Abstract
A method of controlling brake clearance of a braking system of a vehicle includes providing a brake actuator, a brake input device, and a cross-drive transmission having an output and a brake pack. The method includes receiving a brake input request from the brake input device, actuating the brake actuator to apply the brake pack, and moving the brake actuator from a first position to a second position during the actuating step. The method also includes detecting an axial movement of the actuator from the first position to the second position, comparing the axial movement to a clearance threshold, and adjusting a return position of the brake actuator that is offset from the first position when the axial movement exceeds the clearance threshold. The method further includes controlling movement of the brake actuator from the second position to the return position.
