Abstract: A system generates a brake pressure with a pump which delivers a volume into the chamber of a master brake cylinder and builds up a pressure which is used by at least one additional assembly, particularly a power-assisted steering system. The system has at least one distributing and throttling element for admitting a definable pressure to the chamber of the master brake cylinder and/or the additional assembly. The one or more distributing and throttling elements can be triggered, as a function of the brake pedal position and/or of driving condition values and/or of operating values of the vehicle, such that the chamber and/or the additional unit can be acted upon by a pump generated adjustable pressure.
