Replacement Electric Brakes Needed on a Kaufman Car Hauler with 10000 lb Axles

Since your trailer was made in 2008, the trailer manufacturer should be able to tell you the exact brand and part numbers for replacement brakes. It appears there were two Kaufman trailer companies, one in Texas and one in North Carolina. The company in Texas closed, so it would be difficult to get specific information from them. I spoke with Kaufman trailers in North Carolina, however, they said they do not have any trailers with a TL designation. There should be an identification plate somewhere on the trailer, near the tongue, that lists the trailer manufacturer information and trailer VIN. If the trailer is from Kaufman trailers in North Carolina, they can tell you the exact brand name and part number of the brake assemblies you will need.

If your trailer is from Kaufman trailers in Texas, the best way to determine which brakes will work for you is to take a few measurements.

There are a few things to look at to determine which brake assemblies will fit your trailer. First, look at the bolt pattern of the brake mounting flange. The brake mounting flange is a plate that is welded at the base of the spindle (see photo) with bolt holes in it. Most brake mounting flanges on 10,000 lb axles have 7 bolt holes, but there are some axles with a 5 bolt pattern. The Dexter Electric Trailer Brake Assembly, # 23-450, that you referenced requires a 7-bolt brake mounting flange.

The next factor to consider is the size of the brake assemblies themselves. If you have your old brakes, measure the overall diameter and the width of the brakes (or width of the brake shoes). You can also measure the diameter of your hubs and the width of the inside of the hub where the brake assembly fits. Most brake assemblies for 10,000 lb axles are 12-1/4 inches x 3-3/8 inches or 12-1/4 inches x 4 inches.

There is going to be a difference in diameter of the axle tube itself. The easiest way to tell is to measure the diameter of it and compare it to the list of axle sizes and weights that I have linked below.
