DRIVING VEHICLE AT APPROX 45MPH, CAME TO STOP AT RED LIGHT AND BRAKE PEDAL WENT COMPLETELY TO THE FLOOR. PUMPED THE BRAKE PEDAL AGAIN AND NOTHING. DOWN SHIFTED TRANSMISSION TO SLOW DOWN AND PRESSED THE EMERGENCY BRAKE TO COME TO A STOP. PULLED OVER TO THE SIDE OF THE ROAD, LIFTED THE HOOD NO BRAKE FLUID IN REAR SECTION OF MASTER CYLINDER. NOTICED BRAKE FLUID DRIPPING UNDER THE FRONT OF THE DRIVERS DOOR ON THE GROUND. HAD THE VEHICLE TOWED HOME AND LOOKED UNDER THE VEHICLE AND THE BRAKE LINE WAS DRIPPING FLUID. THE BRAKE LINES ARE COMPLETELY RUSTED AND THE FRAME IS REALLY RUSTED. JUST GOT THE VEHICLE OUT OF THE GMC SHOP FOR ROUTINE SERVICE. CAN'T FIGURE WHY THEY DIDN'T NOTICE OR AT LEAST TELL ME THAT I MIGHT HAVE A PROBLEM.I CALLED THEM AND ADVISE WHAT ISSUE I WAS HAVING. THEY ADVISED THAT GM WOULD NOT COVE THE ISSUE AND 1300.00 WOULD MAYBE COVER THE LINE REPLACEMENT PLUS. I AM NOT HAPPY. WORKED HARD TO BUY THIS VEHICLE AND NOW THAT I AM RETIRED FROM THE MILITARY I REALLY DO NOT HAVE THE FUNDS TO REPLACE THE LINES AND DO SOMETHING ABOUT THE RUSTY FRAME. *TR
