I've been working on my Fiero's clutch for a few days now, both using pedal and vacuum bleeding to try to get the clutch to work, and finishing it off by pushing in the slave cylinder rod. Vacuum bleeding seemed to work, and I was able to get approximately an inch of travel out of the slave cylinder rod, not enough to go into gear, but in the morning the master reservoir is empty and the pedal has no pressure whatsoever. I checked in the common problem areas - the master cylinder boot and where the lines screw in to the clutch cylinders, but I couldn't find signs of leaks or loose fittings, and the clutch pedal is a bit depressed, but I don't think bent enough to cause an issue. When I bought the car it had been sitting for 23 years under a tree, parked because of a broken master cylinder rod but it had still had fluid in it then. Since then I have replaced the clutch master and slave cylinders and bled the system many times but it has not seemed to work. What would be good things or areas to check?
