ABSTRACT:
A manually backdrivable ball screw assisted braking system includes a ball drive operated by a reversible electric motor to effect linear translation of the piston resulting in selected pressurization of a wheel brake. The ball drive is assisted in operation by a manually backdrivable ball screw assembly operated by actuation of a hydraulic master cylinder by the manual application of force to the brake pedal.
