I AM THE ORIGINAL OWNER OF A 2002 CHEVY 2500HD PICKUP WITH 65,000 MILES. I EXPERIENCED A TOTAL FAILURE OF THE BRAKE SYSTEM ON 28 AUG 2010 DUE TO A RUPTURED BRAKE LINE. THE LEAKING LINE WAS IN THE VICINITY OF THE DRIVER'S DOOR AND ALL LINES WERE HEAVILY CORRODED. LEAK WAS LARGE ENOUGH TO FULLY DRAIN THE BRAKE FLUID RESERVOIR. FAILURE HAPPENED WHILE PARKING TRUCK AT HOME. NO ACCIDENT OCCURRED, BUT I WAS LUCKY. THIS FAILURE COULD HAVE CAUSED A FATAL ACCIDENT. REPAIR OF THIS DEFECT WILL REQUIRE REPLACEMENT OF ALL BRAKE LINES ON THE TRUCK. IN MY OPINION, THE ROOT CAUSE OF THIS BRAKE FAILURE IS A POOR CHOICE OF MATERIALS (PLAIN STEEL) FOR THE BRAKE LINES. CHEVY SHOULD HAVE USED A CORROSION RESISTANT MATERIAL. *TR
