Also, put a new brake master in and bled the lines best i could and the pedal seems fine until it sits overnight, then goes almost to the floor until I pump it twice. Is this somewhat normal on these big trucks?
No, it's not normal to have to pump the pedal to get the brakes to work. Have you adjusted the brake shoes? If they are out of adjustment it takes extra fast pumps to send enough fluid to get the shoes to engage. You want to have the shoes dragging when turning the wheel by hand.
