When a worn or leaking clutch master cylinder leaves the pedal feeling soft or makes shifting difficult, the Dorman - First Stop Clutch Master Cylinder CM39598 supplies the hydraulic pressure that disengages your clutch. It drops in as a direct-fit replacement for the 1984-1987 Nissan 200SX (L4-1.8L), 1984-1988 Nissan 200SX (L4-2.0L), and 1987-1988 Nissan 200SX (V6-3.0L).
The clutch master cylinder converts clutch-pedal movement into hydraulic pressure, pushing fluid to the slave cylinder so the clutch can release. If a failed master cylinder is the cause of a soft pedal or hard shifting, this unit is designed to replace it.
