Cadillac Repair: 1965 CADILLAC BRAKES, brake hoses, wheel cylinders

Question
My husband and I have tried several times to get pedal on our brakes and still no pedal at all. We have bled them, replaced the master cylinder, and not sure what next.

Answer
did you check all the wheel cylinders for leaks ?.

Are you losing fluid from the master cylinder ?.

Are the brakes adjusted correctly ?.

If neither, Then you most logical cause would be the equalizer valve the brake hoses or possibly a faulty master cylinder.
