  Q: How to service and repair the Clutch Master Cylinder on Chevrolet Suburban 1500?

  A:

  Begin Clutch Master Cylinder service by obtaining the clutch line removal tool (J 42371) along with other needed equipment. The Clutch Master Cylinder can be found on the engine compartment dash panel where turning it 45 degrees counterclockwise will help to unlock it. Start by disconnecting the wiring harness from the Clutch Master Cylinder start switch and pulling out the master cylinder from its positioning in the dash panel. The clutch line removal tool (J 42371) disconnects the clutch line from the concentric slave cylinder while the two clips securing the clutch line to the dash panel must be removed when replacing the Clutch Master Cylinder. The installation process requires placement of the new Clutch Master Cylinder into position then fixation through the two dashboard clips. Attach the concentric slave cylinder to the clutch line using the pullback action on the connector sleeve before placing the Clutch Master Cylinder into the pedal bracket's clutch pedal square hole. After ensuring the master cylinder is locked at 45 degrees clockwise, push the clutch pedal down and perform three release cycles to verify correct operation.
