Dorman - First Stop Clutch Master Cylinder P/N:CM640227
Press the clutch and this Dorman Clutch Master Cylinder (CM350105) turns that pedal effort into the hydraulic pressure that disengages the clutch. It drops in as a direct replacement across the 1996-2005 Chevrolet Blazer, 1996-2004 Chevrolet S10, 1996-2005 GMC Jimmy, 1996-2004 GMC Sonoma and 1996-2000 Isuzu Hombre.
The clutch master cylinder feeds the slave cylinder each time you push the pedal, so a worn unit can show up as a pedal that sinks or feels spongy, fluid seepage, or trouble disengaging the clutch. If a leaking or failed clutch master cylinder is the cause, this unit replaces it. Diagnose the cause before replacing.
