Review of etrailer Trailer Brakes AKEBRK-10L


Today, we're going to take a look at the quarter-inch self-adjusting brake assembly with the duck heel for 10,000-pound axles. This is a left-hand driver-side assembly. Now, electric brakes are easier to install and offer more user control than hydraulic brakes. They require only an electric brake controller. We do sell those separately on our website. There is no actuate or hydraulic lines necessary with electric brakes. Now, the size on this assembly is a twelve and a quarter by three and three eighths, and it's a left-hand driver-side assembly.

On the size, where they get the measurements for the twelve and a quarter by three and three eighths, twelve and a quarter would be the diameter we've measured shoe-to-shoe, so edge of one shoe to the edge of the other. You can see twelve and one quarter inches. Then the three and three eighths would be if we measured the width of the pad on the shoe itself. Three and three eighths, so it'd be twelve and a quarter by three and three eighths, and this is the left-hand driver-side. The way you can tell that, now on new ones, you always have a tag that'll tell you left-hand or right-hand, and you'll know what side it goes on, but if there is no tag on the brake assembly, the best way is just look at the size of the pad on the shoe. In other words, if you look at this one, here's your length of your pad on this one, and over here it's a lot longer.

So, the shorter one, which is your primary shoe, that will always face the front of the trailer. If the front of your trailer is that way, you make sure the smaller shoe is this way, so then it shows you that this would be the left-hand driver-side assembly. These brake shoes are lined with an automotive-grade friction material. This friction material is fully bonded to the shoe, it's not riveted, so it gives you a lot longer life, more braking torque. The lining, they do tapered edges on the end, and they do a circular grinding of the material to prevent cracking and crumbling that can lead to mechanical lockup. This is a self-adjusting brake. If you notice the cable, it goes around a pulley.

It's attached to a lever. That lever automatically adjusts the gear down here, and the self-adjusting brakes do not require your normal periodic manual adjustment, like on standard brakes. You do your initial adjustment when you install them, and then you should be good from then out. The nice thing on this one is the gear they use is a fine-tooth brake adjustment gear. Gives you more precise settings, and there is no break-in period needed following that initial adjustment.

This does use the cast backing plate, and they do have a metal brake dust shield that comes with it. Also what's nice, is if you look on the bottom of the dust shield, you'll see there's two plugs on adjusting holes. If you ever have to get in and adjust your brakes, there's holes down here to do that. What's nice here is they put the plugs in there. A lot of brake assemblies don't do that, but you do want to have plugs in those holes, because you don't want dirt getting into your brake assembly and causing problems, so the adjuster plugs are included. This is designed- you can see there's seven holes, so it is designed to fit on a seven-bolt brake mounting flange. The mounting bolts, the nuts and the lock washers to install this onto your flange, they are sold separately on our website, and we do list them on this product page as a related product. This whole assembly is certified by USSA standards, and CSA, which is the Canadian standards. Again, the size on this is twelve and a quarter by three and three eighths, it is designed for 10,000-pound axles, and again it is a self-adjusting brake designed to fit the seven-bolt brake mounting flange. This is designed to work with twelve and one quarter inch drums, and these are electric brakes, so you do have to supply power for this magnet to operate. If you notice on the back, they do have a length of wire with two yellow wires, so you do need to connect those. One goes to the brake feed to supply power to the magnet, and then one goes to the ground. Either wire can be used for either function. They're both yellow. It doesn't matter which one attaches to which. That should do it for the review on the twelve and one quarter inch self-adjusting electric brake assembly with the dust shield for a 10,000-pound axle, and this is the left-hand driver-side assembly. .
