tracking down a clutch problem...

[berbes]

back in may, i went out to the car ('95 325i which i swapped out auto for manual summer '05), and the clutch went right down to the floor. thru posting here and elsewhere, it seemed the best bet was the slave cylinder. i ordered the part, meanwhile i added brake fluid, pumped, pumped, added more fluid, pump, pump, etc. until i got the pedal back. i never installed the slave, as i never had another problem with the pedal, plus i didn't notice any fluid on the driveway.

i drove the car everyday until i just went out of town this weekend for 4 days. came back, and i lost maybe 70% of the pedal. had to do the drill again, just not as bad.

what could possibly be the problem? a small, small leak that wasn't apparent until the pedal pressure had the chance to subside by sitting a while?

leaks are not apparent, but i know that means nothing.

ideas?

thanks, guys!

Hydraulic clutches can take in air without leaking and I would always change the master and the slave as a pair, because if you change one it will increase the pressure on the other and very often blow it.
