TWO OF THE BRAKE LINES SPLIT OPEN WHILE APPLYING THE BRAKES DURING A ROUTINE DECELERATION TO STOP AT AN INTERSECTION. BRAKE PEDAL WENT TO THE FLOOR AND VEHICLE FAILED TO SLOW. I HAD TO APPLY THE PARKING BRAKE TO BRING THE VEHICLE SAFELY TO A STOP IN AN ADJOINING PARKING LOT. UPON INSPECTION THE BROKEN LINES AND LEAKING BRAKE FLUID WE SEEN. THE BRAKE RESERVOIR LOST NEARLY 10OZ. OF FLUID. THE BRAKE LINES ARE WELL KNOWN IN THE AUTO REPAIR TRADE CIRCLES TO BE MADE OF INFERIOR STEEL AND GM SHOULD OFFER REPLACEMENT AT NO CHARGE. FOR JUXTAPOSITION, I OWN A 1995 JEEP WRANGLER WITH THE SAME AMOUNT OF MILES AND HAS STAINLESS STEEL BRAKE LINES AND THE LOOK WEATHERED, BUT NO CORROSION AND NEVER A FAILURE. *TR

TL* THE CONTACT OWNS A 2000 SILVERADO 1500. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 45 MPH, THE BRAKE PEDAL WENT TO THE FLOOR ABRUPTLY WHEN ENGAGED. THE BRAKES WERE APPLIED REPEATEDLY HOWEVER, THE VEHICLE FAILED TO SLOW DOWN. THE VEHICLE WAS MANEUVERED OFF THE ROAD IN A BACK AND FORTH MOTION ONTO A GRASSY SURFACE UNTIL REACHING A PARKING LOT. THE VEHICLE CAME TO A STOP AFTER DRIVING OVER A SPEED BUMP. THE CONTACT INSPECTED THE VEHICLE AND PLACED A RUBBER HOSE OVER THE HOLES IN THE FAULTY BRAKE LINES AND SECURED WITH SUPPORT CLAMPS. THE VEHICLE WAS DRIVEN TO THE RESIDENCE AT AN EXTREMELY LOW SPEED. THE CONTACT REPLACED BOTH FRONT BRAKE LINES AND MAIN LINES HIMSELF. THE MANUFACTURER WAS NOTIFIED OF THE ISSUE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 105,000.

ON 09/21/2014 AT APPROXIMATELY 1100 HOURS I HAD JUST COME OFF INTERSTATE 66 WEST.I WAS ENTERING A GATED COMMUNITY IN GAINESVILLE, VA. I STOPPED AT THE GUARD BOOTH TO SHOW I.D. I NOTICED SOME SMOKE AT THE GUARD BOOTH AND THOUGHT IT WAS THE CAR BEHIND ME. I SLOWLY ACCELERATED TO THE NEXT CROSS STREET. I ATTEMPTED TO BRAKE TO MAKE A LEFT TURN AND THE BRAKE PEDAL WENT TO THE FLOOR. I ATTEMPTED TO PUMP THE BRAKES AND I STILL HAD NO BRAKING. I HAD TO UTILIZE MY EMERGENCY BRAKE TO STOP. THE SMOKE WAS FROM MY VEHICLE. IT WAS FROM THE BRAKE FLUID POURING OUT THE RUSTED BRAKE LINES ONTO THE EXHAUST. THE REASON I HAD COMPLETE BRAKE FAILURE WAS DUE TO BOTH LINES FROM THE MASTER CYLINDER FAILING AT THE SAME TIME. THE LOCATION OF THE LINE FAILURE WAS ON THE FRAME RAIL CLOSER TO THE MASTER CYLINDER (NOT FURTHER DOWN BY THE DRIVER'S DOOR). I AM THANKFUL THAT THE BRAKE FAILURE DID NOT OCCUR AT HIGH SPEED AND OR IN HEAVY TRAFFIC. I AM THANKFUL THAT THERE WERE NO PEDESTRIANS PRESENT THAT I HAD TO BRAKE FOR AND NO PROPERTY DAMAGE. I PERSONALLY INSPECTED THE BRAKE LINES AFTER THE INCIDENT AND HAVE FOUND THE CORROSION EXCESSIVE. I HAVE ORDERED A KIT TO REPLACE ALL THE BRAKE LINES BECAUSE THIS IS A SERIOUS SAFETY ISSUE. THIS IS THE FIRST TIME I HAVE EVER REPORTED ANY DEFECT ON ANY VEHICLE. I AM REPORTING THIS BECAUSE I BELIEVE IT IS THAT SERIOUS OF A SAFETY CONCERN. THIS IS NOT NORMAL WEAR AND THE BRAKE LINE MATERIAL AND DESIGN ARE AT FAULT. *TR

AS I WAS ABOUT TO PUT MY VEHICLE IN REVERSE, AND BACK OUT OF MY DRIVEWAY, I PRESSED DOWN ON THE BRAKE PEDAL, AND IT WENT RIGHT TO THE FLOOR. I TRIED PRESSING IT AGAIN, AND IT WENT TO THE FLOOR AGAIN. UPON INSPECTION UNDER THE VEHICLE, I DISCOVERED THAT ONE OF THE BRAKE LINES HAD RUSTED THROUGH AND BURST. THANK GOD THAT I WAS NOT ACTUALLY IN MOTION WHEN THIS HAPPENED, AS I NEED TO BACK INTO A VERY BUSY STREET (ACTUALLY, IT'S A HIGHWAY) AND THERE IS NO TELLING WHAT COULD HAVE HAPPENED. THIS IS NOT AN ISOLATED INCIDENT, AS I HAVE COME ACROSS NUMEROUS COMPLAINTS ON THE INTERNET, AND ACTUALLY I'VE HAD TO REPLACE A DIFFERENT BRAKE LINE THAT WAS RUSTED THROUGH SEVERAL MONTHS AGO. APPARENTLY, CHEVROLET DOES NOT THINK THIS IS SOMETHING THAT NEEDS TO BE TAKEN CARE OF. THEY ARE WRONG! *TR

WHILE DRIVING ON A 4 LANE HIGHWAY A VEHICLE DRIVING FROM THE OPPOSITE DIRECTION MAKE A SUDDEN LEFT TURN CAUSING ME TO QUICKLY APPLY THE BRAKES TO AVOID A COLLISION. THIS CAUSED THE BRAKE LINE TO FAIL LEAVING ME WITH VERY LITTLE BRAKE FOR THE DRIVE HOME. THIS IS THE SECOND TIME. TWO YEARS AGE THREE BRAKE LINES FAILED. *JS

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
