NHTSA Complaint #10545340 — 2004 GMC SIERRA 3500

THIS PAST WEEK, AS I WAS DRIVING TO GET GAS FOR OUR CAMPING TRIP, THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR WITH NO WARNING. I WAS ABLE TO GET THE DUALLY SLOWED DOWN WITHOUT INCIDENT, BUT WAS IT EVER CLOSE. AFTER GETTING THE TRUCK BACK TO MY HOUSE, I BEGAN INVESTIGATING THE ISSUE AS I SAW NO LEAK AND THE RESERVOIR WAS NEAR FULL. I SAW ONLINE THAT THIS SEEMS TO BE A GM ISSUE WITH A FEW YEARS OF TRUCKS IN MY AGE BRACKET. I CLIMBED UP UNDER THE TRUCK AND FOUND THE LINES TO BE SHOT. NOT ONE WITH A RUST HOLE, BUT ALL OF THEM CORRODED FROM ONE END TO THE OTHER. I KNOW THE TRUCK IS 8 YEARS OLD, BUT IT SITS MOST THE TIME AND ALMOST ALWAYS THROUGH THE WINTER. I HAVE ONLY HAD ONE OTHER CAR IN 30 YEARS THAT HAD A BRAKE LINE RUST. IT SHOULD NOT BE HAPPENING IN THIS HIGH END OF A VEHICLE. MY DAD BOUGHT THE MATCHING TRUCK. HIS SITS WINTERS IN THE BARN AND ONLY HAS 50K ON IT. I WILL CHECK IT THIS WEEKEND. *JS
