Most of the time the clutch pedal acts completely normal.
Sometimes if I just nudge the pedal it will take off on it's own about 3/4 of the way to the floor.
It never has gone beyond the point at which I can't get a toe under it, although I know that the pedal can do this if the hydraulics have completely failed.
I had to replace the clutch master and slave cylinders a few years ago- they could be about 5 years old now.
As soon as I lift the pedal back up again it's normal. It doesn't seem to matter what's going on with driving- how long it's been since the last pedal push (overnight, for example). Once it acts normal then I can jump all over the pedal and it stays normal, though.
I'm going to try bleeding it out and also look for leaks, but there's plenty of fluid in there.
