I have replaced all lines, rear calipers, and master cylinder, and pedal is very soft. The brake pedal will firm up when pumping a couple times when truck is off but as soon as you start truck pedal to floor. My mechanic has had it for 10 days and can not for sure it out! ANY HELP PLEASE!

What kind of mechanic are you dealing with? This is BASIC car tech, not rocket science. Air in system = Spongy brakes.
