Abstract
A hydraulic brake system comprises an electromagnetic normally open inflow valve fluidly disposed between a master cylinder and a wheel cylinder, and a hydraulically shiftable plunger valve fluidly disposed between the electromagnetic inflow valve and master cylinder. The plunger valve is responsive to hydraulic fluid forced out of the master cylinder for establishing a first state wherein flow of hydraulic fluid forced into the wheel cylinder is restricted or a second state wherein hydraulic fluid forced out of the master cylinder into the wheel cylinder is unrestricted.
