A dual-purpose valve for a braking system includes a two-position hydraulic brake control valve coupled to a moveable valve member, a brake control chamber for holding fluid, a brake port for connecting to a brake cylinder, and a tank port for connecting to a fluid tank. Movement of the moveable valve member in a first direction towards a brake deactivation position from a neutral position maintains the hydraulic brake control valve in a closed state causes pressurised fluid flow from the brake control chamber to the brake port and thereby disengaging the braking system. Movement of the moveable valve member in a second direction towards a brake activation position from the neutral position alters the hydraulic brake control valve from a closed state to an open state, and permits pressurised fluid flow from the brake port to the tank port through the dual-purpose valve and thereby engaging the braking system.
