Abstract
A vehicle braking system having a wheel lock control arrangement with isolation valves for each wheel brake and either three or four solenoid and brake control valves for the system. In one arrangement, each wheel brake and isolation valve has its own solenoid and control valve. In other arrangements two front wheel brakes have separate solenoid controlled operating valves and the two rear wheel brakes have a single solenoid controlling operating valve controlling both isolation valves. Traction control is incorporated into the system so that a wheel brake required braking for traction control purposes may be applied by pump pressure without the vehicle brakes themselves having to be applied through service braking.
