Abstract
A method of controlling an electric brake having an actuator controllable for moving brake pads against and away from a friction brake surface comprising the steps of (i) retracting a brake actuator after a braking operation; (ii) measuring a parameter indicative of work during the retraction; and (iii) moving the brake actuator to a position at which the brake actuator is ready for a next brake operation, wherein step (iii) is responsive to the measured parameter, wherein the brakes are rehomed adaptively to compensate for brake wear.
