Abstract
A hydraulic dual-circuit brake system for automobiles, comprising wheel brakes positioned at the front and rear wheels, a master brake cylinder, brake lines for transmitting brake pressure from the master brake cylinder to the wheel brakes to actuate the latter, a brake pressure regulator device incorporating a hydraulically operated switching off device interposed between the rear wheel brakes and the master brake cylinder, and a brake slip regulation device including a hydraulic unit, sensors for providing a signal output representative of wheel movement behavior, and an electronic anti-skid control and regulating device responsive to the signal output for controlling the hydraulic unit to affect the brake pressure transmitted by the hydraulic unit to the switching off endangered wheel brake. The hydraulically operated locking device of the brake pressure regulator device responds to the brake pressure transmitted by the hydraulic unit to the locking-endangered wheel brakes and modifies the operation of the brake pressure regulator device to affect the brake pressure delivered to the rear wheel brakes by the brake pressure regulator device.
