Thank you Michael.
What I did not say is that the present primary and secondary clutch
hydraulic cylinders have been on the car for many years and, up until
recently, functioned just fine. The change in pedal performance/actuation
probably "accumulated" and happened gradually in a way that I either did
not notice or I felt to be acceptable, and only when I drove the car after
a few months' inactivity did I feel there was a problem. Since the clutch
itself had a good many miles and years on it I thought I would start there
and though installing a new pilot bearing, disc and (annular) pressure
plate brought the pedal up a bit it, full actuation/disengagement from the
flywheel is still too close to the floor for my liking.
I'll probably give the system another good bleed and depending upon the
outcome I may be following up on your suggestions.
Best--Michael Oritt
