R&P Knowledge Hub
Electric trailer brake assemblies use an electromagnet to actuate the brake shoes against the inside of the drum when voltage is applied from a brake controller. The backing plate mounts directly to the axle’s brake flange and serves as the foundation for the shoes, springs, and magnet. Over time, brake shoes and magnets wear due to friction and heat, making full assembly replacement a common service solution. Before ordering, verify axle rating, brake dimensions (12" x 2"), mounting flange bolt pattern, and correct side orientation.
