As the saying goes, there's no such thing as a dumb question :)....With the master cylinder disconnected, should my brake pedal hold firm or go to the floor.

Thank you, that helps and makes perfect sense. I'm puzzled because I'm on my second master cylinder, both bench bled and pedal still goes to the floor. I guess I'll disconnect the two master cylinder ports and see if my brake pedal holds firm. Thanks again
