Brake problems

[nasty71]

Break problems my 1971 has problems stopping 4 wheel disk changed booster master cylinder and pro valve, works ok for a while, then after 4 weeks or so breaks go too floor . It seams too me the pro valves are junk.Would like too switch over too Wilwood any suggestions???

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.
