I HAVE A 2002 SILVERADO 2500HD WITH VERY LOW MILES(63,868), EXTREMELY WELL TAKEN CARE OF VEHICLE. MY PROBLEM OCCURRED, FORTUNATELY FOR ME, WHILE I WAS SITTING AT A STOPLIGHT. AS I SAT WAITING FOR THE LIGHT TO TURN GREEN, MY BRAKE PEDAL WENT TO THE FLOOR. I WASN'T SURE WHAT HAPPENED AND THOUGHT MAYBE I'D PUMP MY BRAKES UP AND EVERYTHING WOULD BE FINE. NO SUCH LUCK. I PULLED OVER INTO A GAS STATION AND LOOKED UNDER MY TRUCK AND SAW MY FLUID LEAKING VERY BADLY, COMING DOWN OVER MY GAS TANK. SINCE I HAD JUST LEFT MY HOME AND WAS VERY CLOSE, I DECIDED TO DRIVE IT HOME AND HAVE A BETTER LOOK. AS I DROVE THE HALF MILE DRIVE, MY BRAKE FLUID COMPLETELY DRAINED DRY. FORTUNATELY FOR ME, THERE WAS NO TRAFFIC ON THE STREETS AND NO OBSTACLES IN THE WAY. ANYWAY, WHEN I GOT HOME AND LOOKED UNDER MY TRUCK AND SAW THAT MY BRAKELINE LOOKED LIKE IT COMPLETELY EXPLODED AND WAS RUSTED OUT, I CALLED MY DEALER AND ASKED IF THERE WAS A SAFETY RECALL FOR THESE BRAKE LINES, AND THEY INFORMED ME THAT THERE NEVER HAS BEEN. I MADE AN APPOINTMENT FOR THEM TO REPAIR MY BRAKELINE, SO I HAD MY TRUCK TOWED TO MY DEALER, AND THEY PRECEDED TO WORK ON MY TRUCK. AS THEY INSPECTED IT, I WAS INFORMED THAT "ALL" OF MY LINES WERE RUSTED OUT BADLY AND UNSAFE. THIS COST ME APPROXIMATELY $700 TO REPAIR ALL OF THE LINES, BUT MY BIGGEST CONCERN IS THAT THIS COULD HAVE TURNED OUT A LOT DIFFERENTLY. WE HAVE 8 CHILDREN, 12 GRAND CHILDREN, AND FORTUNATELY THIS VEHICLE WAS NOT ON THE HIGHWAY WITH ANY OF THE LITTLE ONES IN IT. I HAVE BEEN DRIVING FOR OVER 30 YEARS AND I FEEL VERY FORTUNATE THAT CIRCUMSTANCES WERE WHAT THEY WERE. ANYWAY, AFTER SURFING THE WEB, I FOUND THAT I AM NOT ALONE, THIS IN MY OPINION IS A SAFETY HAZARD AND SOMETHING SHOULD BE DONE BEFORE A TRAGEDY HAPPENS. *TR

BRAKE FAILURE RESULTING IN ACCIDENT DUE TO RUSTED STEEL LINE AND LOOSE (STRETCHED) PARKING BRAKE CABLE. RESIDENTIAL DRIVING UNDER 25 MILES AN HOUR I APPROACHED A STOP LIGHT WITH MY FAMILY IN THE CAR. APPLIED PRESSURE TO BRAKE WITH ABOUT 100 FEET FROM LIGHT. BRAKE PEDAL DROPPED TO THE FLOOR. IMMEDIATELY I APPLIED PARKING BRAKE. VEHICLE FAILED TO RESPOND TO BOTH ACTIONS. THE TRUCK ROLLED THROUGH THE STOP LIGHT CAUSING AN ACCIDENT. MAIN LINE FEEDING REAR BRAKES ABRUPTLY FAILED CAUSING PERSONAL AND PROPERTY DAMAGES. AFTER HAVING THE BRAKES SERVICED AND FIXED, AND THINKING THAT THE TRUCK WAS SAFE, THE POWER STEERING PUMP FAILED WHILE DRIVING ON THE HIGHWAY AT APPROXIMATELY 65 MPH. BOTH STEERING AND BRAKING WERE NON RESPONSIVE. HAD I HAVE BEEN DRIVING ON A RESIDENTIAL ROAD THIS COULD HAVE CAUSED A SERIOUS ACCIDENT. HOWEVER, THE HIGHWAY GAVE ME AMPLE TIME TO SLOW DOWN AND GET MY FAMILY TO THE SHOULDER OF THE ROAD. THE TRUCK WAS TOWED AND DIAGNOSED. A NEW POWER STEERING PUMP WAS PUT IN. I AM SCARED TO DRIVE THE TRUCK WITH MY FAMILY IN IT. I DO NOT KNOW WHAT IS GOING TO BRAKE NEXT. *TR

I JUST PURCHASED MY TRUCK IN JUNE FROM A PREVIOUS OWNER IN SOUTH FLORIDA. AS FAR AS I KNOW, THE TRUCK HAS BEEN IN FLORIDA SINCE IT WAS PURCHASED NEW. ON FRIDAY, NOVEMBER 8, 2013, I WAS FORCED TO BRAKE HEAVILY AT AN INTERSECTION. I FELT THE ANTI-LOCK BRAKES ACTIVATE AND THE TRUCK STOPPED. I PROCEEDED TO THE NEXT INTERSECTION AND WAS TRAVELING APPROXIMATELY 50MPH. WHEN I STEPPED ON THE BRAKE PEDAL, THE PEDAL WENT TO THE FLOOR. I IMMEDIATELY DOWN SHIFTED IN AN ATTEMPT TO SLOW DOWN. LUCKILY, THERE WERE NO VEHICLES IN THE RIGHT TURN LANE SO I MADE A VERY DANGEROUS RIGHT TURN NEARLY STRIKING VEHICLES IN ANOTHER LANE. I ATTEMPTED TO BRAKE AGAIN AND ONLY THE PASSENGER SIDE REAR TIRE WOULD LOCK UP. I WAS ABLE TO STOP THE TRUCK WITH THE EMERGENCY BRAKE AND DISTANCE. I THOUGHT THE MASTER CYLINDER WENT OUT BUT UPON FURTHER INSPECTION. A BRAKE LINE HAS SPLIT AND IS EXPELLING BRAKE FLUID. THE LOCATION OF THE HOLE IS WHERE THE BRAKE LINE PASSES DIRECTLY BELOW THE DRIVER'S DOOR BEFORE THE CONNECTION TO THE ANTI LOCK BRAKE SYSTEM. HOW IS THIS NOT A RECALL. I COULD HAVE KILLED MYSELF OR SOMEONE ELSE. I HAVE NEVER SEEN A BRAKE SYSTEM FAILED WHERE THERE IS NO BRAKES AT ALL. *TR

AFTER DROPPING OFF A BOAT FOR WINTER STORAGE, I WAS LEAVING THE STORAGE LOCATION AND ATTEMPTED TO APPLY BRAKES AND THE PEDAL DROPPED TO THE FLOOR. I HAD TO TAKE A VERY SLOW ROUTE HOME AS THE BRAKE PEDAL CONTINUED TO DROP TO THE FLOOR ANYTIME THE BRAKES WERE APPLIED. IN A COUPLE OF INSTANCES WHEN THE BRAKE PEDAL WAS PRESSED HARD, THE ABS SYSTEM DID ACTIVATE. FINALLY HAD A CHANCE TO PULL THIS VEHICLE INTO MY GARAGE FOR EXAMINATION ON 11/8/13 AND FOUND THE BRAKE LINES UNDER THE DRIVERS' FLOORBOARD AT THE FRAME-RAIL EXTREMELY CORRODED TO THE POINT OF FAILURE OF ONE OF THE FIVE LINES. THE OTHERS ARE MOST CERTAINLY NOT FAR BEHIND. THIS VEHICLE IS MAINLY USED IN THE WINTER MONTHS. I AM GRATEFUL THAT THE PROBLEM SURFACED NOW BEFORE THE SNOWMOBILE SEASON WHEN I AM HAULING A 24 FOOT TRAILER WITH FOUR PASSENGERS AND FOUR SNOWMOBILES ON ROADS THAT ARE NOT IN THE BEST SHAPE TO BEGIN WITH. THIS COULD HAVE BEEN A VERY BAD SITUATION TO SAY THE LEAST! GM NEEDS TO FIX THIS ISSUE BEFORE SOMEONE IS SERIOUSLY INJURED OR WORSE - THESE OBVIOUSLY ARE NOT ISOLATED INCIDENTS. *** PLEASE NOTE THAT THERE HAS YET TO BE A SINGLE WARNING LAMP TO COME ON AFTER APPLYING THE BRAKES AT LEAST TWENTY FIVE TIMES - NO MIL, NO BRAKE, NOTHING! *** I WILL BE TAKING A COMPLETE SERIES OF PICTURES OF THE CONDITION OF THESE LINES BEFORE THE REPAIRS ARE PERFORMED IF THEY ARE NEEDED FOR THIS COMPLAINT. *TR
