Today, we're going to show you Dexter Self-Adjusting Electric Brake Assembly for Left-Hand Side, part number 23-434. This is a 12-1/4" by 3-3/8" brake assembly. We'll measure the diameter across the shoes and there is 12-1/4". And we'll measure the width of the shoes and there is 3-3/8". When paired up with the right-hand side brake assembly, these brakes are good for use on trailer axles rated at 8,000 or 9,000 pounds. It uses a 4 bolt mounting pattern.

So you want to check your axle to make sure these will fit. There is a pair of wire leads that you use for your electrical connections. It doesn't matter which one you use for ground and which one you use for your power feed just as long as you have a good electrical connection. This is a self-adjusting system, meaning that when you first install the brakes, you will need to manually adjust them and set the proper tension. You'll adjust enough when there is an even amount of light drag all the way around the hub.

Once you have set up the first time, every time you back up the trailer with the brakes applied, this cable will be pulled and if some slightness is to be taken out, the star wheel will automatically be advanced. This is an electric brake assembly. So you want to make sure not to use it on boat or marine trailer applications. The way the assembly works, as the wheel and hub is spinning around and you apply brakes inside the vehicle, this magnet will be activated that will attach to the hub drum inside. As the hub drum drags on the magnet, you'll pull this arm, which in turn opens up the brake shoes and applies pressure.

We know that this is for left-hand side. We have the short shoe that needs to face the further trailer and the long shoe that will need to face towards the back. And that does it for the Dexter Self-Adjusting Electric Brake Assembly for Left-Hand Side, part number 23-434.
