Abstract
In an oil pressure controlled brake system, wherein the brake oil contained within a wheel cylinder is returned to an oil reservoir associated with a master cylinder through an electromagnetic cross valve when the wheel lock or impending lock is detected. The brake system includes a pressure control valve interposed within a feedback loop connecting the electromagnetic cross valve to the oil reservoir. The pressure control valve is so constructed as to suddenly reduce the wheel cylinder pressure to a predetermined value and then gradually reduce the wheel cylinder pressure while the electromagnetic cross valve is energized.
