Abstract
A braking system for vehicles includes wheel brakes, a pressure-providing device for actuating the wheel brakes, a master brake cylinder having a primary pressure chamber, a secondary pressure chamber, and a secondary piston. The primary pressure chamber is separated from a first set of the wheel brakes by a first, normally open separating valve, and the secondary pressure chamber is separated from a second set of the wheel brakes by a second, normally open separating valve. A pressure medium reservoir is connected to the secondary pressure chamber in the unactuated state of the secondary piston, the braking system is activated in order to actively build up pressure in the brakes in a by-wire operating mode by the pressure-providing device. In the event of a pressure medium surplus in the wheel brakes, the second separating valve is opened if a release of the brake pedal by the driver is detected.
