Last evening the clutch went to the floor, had to use my toe to pull it back up and still no pedal. Cant shift. Pulled the slave cylinder and was dry and no obvious leakage. There were no telltale signs of anything wrong, all happened all of a sudden. Short of a bad master clutch cylinder what would have to go wrong with the clutch itself. Is there a return spring on the fork, do the forks break? Any insight would be helpful.
