2001 GMC Yukon XL 1500 Clutch Master Cylinder

The procedure is to locate the clutch master cylinder on the dash panel, quick-connect the hydraulic line to the master cylinder, push the clutch pedal down all the way and squeeze in the tabs, turn the master cylinder 45 degrees counterclockwise to unlock the master cylinder, disconnect the wiring harness, and remove the clutch master cylinder and the clutch master cylinder.

The proper way is to ensure the reservoir is filled to the fill line with new brake fluid, push the clutch pedal all the way down to the floor panel, open the bleed screw on the clutch actuator, close the bleed screw, release the clutch pedal, repeat steps 2, 3, and 4 until all the air is out of the clutch system, pump the clutch pedal very fast with full strokes for 30 seconds, and stop pumping and let the air escape into the reservoir while moving the rubber pad up and down 12 mm (0.5 in) for 30 seconds.

The proper way is to install the master cylinder, turn the master cylinder 45 degrees counterclockwise to lock the master cylinder, connect the wire harness to the clutch master cylinder, make sure the pushrod bushing snaps into place to ensure proper clutch pedal operation, and quick connect the hydraulic line to the master cylinder.
