I've got a 97 f-150 xl everything was checked out a month ago and everything was fine, yesterday i was driving and the clutch lost all pressure and couldn't change gears. I checked the clutch master cylinder and there was no fluid. This is obviously the problem right? I've tried bleeding it but can't get any pressure back, is there any techniques I should try? Thanks

 

Blown slave cylinder. Happens alot when you put a new clutch in and don't replace it.
