The invention concerns a fluid pressure actuation system, in which a piston (13) moves in a master cylinder bore (12) under the operation of a pedal (15) to displace hydraulic fluid from the bore to actuate a function, a sensor (27) senses the position/movement of the pedal, an electrical actuator (25) is directly mechanically connected with the pedal or another component connected with the piston (13) of the master cylinder, and an electrical control means (26) is provided which receives signals from the sensor and applies a controlled output to the electrical actuator (25) to provide direct mechanical assistance to the movement of the piston dependent on the pedal position/movement, a rod (30), connected with the master cylinder piston, projects from the master cylinder and the electrical actuator (25) operates directly on this rod to assist the movement of the piston within the master cylinder bore, whereas the rod projects from the other end of the master cylinder from the end from which the actuation rod (14), which connects the pedal to the piston projects. |
