Today we're going to show you the 12" Electric Brake Assembly for Left-Hand Side, part number 23-105. This is a 12" x 2" brake assembly. We measured the diameter across the shoes and there's our 12". Then we measure the width of the shoe and there's our 2" figure. When paired up with the right-hand side assembly, these brakes are good for trailer axles rated up to 6,000 pounds. The assembly mounts on a 5 bolt mounting pattern.
So you want to check your trailer axle and make sure that it's got the same 5 bolt pattern. There are a pair of wire leads that you will use for your electrical connections. It doesn't matter what you use for ground and which you use for brake feed so long as you have a good solid electrical connection. These are manually adjusted brakes. So when you first install them and set them up and over time as the shoes wear, you will need to adjust the brakes.
To do this, push on the star wheel and it will rotate and expand this pin, opening up the shoes and making the brakes fit tight. So this is an electric brake assembly. You're not going to want to use it on boat trailer or other marine trailer applications. The way the brake assembly works is the drum rotates with the wheel around the brake assembly and you apply the brakes pressure inside the vehicle. This magnet will become charged and it will adhere to the drum.
As the drum moves, it's going to drag along the magnet, pulling this arm which in turn will open up the brake assembly and apply pressure. You can identify this is the left-hand side by looking at the length of the shoes. The shorter shoe is to be facing the front of the trailer, whereas the longer shoe is going to be facing the back. And that does it for the 12'' Electric Brake Assembly for Left-Hand Side, part number 23-105.

This was not the first time I have purchased from "etrailer.com". The first time being several years ago. I purchase may products on line and honestly this company/source for the products they offer and the prices, processing, shipping and support they provide is very honestly as good as I have ever encountered. Their staff are completely helpful and "KNOW" the products they sell. I have my own RV and have hauled/delivered RV's Commercally for years, through out the lower 48, Canada and Alaska. No, I don't write reviews very often and only after I have honest experiences with the sources that enable me to evaluate them, good or bad. 31057

EXCELLENT...... START TO FINISH. Fantastic service, great prices, quality products. Here's a before and after picture. It only took 30 minutes and basic tools to make the replacement. So much better than trying to clean up the old rusty one. Thanks again, Bill Borland in Michigan 23873
