Abstract

Brake system of a motor vehicle having front wheels and rear wheels having a hydraulic service brake device. The system further includes an electrically actuatable pressure-providing device, wherein the pressure-providing device is connected to the first and second wheel brakes, comprising a parking brake device having electric-motor-actuatable wheel brakes at the rear wheels, and an electronic open-loop and closed-loop control unit, wherein in a hydraulic fallback operating mode of the brake system, in the case of a brake pedal actuation by a vehicle driver, only the first wheel brakes are connected to the master brake cylinder and supplied with pressure by the driver by the master brake cylinder, while the rear wheels are braked by the electric-motor-actuatable wheel brakes.
