Same thing I had. If I remember there wasn't enough switch adjustment. When you replace the master with a new or rebuilt unit exactly the same as the one you took out and the pedal won't return it is frustrating. I should have rebuilt my original master. :BangHead::BangHead:
Thinking of doing that same thing, the old M/C was leaking into the booster, that's the reason for replacement. New parts from suppliers are always a crap shoot.
