Hi, I have a 2007 gt. 40,000 miles. As title says, will be driving just fine and go to shift or come to a stop and the pedal goes straight to the floor. Pull it back up (just 1 time) and the next push of the pedal is 100%, there is no "pumping up" required. I have not been able to repeat it or do it on command. Fluid is full and no apparent leaks. Clutch engagement/release is just fine when it has the pedal. But occasionally go to push pedal and its gone. Thoughts in my head offer reasoning it could be either the clutch master cylinder or slave cylinder / throwout bearing, wondering if anyone else has experienced this issue since both involve a fair amount of work would like to guess right the first time I am personally leaning towards master cylinder though

also, when the clutch is disengaged. have not noticed it to "bleed off" at all. the problem is only on that initial push of the pedal when it does act up.

Slave cylinder and TOB, all one piece on our cars. Mine had the same thing a few days ago and it now in the shop getting replaced.
