Split the M/C from the booster & check the clearance between the bottom of the "thimble" recess in the back of the piston to the rounded nub on the end of the pushrod, want ~1/8".



And what does this tell me if it doesn't measure 1/8", Bob? Is the pedal overextending or depressing to far? Seems to me like the booster is becoming a vacuum. When the pedal sticks after dressing it, why does the engine jump in RPM's? If the booster is sucking, wouldn't this cause the engine to be put under a load? I am at a loss.
