<p>The invention concerns a vacuum brake booster comprising a casing (1) housing a piston (2) with a membrane subjected, during braking, to a vacuum amplifying the braking force controlled by the action of the brake pedal (10) and acting on the master cylinder, the brake booster piston (2) being linked to a push rod (8) acting on the master cylinder piston and to a control lifter via a reaction disc (11). The end of the push rod (8) is connected to the reaction disc (11) via a sensor (15) supplying an electric signal when an actuating force is applied by the control lifter (9).</p> |
