Abstract
A brake system is provided in which, in the normal operation, the brake pressure in the wheel brake cylinders is generated in a power-assisted manner and the master brake lines are closed by change-over valves. During a functional disturbance, the brake pressure in the wheel brake cylinders is built up by way of a master brake cylinder, such that, when the brake pressure control device operates normally also when the switching valves are closed the brake pedal can carry out a pedal travel and, on the other hand, when there are functional disturbances of the brake pressure control device, at most with a slight idling path of the brake pedal, by the operation of the brake pedal in the master brake cylinder and the wheel brake cylinders, a brake pressure can be generated in a conventional manner.
