The truck does not stop when the brakes are applied. The pedal goes to the floor. It will pump up to about half a pedal with 3 or 4 pumps, but will go back to going to the floor after less than 30 seconds. The pedal goes to the floor rapidly with no resistance.

Something in the MC is bypassing (even though it is new) or you have a rubber brake hose that is expanding. Also, make sure the rear brakes are properly adjusted and the brakes were properly bled. Check for any leaks too expecially the flex hose to the rear axle.
