[urq] UPDATE - Clutch Slave Problem?

[urq]

By any chance did you replace the clutch hose that goes from the slave to
the end of the metal line at the firewall?  I'd bet that "liquid graphite"
fluid came from the inner walls of the flexible line ...

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.
