Patrick:
   A quick update on my brake problem.  I installed a used "bomb"
yesterday and it DID NOT change a thing with my 89 brake drag.  After 5
miles of slow speed neighborhood travels, the car slows down as before,
with greater engine effort required.  You can see the boost turbo gauge
actually go up from .4 to .6 when travelling @ 30 mph.  The used bomb
reguires a much sharper pedal stab to get the light to blink and after
engine shutdown, 20 pumps seem to be there inreserve.
   We had a bitchin' storm here in Mpls last night.  My basement carpet
got soaked as gutters overflowed when 4" in half an hour came down.  The
car will probably sit for another day as drying out the mess takes
priority.  Let me know if any of your tests proved anything.
