Abstract
A method for detecting a contact point of a brake mechanism. The brake mechanism includes an actuator controlled by a motor. The method includes the steps of establishing a parameter of the motor and a derivative of the parameter and, if the parameter has passed a previous value under no load conditions and the amplitude of the derivative of the parameter has passed a predetermined threshold, responsively establishing a zero position of the motor.
