Having this issue w/ my clutch that I thought I fixed last year.
What its doing: When using the clutch to start/stop, or just resting your foot on the clutch pedal with medium pressure, the clutch loses resistance and the pedal falls to the floor....and if its in gear the clutch will engage super close to the floor.
Then just letting go of the pedal, it will build pressure back up and will feel normal till you use it, or hold it in for too long.
It did the same thing about a year ago, and after rebuilding the slave, and replacing the master cylinder w/ a unit from autozoneit was fine. But now its doing it again. I replaced the slave yesterday, and after bleeding the clutch...and there is NO AIR in there...still doing the same thing. There are no external leaks anywhere.
Tired of this...could it be anywhere else in the clutch system that could be causing this? Should I take the master cylinder back under warranty and replace it again too?
