R&P Knowledge Hub

Electric brake assemblies operate when current from the trailer brake controller energizes the internal magnet. The magnet contacts the rotating drum face, activating the actuating arm and expanding the brake shoes outward against the drum surface.

Proper sizing is critical. A 10" x 1-1/2" brake must be used with a matching 10" x 1-1/2" drum. Installing the wrong width assembly will cause improper shoe contact and reduced braking performance.

For best results, replace both sides of the axle at the same time to ensure balanced braking.
