If the pedal goes to the floor, and the fluid doesn't move in the MC, that
tells me the MC seals are blown internally. I believe that particular MC is
the very devil to rebuild (if it's the one I'm thinking of), so I'd just go
ahead and get a new one.
This may not be your only problem, by the way, but it's a start <g>.
