The Dorman - First Stop Clutch Master Cylinder (CM39293) turns clutch-pedal force into the hydraulic pressure that disengages the clutch, and it drops in as a direct replacement for the 1980-1982 and 1987-1988 Porsche 924, the 1983-1991 Porsche 944, and the 1992-1995 Porsche 968 across their L4-2.0L, L4-2.5L, L4-2.7L and L4-3.0L engines. As the master cylinder in the clutch hydraulic circuit, it feeds fluid toward the slave cylinder or release mechanism each time you press the pedal. If a leaking or malfunctioning clutch master cylinder is the cause of a low or spongy pedal, this unit replaces it.
