Re: Clutch Pedal Noise

Mike,
>From your description it sounds like the rubber bellows on the clutch master cyl 
is the culprit.  Bet if you watched the process the bellows is compressing and 
slowly expanding when you release the clutch.  I'd also bet that there is a 
little fluid in it that is sealing up the air release that should allow 
reexpansion.  I've had the same experience with an 86TQ.  I'd also guess that 
the thump is the clutch arm actually hitting the rubber stop when the bellows 
finally lets go. The stop has become dry and noncompliant.
