Abstract
A binary valve (40) for use in an anti-lock brake system having an electronic control unit (12) responsive to a wheel speed sensor (14) for optimizing the utilization of pressurized fluid to front (20,22) and rear (24,26) wheels during a brake application. The binary valve (40) is responsive to an input signal from the electronic control unit (12) derived by calculating when a complete stop (54) of a vehicle would occur and at approximately five seconds prior to such complete stop (54) decaying the fluid pressure supplied to the front (20,22) brakes to provide a transition (58) between the rate of deceleration (52) and a delayed complete stop location (56).
