Lucas Braking System
For the past 25 years, Xceptional Rebuild has been extensively involved with remanufacturing Lucas Brake System Components. We offer every component related to this system from the brake pump, hydromax booster and master cylinder, hydraulic relay and dash control to calipers, individual wheel cylinders and spring brakes. Our most popular version of the rear brakes is the complete backing plate assembly.
