Default Re: How does a slave cylinder go out?

Fetch, When the slave cylinder fails, the clutch won't release anymore. Your small leak probably just became a big leak and drew air into the system which means no more hydraulics to work the clutch. Check the line from the master cylinder to the slave cylinder. It has a rubber section which can also leak. Inline Tube sells a replacement line for $45 or you might have one made locally.
These trucks are not complicated compared to new ones. Of course when you add years of caked on grease, rusty bolts & nuts, wasps & mud daubers etc. things can get a little challenging. An original GMC service manual is worth the money too.
