A braking system for a vehicle has a stepper motor which controls the application of friction elements to a rotating part such as a brake drum. A control circuit controls the motor so that an output member is positioned by the motor in accordance with a variable demand signal. In one application, the control circuit receives a brake pressure signal from a transducer and controls the motor so as to compensate automatically for brake wear. In another application, the motor controls a debooster of an antilock brake system. The system also may include means ...
A braking system comprising a rotating part, a friction element for cooperating with said rotating part to provide braking, a motor having an output member for controlling said friction element, and a control circuit for receiving a variable demand signal, said motor comprising a stator and a rotor which is arranged to be brought to rest at any one of a plurality of distinct positions, said control circuit controlling said motor so as to drive said output member to a position in accordance with the variable demand signal and to provide automatic adjustme...
