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.

Video Transcript for etrailer Self-Adjusting Electric Trailer Brake Review

Speaker 1: Today we're going to be taking a look at the self-adjusting electric trailer brake with dust shield for the right hand side, for a 10,000 pound axles. Part number AKEBRK-10R. They're also available for the left hand side using part number AKEBRK-10L. So here's what our brakes are going to look like. The really nice things about this set is the fact that it's going to be a complete unit. We're not going to have to worry about replacing springs or individual pieces.

It's just going to be a simple, full ton design. Our brakes are a self-adjusting design, which means that once we have them set initially, we're not going to have to crawl underneath our trailer and mess with adjusting the brakes because they're going to do it for us, which is always a nice thing cause it's one less thing that we have to worry about.The way we're going to make our initial adjustment is going to be at the plug back here. It's going to keep all that dirt and debris out from the inside of our brakes. We're going to have a fine tooth gear to get our brakes set how we like them and set the initial tension. Our pads are going to be bonded, not riveted.

So we're not going to have to worry about those rivets gouging into our drums. They're going to have a nice tapered edge that's machine cut rather than snapped off. We don't have to worry about any kind of chipping or breaking on the edges here which is going to give us more braking torque and give us a long lasting brake pad.Our brake assemblies are going to be a 12 and 1/4 inch diameter and they're going to be a three and 3/8 inches wide. They do have a seven bold mounting flange so make sure to check the trailer and make sure that it will match up. They are designed to work with 10,000 pound axles.

Just keep in mind that the mounting hardware is sold separately but you can pick it up on our website at etrailer.com. Now that we've seen what our brakes look like and going over some of the features, let's show you how to get them installed. In order to get our new parts on we're going to have to take our old parts off. We're going to start by taking off our oil cap. Now, we have already drained our oil.

If you haven't, it'd be a good time to go ahead and pull the cap and get as much oil out as you can so you don't make a big mess.In order to get the nut off we're going to have to bend these tabs out of the way so that we can spin it off. We're going to take a flat head screw driver and a hammer and tap them out of the way. You can take a large pair of channel locks and loosen that nut up. Start pulling everything out. Remove the outer nut and then the retaining washer. Then the inner nut. We can pull the flat washer that was behind it off. Then finally, you can start working our drum back. Once we have enough room, we can pull the bearing out. Now would be a good time to go ahead and inspect the bearing for any kind of wear or any scoring, or major heat marks. Before we get too far into it. We'll go ahead and clean it off and make sure that our bearing is in good shape.Now that the outer bearing and all the nuts are removed, we go ahead and grab our drum. We're going to start working it off the spindle. Sort of be careful because it is rather heavy. Make sure you have a firm grip on it, then we can remove it and set it aside for now. With the drum off, now would be a good time to go ahead and inspect the spindle and all the other components on the inside, cleaning it off. Making sure there's no major wear on the spindle or anywhere else. On the back side of our brake we're going to have our electrical wires. We're going to go ahead and cut them so we can remove the break and not have to worry about it hanging up. You just want to make sure you give yourself enough slack so we can reattach the new ones.On the outer side of our brake assembly we're going to have several bolts that are holding it in place. We're going to have three on each side. And then there's actually going to be one directly behind the magnet here at the bottom. Now there is a bolt so there is a nut on the back side. To help out, I'm going to take a 5/8 socket and I'm going to break them loose and let them free spin so it's not so tough getting them off. If you can't break the bolts loose on the front side you can take a large ratchet or breaker bar and break the nuts loose on the back side making it a little bit easier for those nuts to come off.Then I'm going to take an 11/16ths wrench and hold the nut on the back side while I use a 5/8 socket to remove the bolt. I will repeat that for all of the remaining hardware. The last bolt at the bottom of our brake assembly is going to be rather hard to get to. Since we're replacing our brake assembly, we can take a flathead screwdriver, coming in to where the magnet is, I'm going to pop that clip out that's holding the magnet in place that way we can pull the magnet off and have a little bit more room to work with. It may be a little difficult to get to, but with the magnet out of the way it will be a little bit easier.Now, with all the hardware removed, we can remove our brake assembly. It may be stuck on there pretty good. Just grab a hammer and give it a few taps on the back side and break it free. Then we can remove it. We're going to go ahead and clean off the axle here. You don't need to make it spotless. You just want to get the big debris off so it's not going to interfere with us putting our new assembly on. We can take our brake assembly and go ahead and slide it over the spindle and the axle. I want to mention that there is a sticker that's going to tell you that it's right hand. Also, right at the top of our brake assembly, it's going to be stamped into this piece of metal right here.However, if both of those are worn, the sticker is missing, or you just can't find it, the easiest way is going to be looking at the brake shoes themselves. With the magnet on the bottom, you'll notice that the shoes are going to be two different sizes. The smaller one is always going to be going towards the front of the trailer. We know that this is going to be the right hand side because we're working on the right side and the smaller shoe is facing towards the front.Since our hardware holding our brake assembly on is pretty worn and rusted .You can see that it's covered in rust and half the threads are rolled over. It's really not going to be safe to reuse those so we're going to be replacing it with a new hardware kit. You can just line up the holes on a backing plate and on the axle. We're going to put our bolts in place and then we can get the rest of the hardware in. One thing to keep in mind is you want to watch your wires. Make sure they're out of the way and they don't get pinched in between the backing plate and the brake assembly.Now, just like what came off, we're going to be putting on a lock washer and then a hex nut to hold the bolts in place. We're just going to get all these on there hand tight so we don't have to worry about the assembly shifting or falling down. We can get ready to connect the wires coming off of our brake assembly to the wires that are ran up front. We're going to go ahead and strip back the ends of our wires. They give you plenty of wire here on the brake assembly. We're going to make sure that we have enough, it's not going to get tangled up, but that we also have enough slack so the suspension can still move.We're going to have two yellow wires coming off the end. It doesn't matter which one we connect to but we're going to to take a butt connector. These aren't included in the kit but you can pick some up on our website. We're going to crimp our butt connector in place onto each one of our wires. We're going to take each one of our yellow wires . I'm actually going to strip back a little bit more since they're thinner wires. Now, since I stripped off more than normal what I'm going to to do is, I'm going to twist my wiring together. I'm actually going to fold it in half. It is a rather small gauged wire. That butt connector will grab onto it a little bit better. I'll do that for each one of my wires. Then we can make our connections to our butt connector.These are heat shrink butt connectors. I'm going to take a heat gun and shrink them down. I just want to mention if you are using open flame like a torch or a lighter, you want to be extra careful not to burn or char the wires or the connectors themselves. Now, since this connection is on the outside, I'm going to take some electrical tape and wrap up my connectors to help protect them a little bit better. Now I'm going to take a couple zip ties and tie the excess cable around the axle. Again, just making sure that I leave myself enough room for the suspension to flex. You want to make sure that the wires aren't going to rub or chafe against anything. They're going to be nice and out of the way.With our wire connections made we can come back and tighten up our seven bolts holding our assembly onto the axle. Again, I'm going to be using a 5/8 socket to hold the head of the bolts and an 11/16ths wrench to hold the nut on the back side. I'm just going to go around and snug them all up before I tighten them all the way. Now for the one that's behind the magnet, you're going to want to take a 5/8ths wrench and kind of sneak it in underneath the spindle here to where you get ahold of it. On the back side you're going to want to take either a ratchet wrench or a socket and snug up the nut on the back side.Before we put our drum back in place we want to make sure that our spindle is nice and clean. We don't want any dirt or debris or anything else getting in the way, preventing our drum or our seal from seeding properly. We can clean any kind of debris that got in the hub. Clean that out. Then we can start putting our bearings and all the washers back in place. We're going to remove our cap to fill our oil. We can fill our hub back up. Once it's full we can replace the cap and then we can adjust our brakes.On the back here we are going to have a couple plugs. Take a flathead screw driver and we can pop them out so that we can access the gear to make our initial adjustment for our brakes. We can either get a brake adjustment tool or a flathead screwdriver and we're going to want to turn that gear until the brakes are adjusted the way that we want. Make a couple turns. We can spin our hub to see how much drag and how much movement we have. Once your brakes are adjusted you can go ahead and put our plug back in place. That will finish up your look at the self adjusting electric trailer brake with dust shields, measuring 12 and 1/4 inches for 10,000 pound axles.

A complete assembly makes installation easy 675442


Works just like they should and appear to be very good quality. The price is excellent and the best price around for a quality part. I purchased two left hand and two right hand brake assemblies to replace old busted brakes on my dual tandem dump trailer. I called to order and spoke with Christina J who was extremely professional and got my order out the same day I ordered even though I was close to the cut off time for shipping. The items arrived the very next day but unfortunately the brake shoes had been damaged in shipping and were not usable due to less than ideal packaging. I called etrailer and spoke with Benjamin A, he was very helpful and had me send a couple pictures of the damage while we were on the phone and within minutes had another replacement set sent out to me that same day and arrived the very next day. I am extremely happy with my customer service experience and this level of service is hard to find these days. The brakes are working good and I’m happy to have given my hard earned money to etrailer. This was my first purchase from them and I wish I would’ve worked with them sooner. I will be a repeat customer! 649376

  • Replacement 12-1/4 x 4 Inch Brakes for 10,000 Pound Dexter Trailer Axles
  • If your drums are 4 inches wide where the brake shoe pad makes contact with the inside of the drum then you will need 12-1/4 by 4 inch brakes # 23-438 for the left and # 23-439 for the right. If you are measuring the overall depth of the drum then you likely need the 12-1/4 by 3-3/8 assemblies such as # AKEBRK-10L which would fit on Dexter axles.

  • Dimensions for the 7-Bolt Mounting Pattern on the Electric Trailer Brake # AKEBRK-10R
  • Although we do not have a schematic for the 7 bolt mounting pattern, I do have the measurements for the patterns. The 7 bolt mounting patterns for both the Electric Trailer Brake with Dust Shield, Right # AKEBRK-10R and Left # AKEBRK-10L, varies between 2", 2-3/16", and 4" depending on what mounting hole locations you are looking at. I have provided a picture that shows the dimensions for you to reference.

  • Does Brake Assembly part # AKEBRK-10R Fit Dexter D100 Axles
  • If your Dexter axles are 10k axles that require 12-1/4 inch by 3-3/8 inch assemblies the part # AKEBRK-10R would fit. Everything I am finding on the Dexter D100 axles is that they are 10k so these would be a fit. For the matching left side you'd want the part # AKEBRK-10L.

  • Recommended Replacement Brake Shoe Kits for Dexter 12-1/4 x 3-3/8 Inch Electric Brakes
  • The 12-1/4" x 3-3/8" Electric Brake Shoe/Lining RH # BP04-255 and Left Hand # BP04-245 are a fit for the Dexter cast backing plate. The Dexter brand is 12-1/4" x 3-3/8" Electric Brake Shoe Lining--Right Hand # BP04-250 and Left Hand # BP04-240. If you want the entire assemblies, we have # AKEBRK-10R and # AKEBRK-10L which are self-adjusting to maintain the best braking. This is my recommendation because you get an all new assembly ready to install and use. I've attached videos to assist.

  • Comparing Dexter and etrailer Brand Electric Trailer Brakes for 10K Axles
  • We recently had a short training session in which the difference between our brakes such as # AKEBRK-10R and Dexter brakes were revealed. The biggest difference is the brake pad material. It is thicker on our house brand brakes. Also, on our brakes the pads are machine cut whereas on the Dexter brakes the sections are snapped off. The benefit to having them machine cut is a smoother edge. Snapping off the pad sections leads to chipped edges and fine cracks in the material. The performance...

  • Individual Assemblies that Come with Electric Trailer Brake Kit # AKEBRK-10
  • Yes, the left and right hand assemblies of the kit part number # AKEBRK-10 are available as part numbers # AKEBRK-10R for the right hand side and part # AKEBRK-10L for the left hand side. The kit does not include anything beyond just the two assemblies so if you happen to catch our pricing algorithm offering them individually at a better price that's what I would recommend you go with!

  • Replacement Electric Brakes for a 1991 Fleetwood Wilderness 5th Wheel Trailer
  • I am fairly certain your 1991 Fleetwood Wilderness uses 10 x 2-1/4 inch brakes. But to be sure you can measure the inner diameter and depth of a drum. For a pair of brake in this size I recommend etrailer brakes # AKEBRK-35-SA which includes a left and right assembly. These are self-adjusting brakes that only require an initial adjustment at the time of installation. After that they will adjust themselves. I have linked a video featuring these brakes for you.

  • Will The Brake Assemblies For A 7 Bolt Flange Work With The 4 Bolt Flange?
  • For a 9,000 lb axle with 4 bolts, you will want the Dexter Electric Brake Assembly, RH 12-1/4" x 3-3/8", # 23-435 and the matching left side assembly # 23-434. These are the only assemblies for the 4 bolt mounting plate and the 7 bolt plates are not compatible. Unfortunately, the Electric Trailer Brake with Dust Shield - Self-Adjusting - 12-1/4" - Left Hand - 10,000 lbs, # AKEBRK-10L, is an example of the 7 bolt flange that is not compatible with your axle.
