A brake system with at least one brake circuit comprises a mechanical brake-pressure control device and an electrical brake-pressure control device. The brake system is constructed without additional expenditure and by use of a mechanical brake-pressure control device and by an electrical control valve device. The system is constructed such that the brake-pressure modulator (8) of the electrical brake-pressure control device (6, 8, 11, 19) can also be controlled by pressure. The brake-pressure modulator (8) meters the brake pressure, both on the strength of the supplied electrical signal as well as according to the value level of the fed-in redundant brake pressure. The control electronics (11, 19) of the electrical brake-pressure control device (6, 8, 11, 19) is constructed such that it sets the strength of the electrical signal to a value required for covering and for meeting the respective brake-pressure demand request. The invention structure can be employed preferably in connection with road vehicles and motor vehicles.
