Thanks guys!! I spent all afternoon making sure the brakes were adjusted out properly……then re-bled the brakes 3 different times. Right rear, then left rear, then right front and left front last. Used an ez-bled system on it. Still no brakes. If you pump them several times, you get a pedal and it’ll stop the truck. But next time, the pedal goes right to the floor. Could it be a bad master cylinder. Even though it’s new, could a defective unit cause this?
