MGC BRAKES

[Mike Razor <mrazor@kih.net>]

  Put new boosters on the MGC Bled the brakes, got a bunch of
nasty black brackish fluid out of the system.  Went for a
drive got about 100 feet up the road and the brakes locked up
tight as a drum, across the south bound lane.  Could not get
it to budge, called a tow truck who dragged it on the back and
out to their shop.  The response there was "I Dunno" may be
the M/C  gone bad.
Any suggestions?
