Have put 55 Chevy that I just put disk brakes on all 4 corners. Have new master and all new lines/hoses. There are times when pedal goes almost all way to floor, car stops but not abrupt. It will do it after sitting for awhile after driving or when I take it out of garage. Thinking about putting a one way valve between master and back brakes so fluid will be there and not take to much pressure. Any help would be appreciated.

Lotta things can cause this, air in the system, soft/swelling hoses, improperly installed or designed caliper brackets, wrong master or proportioning valve for four wheel discs, are some possibilities.

You can't use a check or residual vakve on disc. There is no return spring, so any pressure will keep the pads in contact with the rotor.
What rear calipers? If the emergency brake is adjusted incorrectly on some calipers, the pads will be too far from the rotor, especially after hand brake use.

Good point on the e brakes built into the rear calipers, they were somewhat problematic when I worked for Cadillac, especially if not used occasionally to keep them adjusted.
