Video Transcript for Dexter Axle Trailer Brakes 23-428 Review

Today I'm going to take a look at the Dexter, 12 1/4 inch, left hand driver side, electric brake assembly, for 7200 pound axle. Now, these are electric brakes, they're a lot 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 actuator or hydraulic lines necessary. Now, these are a manual adjustment brake. In other words, your gear down here is what you would adjust in or out.

Now, manual adjustment brakes do require a periodic manual adjustment. This will include the left hand driver side brake assembly. Now, the mounting bolts and the hardware we do sell separately on our website. Dimension on this assembly is 12 1/4 inch diameter by 2 1/2 inch wide, and those measurements, the diameter would be measured from this shoe all the way over to this shoe. If we put a ruler on it, there's your 12 1/4 inch diameter, and the 2 /12 inches wide would be the width of the brake pad on the shoe. If we put out ruler on it, there's your 2 1/2 inch wide. There's usually brake mounting plans or bolt pattern of 4 bolts.

You can see the 4 bolt holes right there. It does require the use of a 12 1/4 inch brake drum. The wheel size used on these brakes are 15 inches or larger, and again, the axle rating for these that they fit on is a 7200 pound axle. Now, these are electric brakes, so they do have 2 wires right here that need to be connected. One goes to the brake feed, the other goes to the clean ground, and they're both 2 red wires, so either wire can be used for either function. This is a left hand driver side, and the easiest way to tell that now, on a new assembly, of course, there'll be a sticker that you can see. But, if that didn't have the sticker on it, just look at the length of the pad on the brake shoe.

You can see this pad goes from here all the way to here. This one is just from here to here. This is the shorter pad. The shorter pad is always the primary shoe, which means that faces the front of the trailer. That means this is the left hand driver side brake assembly.

That should do it for the review on the Dexter, 12 1/4 inch, left hand driver side, electric brake assembly, for 7200 pound axle.

  • Replacement Electric Trailer Brakes for Dexter 7,000 Pound Trailer Axle
    For trailer brake assembly # 23-428 to fit the drum will need to have an inner diameter of 12-1/4 inches and a width where the pads touch of 2-1/2 inches. I have included a picture showing these locations in a drum. This brake also mounts on a 4 bolt brake mounting flange. The 12-1/4 by 2-1/2 is not a common size though. The most common size brakes for a Dexter 7,000 pound axle is going to be 12 x 2 inch that mounts on a 5 bolt flange such as # 23-180 and # 23-181.

  • Are Self-Adjusting Electric Brakes Available For 7200-Lb Trailer Axle
    The electric brake assemblies we offer for a 7,200-lb axle are manual adjust brakes. We do not offer self-adjusting electric brakes that measure 12-1/4 x 2-1/2 inch. For the right hand you would need part # 23-429, and for the left hand you would need part # 23-428. If you need a brake adjustment tool I recommend part # W80630.

  • Testing and Replacing Brakes on a 2012 Carriage Cameo Trailer
    I've attached an article to help you test the magnets. You also should inspect the wiring for the brake that's giving you issues. If you need to replace the brake you don't have to do both. However, it might be easier in the long run and if the others are showing wear it's a good idea. It can save you time and money later. To determine which brakes to get you can measure the inside diameter of your drums. If they're 12 inch drums then I recommend using # AKEBRK-7-SA. These are...
