Abstract
A vehicle brake system with anti-skid control apparatus including a master cylinder, a brake pedal operatively connected with the master cylinder and a wheel brake actuated by the fluid pressure from the master cylinder which includes a cut-off valve disposed between the master cylinder and the wheel brake for controlling communication between the master cylinder and the wheel brake, the fluid capacity of the fluid pressure circuit between the wheel brake and the cut-off valve capable of being increased or decreased, a valve for controlling the cut-off valve and for increasing or decreasing the capacity of the fluid pressure circuit according to the skid condition of the wheel and for selectively changing the speed of changing the capacity of the fluid pressure circuit at two steps in the capacity-decreasing direction, the system being characterized by a signal for controlling the increase or decrease of the fluid pressure circuit at high speed in the capacity-decreasing direction by the cut-off valve for a certain time after the brake pedal is released.
