Braking system comprising a brake booster with electric motor driving the push rod of the piston of the master cylinder via a ball-screw connection and actuated by a control rod. In the casing connected to the master cylinder, the brake booster comprises an actuator piston guided in translational movement by at least two guide pins which are parallel to the axis of the master cylinder and which is driven in translational movement by a ball screw of which the screw, driven by the motor, is offset with respect to the axis of the master cylinder. The screw collaborates with a nut translationally as one with the actuator piston, and a bore of the actuator piston receives a boost piston equipped with a reaction disc and with a plunger piston connected to the control rod.
