Review of Dexter 12" Right Hand 7K Electric Trailer Brakes

Today were going to take a look at the 12 Electric Brake Assembly for right hand side, part number 23-181. This is a 12 by 2 brake assembly. Well measure the diameter across the shoes, and theres our 12 mark. Then we will measure the width of the shoe itself, and theres our 2 figure. This brake assembly when paired with the left hand side is good for axels rated up to 7,000 pounds. It mounts using a 5 bolt mounting pattern, so you will want to check your axel and make sure its got the 5 bolt mount.

There are a pair of wire leads that you will use for your electrical connections. It doesnt matter which of the two you use for ground and which you use for power so long as you have a good solid electrical connection. These are manual adjusting brakes. So when you first install them, and over time as the shoes wear you will manually need to adjust them. To do this you will push on these teeth on the star wheel and it will open up the pin which will in turn open up the shoes.

This is an electric brake assembly so youre not going to want to use it on marine or boat trailer applications. The way your brake assembly works is the drum rotates around the assembly and when you apply brakes inside the vehicle this magnet will become charged and will stick to the inside of the hub. As the hub drum rotates around it will drag on this magnet, pulling this arm, which in turn opens up the brake assembly and applies brake pressure. You can tell that this is for the right hand side by virtue of the length of the shoes. The shorter shoe will be for the front of the trailer, and the longer shoe will face the rear.

And that does it for the 12 Electric Brake Assembly for the right side, part number 23-181. .
