The clutch on my 75 has been slowly dying for over two years and finally gave up a month ago. When I pulled it out it was exactly as I suspected; the 'fingers' were almost all broken except two that were ground down. The thrust bearing was also kaput. Even on its deathbed the hydraulics felt good however.
I had a spare clutch in good condition so I gave it a refresh (clean and new bearings) plus a new thrust bearing and rebuilt slave cylinder and have put the car back together. However, the pedal felt a bit soft and wouldn't quite return on its own. Thought I'd try it and no surprises that I couldn't select a gear. Bled again and now the pedal feels good. However, I still can't select a gear. Since bled again but nothing: no air and no improvement. The fluid is a little murky and so I'm thinking maybe the master cylinder has died but if that is the case would the pedal feel good? And why would it fail if it was working perfectly well before it came off the road? I was careful and don't believe I have allowed air to get into the master cylinder and REALLY don't want to change the master cylinder again if I can help it.
Any thoughts?
