ABSTRACT:
A brake system has a first piston (2) which is coupled to a brake pedal (3), a second piston (4) used to actuate a master cylinder (1), a third piston (5) actuated by the first piston (2) and movable into a force-transmitting connection with the second piston (4), and a pedal travel simulator. The first and the third pistons are coupled depending on the displacement of the third piston (5). The pressurization of a space (11) between the second and the third piston loads the second and third pistons (4, 5) in opposite directions. A pressure-supplying module (13) enables both filling and evacuation of the space (11) as well as its evacuation. A fourth piston (8) between the first piston (2) and the third piston (5) delimits a hydraulic compartment (9) in interaction with the third piston (5). A valve assembly (10) varies the pressure introduced into the space (11).
