Keep your trailer's electric drum brakes working reliably with this direct-replacement magnet kit from Lippert. Designed for 12-inch brake assemblies, this kit includes every component needed to restore full braking performance without having to source parts separately.
Electric trailer drum brakes rely on an electromagnet to engage the brake shoes when the brake controller sends a signal from the tow vehicle. Over time, the magnet wears against the drum surface and must be replaced to maintain safe, consistent stopping power. A worn magnet delivers reduced braking force, longer stopping distances, and can cause uneven brake performance across axles.
Lippert's 46-0815 kit gives you everything needed for a clean, complete magnet replacement in a single package. The magnet arrives pre-wired with black lead wires and the retainer clip and spring are included so you're not hunting down hardware separately on a service day.
Includes the magnet, black lead wires, retainer clip, and spring -- everything required for a full magnet swap.
Sized specifically for standard 12-inch electric drum brake assemblies common on RV trailers and fifth wheels.
Manufactured to Lippert's specifications for consistent pull strength and reliable contact with the brake drum surface.
Drops into existing brake assemblies without modification. Pre-wired leads simplify hookup to the brake wiring harness.
Inspect brake magnets at every brake service interval or any time you notice reduced braking response, a brake controller fault, or visible scoring on the magnet face. Common signs of a worn magnet include:
This kit is designed for 12-inch electric drum brake assemblies. Lippert uses 12-inch brakes extensively across their axle lines fitted to travel trailers, fifth wheels, toy haulers, and horse/livestock trailers. Verify your brake drum diameter before ordering -- this kit is not compatible with 10-inch assemblies.
