vary mushy brakes

[bbmonte396]

this is for a 81 Monte Carlo
Ok I am having some brake trouble. When I press the peddle it is vary mushy then it is rock hard car will stop I installed all new brake lines, rear wheel cylinders, calipers, 2-master cylinders and 2 brake busters the only thing that is old is the prop valve but I cant see that being the problem because if it is mushy where is the fluid going? Now I have bled the lines with 2 large bottles of fluid. Might there still be air trapped in the lines? If not am I going crazy!
I guess I am willing to remove the prop valve with an adjustable one. If I do that the adjustable valve will go on the rear line and the front line will just run in to the master cylinder? And what adjustable valve would I be looking for I know they are rated in PSI

P.S I bench bled the new master cylinder prior to install 2 x

what kind of wheel cylinders did you use? i had a similar problem and it was the new wheel cylinder was leaking, it was sucking air back into the system.
