Brake line failure from rust on a vehicle with less than 82,000 miles on it. all the lines must be replaced. failed in moderate speed in major traffic jam. second failure on same vehicle. after first failure all line were inspected and no problems were noted. apparently without performing an ultrasound thickness analysis it is not possible to determine the condition of the brake lines.
Sitting at a traffic light, and the brake pedal went to the floor, allowing the truck to roll into the intersection. the only way i stopped it was shift the transmission into neutral. i nursed the truck back home and found all of the brake lines are corroded with one blown out. the master cylinder was almost empty in one chamber. the other chamber was totally empty. truck has only 28,000 miles. *tr
