The invention relates to a hydraulic control device consisting of housings containing master cylinder(s), slave cylinder(s) and cutoff valve(s). The housing 1 contains a master cylinder 2 whose piston 4, controlled by the lever 7, injects the compressed liquid fluid - via the pipe 28, the gate valve 11, the pipe 29, the rod 23 and the piston 22, which are pierced - into the cylinder 21. The slave cylinder has a valve 24 for filling and topping up. Pressure on the lever 7 pushes the piston 4 which compresses the fluid in the master cylinder 2 which is transmitted to the slave cylinder which moves under the action of the pressure and operates the pedal 20. The closing of the hinged cover 12 of the housing 10 causes the gate valve 11 to close, interrupting the circulation of the fluid, and locking the slave cylinder 21 in the desired locked position. <IMAGE>
