Hydraulic Clutch

It is hydraulically operated clutch linkage. It is used when the clutch location makes it difficult to run a rod or cable to it. Hydraulic clutch linkage is also used in the high performance engines. These have strong springs in the pressure plate assembly and would require high pedal effort. Operation of the hydraulic clutch linkage begins when the driver depresses the clutch pedal. This forces the push rod into the master cylinder. Then the fluid with high pressure is forced from the master cylinder, through a hydraulic line, to a servo or slave cylinder. Here raise the question what is servo? A servo is nothing but it is a device which converts hydraulic pressure into mechanical movement. When clutch pedal is depressed, hydraulic fluid flows from the clutch master cylinder to the servo. The fluid pushes the servo piston out of the cylinder. This forces the release bearings and disengages the clutch.
