Brake pedal going to the floor suggests you have either a leak in the system or master cylinder failing to create pressure. If the fluid isn't being lost, I would go for a different master cylinder.

Yep, the hydraulic pressure goes somewhere to a dead head regardless of the prop. valve. Leaking back through or air getting into the system somewhere.
