Generate the hydraulic pressure that disengages your clutch with the Dorman - First Stop Clutch Master Cylinder CM640102. It installs as a direct-fit replacement for the 2006-2011 Chevrolet HHR, taking the place of a worn or leaking original clutch master cylinder.
In a manual-transmission hydraulic clutch system, the master cylinder is the pedal end of the circuit: pressing the clutch pedal pushes its piston, sending fluid pressure through the line to the slave cylinder so the clutch can be disengaged for shifting.
