on the center of the beam or measure the diameter of the beam assuming it is indeed a round axle tube. The smaller 3,500 lb axles usually have a 2-3/8" diameter whereas the larger 5,200 lb and 7,000 lb axles usually have a 3" diameter. That said, if you know the size of your braking...

  • Do Trailer Brake Assemblies Have to be Replaced in Pairs
    Typically it's best to replace both brake assemblies at the same time since if one is worn out the other probably is but if for some reason one got damaged and the other was still in good shape you could replace them individually. For example for the # AKEBRK-7-SA that you referenced we have the left side with part # AKEBRK-7L-SA and for the right side part # AKEBRK-7R-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...

    When replacing your Axletek 12-GG brakes you will need The Left Hand Assembly # AKEBRK-7L-SA and The Right Hand Assembly # AKEBRK-7R-SA. I like the brakes mentioned above more than the other brakes that we offer because they're a self-adjusting brake that does not require periodic manual adjustment like the standard brakes do. The brakes will fit your 16 inch wheels and will work with axle ratings of 5,200 pounds, 6,000 pounds, and 7,000 pounds. I attached a review video link below of...

  • Can Trailer Brake Assemblies be Mounted Upside Down
    Your trailer brakes will still work with the assemblies mounted upside down where the magnet is above the spindle, but from the customers we know who have done this we have found that the stopping power won't be as strong as if they were mounted the right way. The best solution you have would be to go with self adjusting brakes so that you could mount them the right way and they wouldn't require you to be able to access the back of the assembly. For ones that are the same size as your...

  • How to Determine Trailer Capacity using a VIN, Bearing Numbers, or Axle Diameter
    It is possible that the local DMV or license bureau has the information on the trailer so you will need to call them and see if they do have that information. If they do not there are other ways to determine axle capacity. You can ask the seller for the inner and outer bearing numbers stamped into the metal of the bearings. With those numbers I can determine the likely capacity. Another method is to measure the axle diameter if it is a round axle (if its a square axle I would have to...

  • Do Self Adjusting Trailer Brakes Tighten When Reversed
    Self-adjusting trailer brakes do not tighten when the trailer is reversed. I am not sure what the trailer shop was referring to but self adjusting trailer brakes tighten only when the brakes are applied and the shoes are able to move further than the recommended amount. The mechanism does not have anything to do with reversing at all.

  • Does the Magnet Get Lubricated when Installing an Electric Trailer Brake Assembly
    You do not grease the magnet or where it touches the hub (armature surface). Grease could end up on the pads or where the pads touch the hub and that will cause all sorts of problems. Components that do need lubrication are already lubricated from the factory on brake assemblies that are applicable.

  • Do Self-Adjusting Brake Brake Assemblies Require Initial Adjustement
    I would recommend adjusting the brake assemblies upon installation, but after that they should not need adjustment. The brake assemblies will correct their adjustment each time the trailer is backed. To initially adjust the brakes, jack up trailer and secure on adequate capacity jack stands. Follow trailer manufacturers recommendations for lifting and supporting the unit. Check that the wheel and drum rotate freely. Do not lift or support trailer on any part of the axle or the suspension...
