A leaking or failing clutch master cylinder can rob your clutch pedal of the hydraulic pressure it needs — the Dorman - First Stop Clutch Master Cylinder (CM39820) is a direct-fit replacement that converts pedal effort into the fluid pressure that disengages the clutch. It drops in for the 1991-2003 Ford Escort, 1990-1994 Mazda 323, 2003-2008 Mazda 6, 1992-1995 Mazda MX-3, 1990-1998 Mazda Protege, and 1991-1999 Mercury Tracer (see the Buyer's Guide tab for the full engine list).
With a 0.625 in inside-diameter bore, this Standard Replacement-grade cylinder generates the hydraulic pressure that travels to the clutch release circuit each time you press the pedal. If a worn or leaking master cylinder is the cause of a spongy pedal or trouble disengaging the clutch, this unit replaces it — diagnose the cause first. Country of origin: China. Manufacturer part number CM39820.
