Abstract: A motor vehicle includes a plurality of wheels and a brake system, which has brakes, which can be hydraulically actuated and are each associated with a wheel. The brakes can be actuated by at least one brake circuit which can be operated by a brake booster. The brake booster can be actuated by a brake pedal to be pressed by the driver. At least one pressure-generating and/or pressure-accumulating device, controlled by a control device to modulate the hydraulic pressure within the brake circuit. A second pressure-generating and/or pressure-accumulating device is provided in the brake circuit to automatically increase the pressure within the brake circuit in dependence on demand independently of the first pressure-generating and/or pressure-accumulating device, when a malfunction is detected in the brake system.
