Thanks Doyt and Marc.  The brake master cylinder is brand new. I just
installed it because of the dragging brake problem on all 4 brakes. I took the
opportunity to upgrade my G54s to G60s and went to the vented setup on the
back. I also put on new stainless lines. I think the brake and clutch problems
will fix themselves when I pressure bleed today. I was just curious about
bleeding the slave again....if I should reverse pressure bleed it or pressure
bleed from the reservoir ( I made a setup to pressure bleed using an air
compressor)? Also, only the front brakes are dragging. It's not as bad as when
the MC went bad, buit the fronts get smelly even on a short drive. I am not
sure if I installed the pads with the retaining clips correctly. Hmmm...I
painted the calipers before I put them on too. Could paint keep the pistons
from fully retracting? Again thanks for the ideas. I'm going to go try my luck
now.
