RE: Replacing clutch master cylinder on 4000Q

I second that.  I found this out after buying a rebuild kit and
rebuilding my M/C on my '85 C-GT.  Shoulda looked at the pedal first. 
It's OK, though, since the M/C has new guts now.  Car's gone anyway...

I second that too, kinda.  As a matter of fact, I was so used to popping
the clutch pedal back up with my left foot (I was concerned with
possible drag on the clutch), that when I drove other sticks, I would
automatically try to pop the clutch pedal up after shifting.  Took me a
while to stop doing that.  Oh, the relief when it was fixed!

I didn't do that.  On mine, it was the clevis itself, so even that is
not hard enough.  I bought a new clevis from the dealer.  It was either
$7 or $14 bucks.  I thought it was reasonable, being a factory part from
an Audi dealer, so I bought it.  I left the pedal in, too.  If worn too
far, however, it will wear the pedal itself.

It oughta help someone.  I just noticed that I wasn't alone when this
happened to me, and was compelled to post.  Mi Hermanos!!

Later,

rebuild the damn thing AND replace 	all the seals, since it's takin' so
freakin' long! (-:  )
