Specs:
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.
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.
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.

Today we're going to take a look at the 12-inch Electric Self-adjusting Trailer Brake Assembly Kit, includes the left-hand and right-hand side brake assemblies and they fit 5,200 pound to 7,000 pound axles. Electric brakes are easier to install. They offer more user control than hydraulic brakes. Basically they require only an electric brake controller which we do sell separately on our website. There's no actuate or hydraulic lines necessary. On the brake pads, they do use an automotive grade friction material. It's molded to the brake shoes and the pads are fully bonded so they're not riveted to the shoes.
It gives you a lot longer life, more braking torque. If you notice on the edges of these brakes they are tapered edges and then they do a circular grinding of the pad that gives you less chance of cracking and crumbling that could lead to mechanical lockup. This set happens to be self-adjusting brakes so they do not require the periodic manual adjustment like standard brakes. You can tell they're self-adjusting because if you look at this cable right here it goes around a pulley, attaches to the lever right down here which you'll automatically adjust it as needed. It does use a fine tooth brake adjustment gear so it allows for a more precise setting. There is no break-in period needed following your initial adjustment. If you notice on these backing plates, they are an E-coated backing plate, helps resist wear and corrosion.
They also include the adjuster plugs in the very bottom here. These are the holes that you'd adjust your brakes through, but they do put the rubber plugs in there and it helps keep any dirt and grime from getting into the assemblies and off of the shoes. This does include both the left-hand driver side brake assembly, the right-hand passenger side brake assembly, all the mounting hardware which is a 3/8 inch size mounting hardware which is total of 10 bolts, 10 lock washers and 10 nuts all included. This assembly does meet the QAI and CSA certifications. These are electric brakes so you'll notice the two wires that come out the back here, two black wires. They do need to be connected.
One goes to a good clean ground. The other goes to the brake feed for power. You can use either wire for either function. It doesn't matter which. The application on this again is for most standard hub and drum assemblies including Dexter, Lippard and Alco. The dimensions is 12 inches by 2 inches.
When they say that, what they're measuring the 12 inches would be the diameter so from this pad edge to this pad edge. The ruler on it is 12 inches. The 2 inches would be the width of the brake pad. There's your 2 inches. This is designed for a five-bolt brake mounting flange so your axle does have to have a brake mounting flange which is five bolts to install this on and it is designed for axles that are rated 5,200 pounds, 6,000 pounds and 7,000 pounds. The last thing I do want to mention is this is the left hand, this is the right hand. The way to tell that is when you get them new they'll have a sticker that will tell you that. By chance if the sticker wasn't on there, the easy way to tell is just look at the length of the pad on the shoe. This one goes from here to here. This one goes from here to here. The shorter pad, which is this one right here, is the primary shoe that faces the front of the trailer so that will tell you that this goes on this side which would be the driver's side or left-hand side. If you go to the right-hand side, same way. Just look at the length. Here's the shoe goes from here to here and over here goes from here to here. Again, this is the shorter shoe, the primary shoe, so it would go this direction. That will tell you that this is the right-hand passenger side assembly. That should do it for the review on the 12-inch Electric Self-adjusting Trailer Brake Assembly Kit with left-hand and right-hand side brake assemblies for 5,200 pound up to 7,000 pound axles.

Self-adjusting driver's-side and passenger's-side brakes are 12" x 2". Brake pads are made of durable friction material for improved braking and longevity. E-coated backing plates resist rust. Fit 14.5" to 16.5" wheels.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
They are supposed to be self adjusting, however, they do not seem to self adjust. I have to get under the trailor several times to adjust 720201
excellent 699428
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. They very easily replace the existing. Four bolts and two wires per each and that's it. Replaced bearings and races at the same time. Trailer is a Sailtrailer. 12k capacity. 720606
So happy to have the new self adjusting trailer brakes. The old ones were shot. The price and the speedy free shipping make etrailer the best. Every American company should be run this way. 695998
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
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
Kenny - 09/16/2019Brakes 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
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
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
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 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
Bryan D - 05/07/2019I 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
Ernie T - 08/15/2018These 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
Terry M - 05/18/2018Before and after pictures. I needed to use acetylene torch to remove the old. New brakes fit perfectly and new bolts tightened up well. Will definitely buy again on a few years. Thank you 410556
Perfect fit great price and fast shipping thanks. 644987
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
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
Roger - 07/19/2019I 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
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
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
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
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
Product GOOD Packing and ability of shipping company to deliver without damaging product not so good. It sure defeats the purpose of buying a complete brake assembly if I have to reassemble 3 of the 4. SEE PICTURES 529577
All parts were received and in good condition. Everything fit and went together fine. The final and best test will be the end of Nov. when it goes on a 1500 mile one way trip. Crystal was great to do business with. Very professional. 559351
