This basic add-brakes kit is intended for trailers that already have a brake mounting flange and need a complete electric drum brake setup for one 3500 lb axle. It includes brake assemblies, drums, bearings, seals, hardware, dust caps and lug nuts.

Most trailers with a 5 on 4.5 wheel bolt pattern use a 3500 lb axle. The backing plates in this kit use the standard 2.875 inch center-to-center mounting bolt spacing.
