ABSTRACT:
In a brake system having a master brake cylinder, in which at least one brake piston, which can be acted upon with brake pressure by a piston rod, forms a brake chamber from which a brake line leads to wheel brake cylinders, at least one valve is incorporated into the brake line for blocking the brake line upon anti-skid control, and at least one pressure chamber, formed by an additional piston, of an additional plunger for feeding brake fluid via a line communicates with the brake line. From the brake line upstream of the valve, a return line for the brake fluid upon anti-skid control leads to the brake chamber of the additional plunger. A valve, in particular a 2/2-way valve, is incorporated into the return line.
