At Lippert, we help you take the guesswork out of replacement parts by providing direct replacement components that will get your rig and your equipment up and running like usual. Our replacement standard electric brake assemblies are easier to install than hydraulic brakes and implement an electric actuation system to safely stop your trailer. They are made to fit various hub sizes and axle capacities for many applications. The brakes are easy to adjust and tailor to your trailer. This electric brake assembly is compatible with 13-15” wheels, made for 3,500-lb. axles, and goes on the left side of the trailer (roadside / driver 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.
