Abstract: An adaptive braking system for an automotive vehicle is disclosed which permits the proportioning unit valve commonly used in vehicle braking systems to also function as the adaptive braking modulator. The device provides a fluid motor which engages the proportioning piston and urges the latter into sealing engagement with the poppet member to prevent fluid communication to the brakes of the vehicle when an adaptive braking cycle has initiated. Thereafter, the fluid motor continues to urge the proportioning piston in a direction enlargening the outlet chamber of the proportioning valve, to thereby reduce the fluid pressure level communicated to the vehicle brakes. An electrically actuated solenoid valve is responsive to an output signal from an electronic control unit when an adaptive braking cycle is initiated to communicate fluid pressure to the fluid motor for operating the latter.
