"I rarely find the optimist intersects with the realist."
Boy, isn't that the truth. Then folks like to refer to those that are realists as being "negative."

Excellent Eric! Glad to finally hear a story directly from an anointed one
that appears to have been *blessed* by the Audi gods. After 20 years of working
on Audis Eric, I prefer 'realist' to any optimism or pessimism label. The
optimist says it's fine, the pessimist says it can't be, the realist says pray,
then just do the work necessary to get the job done right. I rarely find the
optimist intersects with the realist.
Thanks for reporting back
SJ

Always the optimist, eh Scott? You know I have high respect for your
considerable experience, so I took a close look at the slave while waiting for
the new cylinders to arrive. As I wrote before, I had to hammer on the rod to
free the piston. The piston was then free enough to push it in by hand, but
when released it came to rest several mm inboard of the circlip. A light
application of the clutch pedal pushed the piston to the end, but it was again
frozen in place until whacked with great force. I noticed a slight bit of
corrosion/grime on the outermost section of the bore, and tried to clean it as
best I could. That, and some exercise of the piston by hand, seemed to get full
travel back, although there was still a hint of stiction.
Figuring that I didn't have much to lose (except the possibility of ruining the
friction disc if the slave barfed fluid), I popped the slave back in place and
went at it with the pressure bleeder. I got lots of nasty fluid (looked like
liquid graphite). Clutch operation seemed to be back to normal, so I took a
short test drive. It worked OK at first, but then it felt like it stuck briefly
(release pedal, clutch stayed disengaged very briefly, then engaged abruptly),
so I parked the car and waited for the new parts.
Yesterday I replaced both MC and SC. Didn't have a chance to drive it until
today. I did around 100 miles in the local twisties, including several WFO
pulls in 4th gear up steep grades to test clutch clamping force. Lots of
shifting up and down, stop and go stuff too. I'm glad to report that it felt
normal the whole time. I'm hoping it'll stay that way, at least for the near
future.
