Review of etrailer Trailer Brakes AKEBRK-7-SA


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.
