Determining Correct Replacement Electric Brakes for Used Travel Trailer
Question:
I purchased a used travel trailer and discovered one of the brakes are bad, drum is grooved badly so I am looking at replacing the entire assembly. Its a tandem axle and the bad one is on the driver side. Trailer GVWR ~7,500lbs - how do I know which brake assembly is correct?

In order to find the correct replacement brakes for your used travel trailer, you will first want to confirm the axle capacities. This should hopefully be listed somewhere on the axle itself or you can look for the primary trailer plate near the tongue that lists this information.
Next, you will want to measure the inside dimension and depth of your existing brake drums, as well as determine the amount of holes in the brake mounting flange on the axle. I have included an image that shows the dimensions you will need to find.
For example, the etrailer.com Electric Trailer Brake Kit # AKEBRK-35-SA includes 10 inch x 2-1/4 inch electric brake assemblies that are designed for 3,500 pound axles. They have a 4 bolt mounting flange pattern.
I have attached a link that will take you to our available selection of electric brake assemblies. You can filter through the different sizes and axle capacities by using the facets on the left side of the page.
