Abstract
When the deceleration of a vehicle wheel exceeds a certain chosen value, a wheel-slip-responsive means causes operation of a valve to close communication between a hydraulic master cylinder and a hydraulic brake-applying cylinder and connect this brake applying cylinder to a volume chamber to thereby release the braking force on the wheel until this wheel accelerates back to an angular velocity that corresponds to the linear velocity of the vehicle.
