[CChase86]

I am posting this for my father, so keep in mind that I don't know how to describe everything in perfect detail.

He has a 1984 944. About two years ago he went out to the car one morning and the clutch was on the floor. The clutch slave cylinder had died. It was brought in to a mechanic who replaced the master and slave clutch cylinder. Everything was fine until...

Last week he went out to the car, got two miles from home and the clutch pedal went to the floor. However, the different part of this is that he could pull the clutch pedal back up, and it then worked normally for a while, when it did it again.

After bringing it home, we both looked at it, and you can pump the clutch in and out many times, then it will suck itself to the floor. It's almost like it is spring loaded to the floor. So, he had me look around at everything. There are no leaks, or signs of leaking anywhere along the lines or at either of the cylinders. There is a preload spring for the clutch, which also looks fine. The fluid level in the reservoir is fine. We bled the entire system the other day, and there is no air (there wasn't before either).

The thing with sucking itself to the floor is that it isn't even constant. I was in the car pumping it trying to make it fail, and occasionally I could actually make the clutch almost "drop" into the halfway engaged position, too.

I can answer more questions if I get them, or ask him, but we are at a loss for why this would be happening (especially given that it doesn't happen every time or even often).

Thanks in advance...
