Abstract
A vehicular anti-lock braking system includes a source of pressurized brake fluid connected to a pair of diagonally opposed wheel brakes. First and second normally open isolation valves are connected between the source of pressurized brake fluid and the wheel brakes so that fluid reaches one of the wheel brakes after passing through only one of the isolation valves and reaches the other of the wheel brakes after passing through both of the isolation valves. A normally closed dump valve is connected between the source of pressurized fluid and one of the isolation valves so that fluid is selectively routed from both of the wheel brakes and passed through the dump valve to relief fluid pressure at the wheel brakes.
