964 - No Clutch Pedal
#16
Nordschleife Master
It was the clutch slave cylinder.
(I'm laying odds on that for yours.)

agree with elbeee964 that it's probably a problem with the clutch slave cylinder. The sinking pedal has been known to happen when bleeding the slave. Sounds like you might have gotten an air bubble in the slave somehow when you jacked up the car. Now that the air bubble has disappeared, for whatever reason, clutch pedal is back to normal.

Have you checked the level of brake fluid in the reservoir? The clutch master takes brake fluid from the same reservoir, but at a higher level. It is designed to fail first as a prelude to brake problems. I didn't see any mention of you checking the reservoir in the trunk. I'd be sure to do that first.

Thanks everyone for the assistance with this problem. After pulling on the pedal (which returned it to it's normal position) I drove around aggressively stopping and starting to see if any change would occur. Nothing abnormal detected. Decided to attend the Auto X as planned but watch out for any lingering symptoms. Had a mechanic friend at the track look over the system and make a determination and he thought a couple of scenarios;
1. Air bubble in the system.
2. Roll pin broken or failing.
3. Clutch master/slave cylinder needs replacement.
Everything that was suggested by fellow 'Rennlist' members and I thank you all. Now I will go through the car from the 'roll pin' first, then to the 'master/slave cylinders' and see where this problem is.

"Indycam" your input was valuable, along with the other 'Rennlist' members who gave their suggestions. The car ran with no issues during the Auto X. I'm still going to have a look at the 'roll pin' and see what that's all about (more curiosity than ever but piece of mind also) and then address the Clutch Master Cylinder next. Might be time to replace it as well...

It was a very smooth pedal return to the normal position, with no grinding or scraping. What is your thought pattern for asking about smoothness and grinding?

If it were a roll pin problem and you lifted the pedal and it started to work again , its unlikely that just a smooth , no grind , would set the roll pin right .

The culprit was found yesterday and it's a leaking 'rubber hose' (at the connector) going to the Clutch Master Cylinder. I have not looked into the 'roll pin' as yet but will be disassembling the pedal cluster this weekend to inspect. Just for piece of mind, as it's been discussed and I new nothing about it...
Thanks for all the assistance...
