Seems to be confusion here.... The clutch has its own master cylinder which is bolted to the firewall with a slave cylinder attached to the bell housing on the passengerside. The clutch "system" has nothing to do with the brake system. The brake system has its own master cylinder which is bolted onto the booster. Both use the same fluid DOT 3 brake fluid. The bleeding process is the same for both systems.

If the reservoir was empty, the fluid went somewhere...

Find out where it went... Either a bad master or slave is letting it all out.

Lets see, your truck is a 94, that makes it thirteen years old. The clutch system is more then likely the same age. I would go with OEM parts.

This place has pretty good prices on OEM parts:

You guys are truly a wealth of information. I'm going to check it out today - see if any fluid has leaked out anywhere and also see how the clutch pedal feels and whether I can shift or not. If the reservoir is empty then I know I need to replace parts right away. If it's still full, I'll try bleeding it and see what happens. Either way, though, I think for long-term peace of mind, I'll end up replacing both the master and slave. Prices don't look that bad and the work seems easy enough to do. Thanks for all the advice. I'll keep you posted on my progress. Here is a pic of my truck. Not even 130k on her.
