General Question (mAC) Pressure Plate Failure

[Phil Haag]

Hello,

Yes, I have a '90 200 Quattro Avant.   I am having the same problem, and 
will be installing a clutch kit this afternoon.  Mine started with a noisy 
release bearing, aka through out bearing.  Now when I step on the clutch I 
get a loud screeching, whirring sound, and sometimes the clutch peddle stay 
on the floor, and I have to pull it up with the toe of shoe.

I think the problem is a shot pressure plate and bad release bearing.  The 
disc still holds tight, just the pressure plate fingers and bearing, are 
bad.  Well I'll know for sure in a few hours.

Phil
