Video Transcript for The Low-Down on the Dexter Electric Brake Assembly w/ Cast Backing

Today, we're going to take a look at the Dexter 12-1/4 inch right-hand self-adjusting electric trailer brake assembly for 15,000-pound axles. Electric brakes are a lot easier to install. They offer more user control than hydraulic brakes. They basically require only an electric brake controller. We do sell that separately on our website. There is no actuator hydraulic lines necessary.

This one is a self adjusting design, which will keep your shoes properly aligned for longer lasting brakes. That requires less maintenance. There's no manual adjustments required. The way you can tell it's a self adjustment, if you look at the cable here, goes around the pulley, attaches to a lever right down here at the bottom that'll control the adjustment gear, so it automatically will adjust the brakes. This one does use the cast backing plate. If I turn this over, you can see the whole cast backing plate right here.

Does use a seven-bolt mounting flange bolt pattern. The mounting hardware to install this to your axle is sold separately. The application again on this is 15,000 pound axles. The dimension on this brake assembly is a 12-1/4 inch diameter by 5 inches wide. What those measurements will be is the diameter would be measured from this edge of the shoe all the way over to that edge.

If we take a ruler and put it on there, that'll get your 12-1/4 inches. The 5 inches would actually be the width of the pad on the shoe. Again, edge to edge, right at 5 inches. This is a right-hand passenger side assembly. The way you can tell that is, besides the label on here, when you get a new assembly, it'll have a label on there, but if that label wasn't on there, the easiest way to tell is look at the length of the pad on the shoe. This one, you can see starts all the way up here, goes all the way down to here.

On this side, it starts right here and goes down to here. This is a shorter pad. Basically, the shorter pad is the primary shoe that'll always face the front of the trailer. If you put it that way, that means this is a right-hand passenger side assembly. This brake assembly is designed to use 12-1/4 inch brake drums. These are electric brakes, so they do require the two wires in the back to be connected. You can see here's your two blue wires. You connect one to a ground, the other to the brake feed for power. Because they're both blue wires, you can use either wire for either function. That should do it for the review on the Dexter 12-1/4 inch right-hand self-adjusting electric trailer brake assembly for 15-pound axles.
