Abstract: A brake pedal simulator for a brake system of a motor vehicle has a chamber with hydraulic fluid which is limited by a first piston coupled to a brake pedal, a second piston having restoring means for producing a restoring force, and a third piston driving a pressure transducer. The first and second pistons are functionally connected together by the hydraulic fluid when a first valve is open to transmit the restoring force to the first piston upon movement against the hydraulic fluid. This first functional connection is interrupted when the first valve is closed. The first and second pistons are functionally connected together by the hydraulic fluid when a second valve is open to transmit movement of the first piston to the third piston. This second functional connection is interrupted when the second valve is closed.
