At Lippert, we help you take the guesswork out of replacement parts by providing direct replacement components that will get your rig up and running in no time. Our replacement self-adjusting electric brake assemblies are easier to install than hydraulic brakes, and you never have to manually adjust them after the initial adjustment. These brakes self-adjust during every forward stop, providing up to 50% better braking distance and preventing premature brake line and magnet wear. This is a replacement, forward self-adjusting electric brake assembly for RVs. 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.
