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!!
Ken (Maybe this Sunday I pick up my q! Allan: you may as well just
rebuild the damn thing AND replace all the seals, since it's takin' so
freakin' long! (-: )
