To change the master cylinder on a 1993 Chevy Cheyenne 1500 pickup with a hydraulic clutch, first, disconnect the negative battery terminal. Then, remove the clutch fluid reservoir cap and drain the fluid. Unbolt the master cylinder from the firewall, disconnect the push rod from the clutch pedal, and remove the hydraulic lines. Install the new master cylinder by reversing these steps, ensuring all connections are secure and refill the reservoir with the appropriate hydraulic fluid.
I'm pretty sure that is a hydraulic clutch, check and see if you have a resivoir under the hood for the clutch. If you don't then it is mechanical and then you can adjust it. Check owners manual
There is no adjustment on a GL1500 clutch.
If it is a manual transmission, yes.
On a 1992 Chevy 1500, the hydraulic clutch bleeder is typically located on the slave cylinder, which is mounted on the transmission.

Be sure to use the appropriate tools to prevent damaging the bleeder valve.
