Manual-Adjust Brakes

With repeated use of these brake assemblies, the brake shoes may move out of alignment, causing less efficient braking performance. To keep the brake shoes aligned and the brake assemblies performing correctly, you should perform routine maintenance.


These brake assemblies should be adjusted after installation and then as needed for the life of the brakes. To adjust the brakes, use a brake adjustment screw tool (sold separately) to turn the adjustment gear on the inside of the assemblies. Continue to turn the gear until the drum surrounding the brake catches on the brake pads enough so that the hub can no longer be turned easily by hand. Then reverse the gear by about 10 clicks. A properly adjusted brake should drag slightly on the brake drum.


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.

Video Transcript for etrailer Electric Trailer Brake Kit Review and Installation

Randy: Hey, guys, Randy here at etrailer.com. Today we're taking a look at the left and the right brake assembly. These electric assemblies allows you to completely replace all of the components in your braking system. So new springs, new keepers, new adjuster, new magnet. Everything's brand new and fresh. This is an excellent alternative to replacing these things piece by piece.

Once you start doing that, you got to take it apart, put it together, take it apart when you have a failure. In this case, we're getting everything on fresh, everything on new. It's going to eliminate a lot of problems and we're also going to get the same braking power out of both sides. Our left side is going to do the same amount of braking as our right side. It's going to make everything a lot safer for us.

Everything's coated with a good corrosion-resistant finish for us as well. This brake dust can be pretty corrosive and having this finish on here is just going to help eliminate a lot of the issues we have with corrosion.We're also going to use an automotive grade pad really nice, wide pad and you can see we've got beveled edges here on the front and on the back. So it's going to reduce a lot of that chattering or a lot of that skipping we get and noise that we often get out of some other type brake assemblies. Now these are what's considered a 10 inch diameter brake assembly and they have the two and a quarter inch wide brake shoes, has the four bolt mounting flange like you've seen. And they're rated for axles up to 35 hundred pounds.

Generally, you're going to see these on trailers that have 13, 14, or 15 inch wheels. Now taking a minute to compare this to other products that we have available, there's really no big difference in them. Even comparing them to more expensive type brands, they're right in line and offer the same quality. Now the only thing you may want to consider is a self-adjusting set of brakes. Those require slightly less maintenance because you don't have to get underneath and tune them in every six or eight months.Now in getting to the assemblies, we need to remove our drum here or if you're going to be doing the drum as well kind of like we are, we need to get this off.

In order to do that, this cap's going to have to come off. We're just going to use a dead blow hammer and if we kind of tap out on it as we rotate, you can see it's going to come off. That one came off pretty quick. It takes, sometimes, a little bit longer than that. But once you get that off, we're going to clean this grease off. That's going to allow us to get to the keeper. Let me see, with that grease off you can see this one has a cotter pin. It's going to be right here. Some of them are going to have different styles. Some of them will have like a keeper that slides over. It doesn't really matter which one you've got, just hang on to it because we will be reusing it.So here are the cotter pin, we need to straighten that guy out, then begin to push it downward and we can get a hold of it on its bottom side. Now we just want to back off this large nut. We're going to hang on to this, we'll be reusing it just like our keeper there. These aren't very tight, generally, so just a pair of pliers those will come off. And then we're going to wiggle our drum just a little bit here, then right here on the end we're going to have this thrush flusher. We're going to get that off. Now if you're getting a new hub, like what we're going to be doing, we're going with a galvanized hub just to eliminate a lot of this rusting issue then you won't need to keep your bearings. You won't need to keep your hub or the seal. If you're not replacing this, if you're just going to be replacing the brake assembly, hang on to these things so you can put them back together.And once that's off, we're going to clean everything up really well. We need to inspect our spindle here. We're going to be looking for any type of damage to it. We're going to be looking for any signs of like major heat, if we see any discoloration on it. Our seal rides right on this lip so we want to make sure that's nice and clean and free of defect. We've got our inner bearing that's going to go here, outer bearing's going to go here. So you just want to make sure everything's nice and smooth. We don't see any cracking, no discoloration. This one looks really good. Now you'll see for a brake assembly, we've gut a stud here, here, here, and down here. Generally, you're going to have four or five. Let's see, it looks like this one is a four. So we're going to back those nuts off that are on the backside here and we want to hang on to those so we can use them with our new brake assembly.You can see here's what our hardware looks like, just the flange nut. Now ours uses an 18 millimeter. A lot of times though, a nine-sixteenths is probably going to be what you need. So just check it out and see what size you've got there. Before you pull your last bolt out, we need to get our wires separated here. These are going to be the two that come in from our plug and then you can see they used quick connectors there, which we don't recommend. They use those to go across to the other axle so we'll have to splice all these together. We'll show you that in just a minute. For our wires here we need to strip them back. The white wire, generally that's going to be a ground, but since it is a magnet we just need to put power through it. So we can connect our wires either way we want.So I'm going to twist the two of those together and to give us great corrosion resistance, we're going to use DW05745. This will be a heat shrink butt connector here on both of them. So we get our wires twisted, get them pushed in there, and then crimp it down really well. Make sure we got a good contact there and do the same thing with these. All right. Now that's going to give us our spot to connect. I'm just going to strip back a little bit more here on these wires. I like to double these over since we're going into a little bit bigger butt connector. Flex it in the middle. Same thing here. All right. Now your assemblies, since you've got left and right, you're going to use the left-hand on the driver side of the trailer. It goes right into that original flange. And for now, I'm just going to throw one nut on it to hold it in place while we make our connections there.So we go in, crimp it down, and then we use a heat source to shrink them. We can use a lighter, we can use a heat gun, we can use a mini torch. We just want to be sure we don't overheat them. You don't want them to melt. The actual butt connector, you just want it to shrink down. You can see as you start to shrink it, it's going to turn kind of clear and the wires are going to look like they get a little bit larger, almost like they're magnified. See that little bit of clear gel that comes out of the end there, just gives you a really nice water-tight connection so you don't have to worry about corrosion issues. Now you want to got through them, we're going to tighten down our nuts here. Now there are three-eighths studs that come out of the back so general torque applications for that are somewhere around 35 foot pounds.Now once we've got everything put back together, you want to check your brakes. You want to rotate it and you want to hear a slight, constant drag like what we've got there. You can just barely hear those brakes dragging a little bit. If need be, if you don't have that, if your tire spins real freely you need to expand those brakes out just a little bit. So you go in the backside with a screwdriver, take that oval-shaped cap out, and that will allow you to adjust the brake tension. If you've got it on there and you can't move it at all, you need to loosen it up a little bit. And this is something you want to do periodically just to check it and inspect it to make sure you're going to have proper braking performance out of your setup.Now to test everything out, of course, we want to make sure our connections are right so we'll hook up our truck or you can hook up a trailer tester, get the wheel spinning, have them apply the brakes and make sure it stops. That's the idea. As you can see, nice and solid there. Go ahead and release. Should release cleanly and we'll be heading down the road again.

by:

Great value. I have not used the product yet.



by:

I did not get a chance to try the brakes because of the condition they arrived in. the brakes where thrown in to a box raw, there was no individual packaging and no padding. The brakes banged around in the box and chipped the brake lining, making them useless. the banging around broke free the springs and pieces where lost through holes in the poorly boxed package. VERY disappointed.



by:

I haven't installed them yet butg the communication was GREAT every step of the way! Thank you. I have purchased from you before and I certainly w9ill again. I will also sing your praises to my friends that have trailers. Thanks you. Bob



by:

Assembly was a cake walk to install bad thing doesn't come with nuts had hard time finding new 7/16×20 next ups sucks got a day later



by:

Brakes look great, but they were packeged by a four year old, resulting in the box being punctured, and the brake parts rattling around, to the extent that two of the four pair arrived missing parts. The springs rattled off, the adjusters rattled out, and parts fell out of the box. To their credit, a return label was issued promptly, and replacements sent right away. But still. Don't they ship items like this every day, hundreds of times a day?



by:

Ship in great shape but might want to put tie straps on to keep the brake shoes form moving other than that the brakes an assembly is great shape



by:

Needs better packaging. Opened the box and the brake shoes had shifted on both units. Will have to remove the springs and realign the shoes. Other than that, it appears okay.



by:

I can’t honestly rate these shoes due to the failure of the shaft seals in the new brake drums I also purchased. As of now my brake shoes will not stop my trailer after cleaning the grease saturated shoes.



by:

One of the left backing plates and one of the right backing plates got messed up in shipping, I think I can repair them but I may be reaching out if I am unable to fix them. the arms that old the magnet fell off and the shoes are not centered on plate



by:

Brakes were great fit right in . Would pay xtra in the future if they came with the grade 8 bolts also almost always old bolts are unusable



by:

I ordered these to replace the original brakes on my trailer after I started having problems with mine (see details below if interested). They are good quality and were easy to mount and assemble. They definitely made a difference in how well my trailer is braking. I definitely recommend these if they are what you need.

However, I will say that the shipping was delayed by about 4 days. This may not be etrailer's fault, but they use UPS and I've been having horrible luck with UPS's shipping service lately. Everything has been delayed. So just be aware that if you order with the standard ground with UPS these will most likely not arrive on time.

The second problem that I had was that I ordered a set of drum/hub combos to go with these on a separate order. After 2 days of seeing no progress on my order I had to email and call to find out that the order was delayed. There was no update from etrailer without me asking. I ended up having to cancel that order and purchase through a local supplier whom I will likely start using from now on.

To detail the braking problems, I purchased my 2008 Toy Hauler about two months ago. We've towed about 1,200 miles with it so far and I noticed from day one that the brakes weren't as responsive as they should be. As we were entering our neighborhood from our last trip my Tekonsha Prodigy 3 started flashing red and reading that there was a shortage and that I had a brake overload and that there were no brakes. This was fairly spiritic but eventually became constant. Based off of information I found from posts on this site, it seemed like it might be one of the magnets not making sufficient contact with the drum. It seems like this was the case. During my repair, I found that one of my grease seals had blown and grease had gotten into one of the brake assemblies and it looked like that entire hub/assembly/etc. had stopped working properly. After replacing the entire brake assembly, drum/hub, bearings and seals on all four wheels everything is working great! I probably only needed to replace the brake assemblies, but decided that for another $350 I would have peace of mind knowing that everything is at it's best!

Thanks etrailer for the helpful information and quality parts!



by:

Product is fine, but they shipped it like crap. Stacked them brake pads together with no padding in between. Only packaging was some paper wrapped poorly around it all. I had to reassemble the units.



by:

i replaced the trailer brakes on my horse trailer Instalation went smooth and easy. They are working perfect and the price was great



by:

Quick delivery. Only problem I have is that the brake shoes were disassembled and apart. Will have to reassemble the springs that came apart.



by:

The assembly's are definitely quality pieces as usual with etrailer, but the packing is hands down the worst I've ever seen. I ordered 4 complete brake units, and when I opened the box every one of them had banged around enough that they were totally disassembled. The box they were in was 2'x3'x8" with one piece of tissue paper. I will definitely continue to use etrailer because of the price and quantity of the parts, but I will definitely talk to someone about packaging before I order.



by:

I expected etrailer to carry better quality products, that is why I stayed away from Amazon. However these brake assemblies are the exact same ones that one could get from Amazon (made in China). I will use these but will buy from Amazon next time.



by:

They came in a timely manner. Installation was simple and the customer service was optimal.



by:

Customer service was great .. with their help we were able to get the information needed to ensure we ordered the correct part..part arrived in good shape ..was packaged well and good quality just as advertised..



by:

Absolutely great service. I have several trailers, and this will be my first stop for all my trailer needs. I would highly recommend this company to anyone. Highly trained staff very courteous and professional and helpful if you need a little guidance. Product was perfect. Replaced complete prepacked hub assembly and complete electric brake assembly. My trailer is same as new again. Thank you for your help. All my parts worked out great.



by:

I received the left side but no right side. Sucks when you're waiting for good weather to do the job and you can't even get started because you're missing parts from your order. Box was intact with those heavy staples.



by:

My order came damaged. I feel you should not have to wait 22 minutes on hold to talk to a customer service person. I have tried calling many times and the wait time is almost the same. I do not have the time to wait. I guess I am going to buy local since the cost wasn’t too different. I guess it is only about the money. There’s no such thing as quality anymore.



by:

The staff at etrailer.com helped me choose the correct brake/axle parts and I received them promptly. After using the trailer brakes extensively for the last year, including a trip to southern Baja, I checked the bearings, seals, and brakes and found them all functioning properly and well within wear limits. I will buy from them again!



by:

Sheila was very helpful and all the parts fit right and worked great. Would definitely order again. Every part I've ever order from e-trailer worked exactly as expected.



by:

Brakes looked great out of box, installed without a hitch, everything fit perfect.

by:

Fit and worked. Glad to have brakes aga in.
