10" x 2-1/4" Hydraulic Brake Assembly - LH

Video Transcript for Dexter 10" x 2-1/4" Left Hand Hydraulic Trailer Brakes Review

Today, we're looking at the Dexter 10" Hydraulic Brake Assembly, part number 23-312. This assembly is for the left-hand side. We can tell this by looking at the shoe lining. The leading shoe will be smaller than the rear or primary shoe. This particular setup is also a single servo with one wheel cylinder and piston that will push out against this shoe lining, creating a wedge effect inside the hub drum assembly. This will give us our braking.

When you couple this left-hand side with the right-hand side, we'll have 3,500 pounds in braking capacity. To tell what our shoe size is, we simply measure across the length of the shoes to see it is a 10" setup. Then we can also measure the width of our shoes lining and see it's 2-1/4". This setup is for a 10" x 2-1/4" hub drum assembly. This setup is also set up to bolt up to a 4 bolt axle flange assembly.

You can see the studs are already pressed into the backing plate and will mount directly up to your axle on a 4 bolt setup. On your initial setup, we'll need to use a star wheel adjuster to just the shoe linings out to create a light drag on the hub drum assembly. This will give us a good even braking. As the shoe linings wear, you'll need to keep making periodic manual adjustments here to star wheel adjuster. This can also be done through the access hole, removing this and the backing plate.

And there you have it for the Dexter 10" Hydraulic Brake Assembly, part number 23-312.
