In a combined booster and tandem master cylinder assembly (10) for a vehicle braking system an actuating piston (18) includes an auxiliary bore (30) in which works an auxiliary piston (31) coupled to the pedal (11). A chamber (33) defined in the bore (30) by the piston (31) is connected to a recuperation reservoir or through a one-way valve (34) and a restricted passage (35). The chamber (33) is adapted to be filled through the one-way valve (34) with fluid when the actuating piston (18) moves relatively away from the auxiliary piston (31) during"traction control" in order to provide an instantaneous pedal reaction with the one-way valve (34) closed, should the driver switch to a brake-applying mode. |
