    It happened twice now. While driving the clutch pedal would slowly lose tension. Eventually has nothing at all and goes straight to the floor. Park the car for a few minutes and it pumps back up. Stays fine for month or so. Master is not keaking fluid and seems to not have any air ? Any thoughts or ideas?

    No way for the slaves to go down without losing fluid out the cylinder. If no fluid loss, it is the master.

    Same thing happened to me. Twice. The first time it was the slave cylinder. The second time it was the master.
