On Friday I was at the dump with my 02 Dakota. As I went to pull up to leave the brake pedal went to the floor. I had replaced all but 1 brake line during the past few years. It was up above the rear diff and kind of out of site. Scary thing was my Son took the truck on a 45 minute each way trip to drop off some stuff for his friend last weekend. I can't get it out of my head what could have happened. Jim
