An actuating device of a brake system controlled by a brake pedal and/or a brake management system for supplying brake circuits with pressurized brake fluid includes a master cylinder, an electric motor, a ball/nut screw transmission, a nut, a screw, and a free connection rod. The master cylinder is connected to the brake circuits and has a primary piston. The electric motor is controlled for a braking action. The ball nut/screw transmission is configured to transform rotary movement of the electric motor into a translational movement of the primary piston. The nut is blocked from moving in translation, free to rotate, and driven by the electric motor. The screw is free to move in translation but blocked from rotating. The free connection rod is pressed between a base of the primary piston and the screw in order to transmit a thrust of the screw to the primary piston.
