Abstract: A braking force generator includes a primary piston displaceable in a housing to enclose a primary pressure chamber. A pedal simulation device is connected to the force input element. A pedal actuation detection device detects the pedal actuation and an actuating force booster stage. During normal operation the force input element is mechanically uncoupled from the primary piston, and the actuating force booster stage exerts an actuating force on the primary piston. In the event of failure of the actuating force booster stage the force input element is workingly connectable to the primary piston such that a contact extension extends from the primary piston towards the force input element. During normal operation the contact extension is held by a release gap at a distance from the force input element and in the event of failure of the actuating force booster stage the force input element after travelling the release gap is applied workingly against the contact extension.
