If you need to replace your electric brake assembly, go with a trusted name. Get a genuine Lippert replacement part! Electric brake assemblies are easier to install than hydraulic brakes, and self-adjusting brakes mean you never have to manually adjust them after the initial adjustment. Forward self-adjusting brakes self-adjust during every forward stop, providing up to 50 percent better braking distance and preventing premature brake line and magnet wear. This electric brake assembly is compatible with 16-17.5” wheels, made for 10,000-lb. axles, and goes on the right side of the trailer (curb side / passenger side). This is a replacement electric brake assembly for RVs and other trailers. Please reference your original equipment label before purchasing. Be sure to inspect and maintain your brakes periodically. Worn-out brakes can lead to axle failure.
