An assistance piston (150) freely advances with respect to the actuator piston under the thrust of a control rod (170) for actuating a piston (111) of a master cylinder (110) in case of failure of an electric brake booster (120). A return spring (163) is arranged between the thrust flange and the actuator piston.",
