Zusammenfassung:	PURPOSE: To achieve the optimum brake force distribution usable to closed loop anti-block control and closed loop drive slip control, and economically achieve favorable function characteristics by providing a means such as a pressure modulator provided in a brake circuit. CONSTITUTION: A brake pressure actuator is composed as a pressure modulator 14, an output pressure chamber 12' of this movably defines the boundary with pressure seal by a piston 39' relative to a drive pressure chamber 41', and it can be connected to a brake circuit II on one side, while it can be connected to an output pressure chamber 26 of a brake system 21 on the other side. Pressure rise in the brake circuit II is achieved by valve control pressure charge in a drive pressure chamber 41' using output pressure of an auxiliary pressure source 44. Pressure rise in the brake circuit II is realized by servo control, and as an ideal value for this, a set point for prake pressure in the brake circuit II connected to the pressure modulator 14 is used as a reference value with relation to brake pressure in the other brake circuit I.
