Self-Adjusting Brakes Don'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

These brake assemblies meet the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. These brake assemblies underwent extensive testing to measure stopping distances when braking. These brakes have 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 these brake assemblies 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.

Brake assemblies were delivered fairly quickly, not totally pleased to find they were made in China. They were not packaged appropriately and had a couple of chips on lining. I didn't want to go through the hassle of returning them so I just put them on. I am going to give it a 2 star rating for quick delivery and price point for the product. I would buy again for a trailer that is not used often but would not recommend these for a heavy trailer. 545763

These brake backing plates are great and really cost about the same as buying shoes and springs separately...but this way they come pre-assembled. These come with new mounting bolts and nuts. The nuts DO NOT appear to be of good quality and I would advise against using them. (use your originals) Replacing all four backing plates on my trailer, I broke out the digital torque wrench to torque the 5 backing plate nuts/bolts to the recommended 50ft-lb. At less than 30 ft-lb of torque, I noticed they would not get any tighter, although I was backing up the bolt with a wrench. I removed the nut to find the treads had pulled thru the nut, not cross threaded as I hand tightened them initially, but the threads just gave up. Bolts still looked ok. I replaced with my originals and all is ok. Don't trust these supplied nuts without verifying torque with a torque wrench. If I was etrailer, I would remove them from the kit. 468170

First step was the ordering, Talked to Steve and he was very well versed on what I needed. He gave me his direct line so after I got my bearing #’s and call back it took only minutes to finalize the order. I ordered on Wednesday and received everything on Friday. Wow, Great service. Doubled checked all the items and everything was perfect. Buying the assembly is the way to go. Very quick install. Great experience. 679952

Received brake assemblies three business days after placing the order as promised by Ms. Chrissy J....who provided the finest customer service I've EVER experienced. Ms. J should be commended for her positive, can-do attitude and commitment to this customer! She explained how to measure the brake assemblies so that I ordered the proper size. And then she promptly ordered the parts and explained when I should expect delivery. She also helped me order for grease seals for all four hubs. All the parts arrived when Ms. J told me they would arrive. And, it is such a time saver to replace the electric brake assembly rather than rebuild existing assemblies. This is my second purchase of brake assemblies and it's always easier to remove four bolts and use a butt connector to splice electric to new assembly than spend hours replacing shoes and associated hardware. Chrissy J provides twelve out of ten level service. Yes, she's that prolific! 725435

Decided to spoil my equipment trailer with a new set of brakes. While searching the web I came across Etrailer mostly because their prices were the lowest and the website was easy to navigate. Shipping was free and amazingly fast. Ordered on Tues. and UPS delivered on Friday. Let me start by saying i'm no trailer mechanic! These brake assemblies were just what I needed. I watched the install video and the job went smooth and without any problems. I highly recommend this to anyone intimidated by brake shoes and springs. Just bolt on the entire brake assembly in one piece, replace the hub, a quick brake adjustment and your on your way. It doesn't get any easier! 358278

Brakes were exactly as they said on the website. I would say that I wish they had a cross reference from older brake numbers to the new ones. I received the brakes in 2 days using the free shipping and replaced all 4 wheels on my trailer. 417146

I am replacing the brakes on our 2016 Forest River Shockwave Toyhauler. After removing the wheel drums to repack the bearings, I noticed splattered grease covering the entire brake system of each wheel. Most likely due to me over greasing the EZ lube axles. The brake assembles I ordered and received were exactly the same I was replacing which made the job very simple. I made the initial adjustments then took the trailer out for a test drive to break-in the shoes. They feel better than new. Ordering was very straight forward and shipping arrived a day sooner than expected. I will continue to use etrailer.com for my future trailer/towing needs. Now I know how many pumps of the grease gun it takes to adequately lube each axle. 505053

Weve put on about 4000 miles on the 12 self-adjusting brakes and they feel solid. Travelling through winding canyons and mountain roads have not been a problem. I feel safe when towing my trailer and look forward to many miles ahead.

These are outstanding backing plates and brakes setups. I ordered four of these for my 1997 Sunnybrook fifth wheel. Everything is preassembled! All I had to do was adjust the brakes a little to get the new hubs over them and that was all. Five nuts to remove and replace. Great product! 382238

The Drums, Bearings and Backing plates I installed from your company have worked GREAT! I have not had a single issue with their operation. I even accidentally ordered the incorrect seals, and that was handled perfectly! Thanks so much for carrying and supplying QUALITY parts and having excellent customer service!

These assemblies were a perfect match. Bolted right on and the materials they are made of seem to be comparable to the Dexter assemblies I removed. Only time will tell if they hold up. The pads on the dexter assemblies were coming loose from the shoes and curling at the edges. Hoping these will do better. Gave these a 4 because my main concern when buying online is that things fit and the materials are good. No issues with installation. 565668

I am glad I added these self adjusting brake kits. They seemed to have adjusted correctly, and from what I can tell, the brakes are working well. My 26 foot camper is old and pretty heavy at 5200 lbs dry weight. Seems to be braking evenly and cannot detect any pulling side to side or unevenness when I use the brakes. I am leery about giving 5 stars with only a year of use, but yeah, 5 stars at this point.

I thought I had the right product selected and called customer service but was quickly informed that I would need a different style for my trailer. Glad I called. The shipment came in a timely manner. The parts all fit well and went together smoothly. Only problem was brakes would not engage when energized and after trying to troubleshoot I called for support and was told it had to be a problem with my ground. I was convinced that I had a good connection but upon further inspection the wire popped out of the harness and once it redid it the brakes worked flawlessly. Good product and customer service. 565186

I sent a question to etrailer.com Re: brake assemblies for my 1964 Airstream RV. I got a prompt response explaining how to measure the old brakes on the trailer to correctly size the brakes I needed. Finding the size allowed me to research the hub & bearing assemblies I also needed. I ordered them all with confidence they'd fit. Installed the self adjusting Electric Brake Assemblies along with the Hub kit with bearings, All parts fit together perfectly. Thanks George. 419448

I’m very satisfied with the Brake and Hub Assy’s. I purchased from you guys. I recently had a question regarding Lug Nut Torque on the Hubs. I couldn’t locate any info on the instructions that came in the Boxes nor could I find this Info on the website. I looked in the FAQ’s area & also on the parts info page for the parts I bought. I like finding the Info myself, Usually after hours. I ended up having to call you guys. I talked to Sammie at Customer Service, She didn’t have the exact but did know where to get it. She sent me the Torque Chart with the Torque settings for the Hub and Wheel Type I have. I think that this Info Should be included in the box with the new Hubs and Lug Nuts, Plus easily found on the website. Your Videos and Tips are a Great Extra Plus for us DIY’s like me. I Appreciate Your effforts!! Thanks Again,

I have ordered from etrailer.com on other occasions and for the most part what keeps me coming back in the pricing. They usually have the lowest price for the same original equipment. Be careful if you haven't heard that your product has shipped in a reasonable amount of time, even if their website says they have the item in stock. They will hold your order until they have all the parts to ship. I had not seen a shipped email for almost a week and when I called they said they would have it to ship in mid august, about a month after I ordered. I was told they had a similar item in stock ready to ship now if I wanted to change my order. I appreciated that and did change my order, however, I needed to know that information at the time they knew it because I had to change my vacation plans because I could not get the parts in time to take our 5th wheel. Overall this is a good place to order parts from and I will keep doing so. 414913

Absolutely the best customer service team. I had to call a few times to be sure of the best part size. I ordered four brake assemblies. They arrived quickly and well packaged.

I replaced the (4) brakes on my 8 month old 5th wheel trailer due to leaking grease seals. While I was in there, I wanted to "upgrade" to self-adjusting brakes and this brake kit fit the bill splendidly. Installation was straightforward--simple and easy. Initial brake adjustment was easier with the new kit than adjusting the OEM brakes I was replacing (the adjusting stars line up with the adjuster holes in the backing plates on the new brakes--not so much on the OEM brakes). The self-adjusters work as they should--used to be I'd apply the trailer brakes only from time to time (in a parking lot or fuel station) to check on how the OEM brakes were working and whether or not it was time for a brake adjustment. I still check my trailer brakes in the same manner, however, I've not had to adjust the new shoes since the initial install...very convenient. Overall, I'm very satisfied with my new brakes and the service from etrailer. P.S. I've uploaded a set of "before & after" pictures... easy to tell the difference, eh? Have you checked your brakes lately? 486715

So Disappointed!! This is a review of my order experience, not the product. I needed to replace the brake assemblies on my camper before we could go on vacation. I call to see how long it would take to receive and was told 2 days. I placed the order and received as told. I was about to be impressed until I opened the box. They not only sent the wrong brand, but also the wrong size. I called customer service and had to wait 45 minutes for someone answer. She agreed it was their mistake. I told her I only had two more days to get them on and still go on vacation. I asked for next day delivery. She was able to do that, but said it would ship that day and go 2nd day. The next day, the order had not shipped and the tracking number I was given doesn't even register on UPS. I don't when or if I will receive the correct product. Very disappointed that they would not step up and make it right. 402822

I had a very good experience with my order. Although I don’t have my brake assemblies installed yet they arrived in two days with no damage and seem to be of good quality. I also called to verify that I ordered the correct parts for my 5th wheel rv and they were very helpful and cordial. Will not hesitate to do more business with ETRAILER! 543598

Originally wanted to just repack wheel bearings, so I pulled a wheel to find out which Grease Seals to order. Found brake shoes worn a lot. Because the price on a complete assembly was sooo reasonable, I ordered 4 assemblies plus seals. Turns out the other three (original) brake assemblies had blown grease seals. What a mess! Not to mention my experience of poor to no braking power! So glad I ordered new, complete brake assemblies. No mess, no fuss. Just pull old assembly, cut wires, replace new assembly, splice wires- Done! BTW - one of the new assemblies had a crack in the shoe - probably from being banged in shipping. etrailer replaced it right away and I returned the cracked one. What GREAT service! I have attached a pic of one of the old assemblies w the blown grease seal so you can see how reasonable it is to just buy and replace the whole thing vs. all the clean up that you would need to do if you did just the shoes. 513017

All I can day is WOW! Great customer service fast shipping with awesome prices and easy installation. Having never done anything like this before my wife and I were skeptical about the amount of work that would be required. However I have to say if you can change a tire and grease your bearings you will have no trouble changing brakes. Thank you etrailer! 557829

  • Replacement Electric Brake Assemblies for Mobile Home Axles with 12 inch Brakes
    If your trailer's axles have the 5 bolt brake flange and 12 by 2 inch drums then the brake assemblies, part # AKEBRK-7-SA, will work for you. Verify by measuring the inner diameter and width of the drums. You should know that mobile home axles are designed for one time use and therefore replacement parts can be difficult to find. They generally don't fit the standard parts. If you're running into this you may be better off replacing the axles on your trailer to make it easier later...

You can use the brake spoon adjustment tool # W80630 or a flat blade screwdriver to rotate the star wheel upward (as viewed from the rear of the brake, where the adjustment slot is). Please refer...

  • Can Trailer Brakes be Installed on Stehl Tow Dolly
    There's a couple pieces of information you will need to know to determine if a brake setup like what we offer for trailers would fit your Stehl Tow Dolly. The first thing you will need to know is the bolt pattern of your current wheels. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. This kit has hubs with 5 on 4-1/2 inch bolt patterns. Next thing you will need to know is what spindle you have...

  • Replacement Bearings for a 2007 Weekend Warrior SuperLite FS2500
    I really wish I knew exactly what size bearings your trailer has but trailer manufacturers do not provide us with this information. However, if the Electric Trailer Brake Kit part # AKEBRK-7-SA that you purchased is correct then the most likely hub/drum to pair with these brakes is the Trailer Hub and Drum Assembly part # AKHD-655-6-K which uses a 25580 inner and a 15123 outer bearing. In order to be certain this is the correct hub/drum for you, you can either pull the hubs you have now...

  • Comparing The Electric Trailer Brake Kit # AKEBRK-7-SA To 7K Dexter Brake Assemblies # 23-465/23-464
    The Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA are the equivalent of the Dexter 7K assemblies # 23-465 and # 23-464. They are actually a little nicer than the Dexter assemblies in my opinion because the brake shoe material is cut instead of scored and broken off so there is a cleaner line for less wear and tear at the edge of the material. They are absolutely compatible with the Trailer Hub & Drum Assembly - 7,000...

  • How Do You Know When to Replace Shoes on Drum Trailer Brakes
    On many drum brakes there are wear indicators at the pad material on the shoes. If the pad material is riveted on and you have reached the rivets then it is time to replace them. If you have the brakes adjusted out all the way and the braking is still weak then it is likely time to replace them. If you are having any specific braking issues let me know and I can determine what the likely cause is.

  • Recommendation to Replace Dexter 023-326-00 Electric Brake Assemblies on Trailer
    Based on my research, the 023-326-00 number you found at the back of your existing brake assemblies refers to the Dexter 12 inch x 2 inch electric brake assembly that is designed for 6,000 pound axles and features a 5 bolt mounting flange pattern. If this is correct, you can indeed use the etrailer.com Electric Trailer Brake Kit # AKEBRK-7-SA that you referenced. These 12 inch x 2 inch self-adjusting assemblies do not require periodic manual adjustments like standard units. They are...

  • How to Find Replacement Trailer Hub Assembly for Dual Axle Trailer with 6 on 5-1/2 Bolt Pattern
    To ensure you get the correct replacement hubs for your trailer, you will need to find either the bearing numbers on your existing hub assembly or you can measure the spindle if these cannot be found. The bearing numbers should be stamped onto the bearings themselves. I have attached an image that shows what numbers or dimensions are needed. When measuring the spindle, I recommend using a digital caliper like # PTW80157 to get the most accurate measurement possible. For example, the...

  • Replacement Brake Assemblies for a 7K Trailer with 12 x 3 inch Brake Assemblies
    If you are just wanting to get new brake assemblies you could use part # AKEBRK-7-SA for 12 x 2 assemblies for electric brakes or part # AKUBRK-7 for hydraulic brakes. These measure 12 x 2 inches so they will fit in the hubs you have now, plus they are rated for up to 7,000 lbs axles like that you have. They also fit a brake mounting flange that has a 5 bolt pattern. Although this will work, I recommend going ahead and replacing your drums as well so that you have an entirely new system...

  • Trailer Brakes Not Working Properly After Replacing Brakes and Drum
    There are a few things I recommend checking on your new trailer brake assemblies that may be leading to the poor voltage and performance you are experiencing. First, check to make sure the ground wires are securely attached to bare metal portions of the trailer frame. Ensure that these areas are free of corrosion or debris. A bad or weak ground can cause the insufficient braking power you are seeing. Next, I recommend adjusting the brake assemblies again. You can use a brake adjustment...
