Abstract
A hydraulic braking device comprising a master cylinder and a brake booster. The braking device comprises a control piston driven by actuating a brake pedal and mounted so as to be tightly slidable in a plunger of a piston of the brake booster. The control piston comprises a first end portion having a certain cross-sectional area and being arranged to cooperate with a gasket so as to establish, during braking, a modulated communication between the first chamber of the brake booster and a discharge chamber of the master cylinder. The braking device has an effective cross-sectional area counter-acting a pressure existing in a region comprised between a master cylinder piston and the control piston. Such area is different from the cross-sectional area of the first end portion of the control piston.
