When your clutch pedal turns soft or stops building pressure, the Dorman - First Stop Clutch Master Cylinder CM39763 is the hydraulic component that turns pedal force into the pressure needed to disengage the clutch. It drops in as a direct-fit replacement for the 1989-1996 Chevrolet Corvette (V8-5.7L), sending fluid to the slave cylinder each time you press the pedal so you can shift gears.
A soft, spongy, or sinking clutch pedal, hard shifting, or hydraulic fluid seepage can be signs the master cylinder may need replacing; diagnose the cause first, since other parts can produce the same symptoms. If a failed clutch master cylinder is the cause, this unit replaces it. Country of origin: China.
