so i hopped in my car this morning and pressed the clutch in to start and it went to the floor... sucky. i grab a bottle of brake fluid i have and go to top it off but there isnt any fluid missing. i pump the pedal and it regains pressure. drive off to work and i would have to pump the pedal every 5 miles or so or i loose pressure again. at lunch i come out and still all fluid is there and i dont see any leaks. i bleed it anyway. repeating the procedure about 10 times and it feels nice and firm again. then on my way home i lost pressure again.. so what broke? i have full fluid and its not discolored. i dont see any leaks and it seems to be holding pressure better but i dont want it to stick me somewhere. ideaS?

Could be a master cylinder problem. I think I had that same problem, so I ended up replacing both master and slave cylinder. Problem solved.

Yep, most likely the seals in the master are leaking by.

Yes, it was my master and I decided to replace the slave while I was at it. I also installed a braided stainless steel clutch line, too.

Check the slave. Its located on the top of the transmission and with 2 bolts its comes off. I had the same issue and I thought it was the entire slave. Just check the cylinder inside the slave and see if it has a good seal. The replacement is like $8 at autozone and it fixed it for me.

I had the same problem going on... pedal would go to the floor and not return, but only after I had the car parked up for a good 4 days or so. I'd pump it up and she'd feel fine again.

Just replaced my slave cylinder this morning. I couldn't see the leak until REAL close inspection but the fluid was slowly coming out from inside the little boot that covers the pushrod. Pedal now feels MUCH better..

yeah ill probably replace both and try to find a braided hose. strange thing though.. my pressure is now sustaining and i dont have to pump anymore. still not taking any chances though.

by the way. i think i want to paint it. any pics of first gen scca or nasa race cars laying around you guys want to post?

I got my braided line off of eBay. I think it went for $30.
