Hello all,
  I've twice recently experienced "soft pedal" on my clutch, once it just felt 'weak' but I didn't
have any problems shifting or starting out.  Once, the clutch was not doing it's thing
properly..Then, after a few minutes of downtime..a trip into a store or a few minutes on the
computer in the parking lot and it goes back to perfect operation..What the --?  I have fresh brake
fluid..a month or two old.  I have the proper level.  My brake master cylinder is relativly new and
when that was replaced, I bled the clutch slave properly.  The clutch has been good since that brake
MC replacment(about 6000 miles ago)..no problems except at odd times, this weird "air in the clutch
cylinder' behavior that soon goes away again.
  Is it time to replace THAT now?  Why the intermittent missbehavior?
  Thanks in advance...
