Abstract
A hydraulic brake system wherein braking pressures in respective right and left brake cylinders for a right and a left wheel of a motor vehicle are regulated independently of each other by respective anti-skid devices. The brake system includes a first and a second flow restrictor device which are respectively provided in mutually independent passages leading to the brake cylinders, the first and second flow restrictors being electrically controlled by a control device independently of each other so as to restrict flows of a brake fluid through the flow restrictor devices, respectively. The control device activates one of the flow restrictor devices corresponding to one of the brake cylinders, after the anti-skid device for the other brake cylinder is activated to start an anti-skid control of the braking pressure in the other brake cylinder, thereby reducing a rate of increase in the braking pressure in the above-indicated one brake cylinder after the anti-skid control of the braking pressure in the other brake cylinder is started.
