The present inventions provide two methods of controlling brake clearance (410) of a braking system of a vehicle (100) and a method for detecting brake wear, each method including providing a brake actuator (516, 518; 716, 718), a brake input device (520; 720), and a cross-drive transmission (502; 702) having an output (508, 510; 708, 710) and a brake pack (406, 408). These methods include (602,802) receiving a brake input request from the brake input device (520; 720), actuating the brake actuator (516, 518; 716, 718) to apply the brake pack (406, 408), and moving the brake actuator (516, 518; 716, 718) from a first position to a second position during the actuating step. These methods further include (604,606,804,806) detecting an axial movement of the actuator (516, 518; 716, 718) from the first position to the second position, comparing (608,610,808,810) said axial movement to a respective clearance or wear threshold. The first two methods also include adjusting (612,614) a return position of the brake actuator (516, 518) that is offset from the first position when the axial movement exceeds the clearance threshold and controling (612,614) the movement of the brake actuator (516, 518) from the second position to the return position. According to the third method (812) a wear alert message is sent to the vehicle operator if either the first or second axial movement of the brake actuator (716, 718) exceeds its respective wear threshold. Three further inventions for three control systems are provided, each of the control systems performing one of the above methods
