Abstract:
A method of automatically adjusting at least one electric actuator of a brake to prevent dragging is provided including measuring a force applied by the at least one electrical actuator to a load measuring device The measured force is determined to be below a predetermined threshold. A predefined offset is subtracted from a current zero torque position of the at least one electrical actuator. Similarly, a drag offset is subtracted from the current zero torque position of the at least one electrical actuator to compensate for a dragging brake condition. The new zero torque position is then stored within a brake actuator controller coupled configured to control the brake.
