"If you read the posts, even though they were pulling brake fluid through the front bleeders the wheel cylinders were dry. Why? Because the front of the master cylinder was not pushing fluid into the lines. Without fluid, there is no hydraulic pressure. With no hydraulic pressure, the pedal goes to the floor."

This logic is severely flawed. Piston in block moves over and there is no flow. That would make the pedal hard not soft. That's one of the problems with this theory, it doesn't hold fluid!!
