WHILE DRIVING HOME, SOMEONE PULLED OUT IN FRONT OF ME. I APPLIED THE BRAKES AND THE PEDAL WENT STRAIGHT TO THE FLOOR. I MANAGED TO AVOID A COLLISION AND MADE IT HOME AS THIS HAPPENED LUCKILY AROUND THE CORNER FROM MY HOUSE. I LOOKED FOR THE PROBLEM, IT DIDN'T TAKE LONG AS UNDER THE HOOD THE FRAME WAS COVERED WITH BRAKE FLUID. I WAS AMAZED TO FIND THAT ONE OF THE METAL BRAKE LINE HAD RUSTED THROUGH AND THE OTHERS DON'T LOOK TO BE IN VERY GOOD CONDITION. NEEDLESS TO SAY I WILL BE REPLACING ALL THE BRAKE LINES WITH STAINLESS STEEL LINES (A COST OF $350.00). I CAN'T IMAGINE WHY STAINLESS STEEL LINES ARE NOT ORIGINAL EQUIPMENT. RUST SEEMS TO BE A PROBLEM WITH THIS VEHICLE NOT ONLY THE BRAKE LINES BUT ALSO PARTS OF THE SUSPENSION.

THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 5 MPH WITH THE VEHICLE IN REVERSE AND DEPRESSING THE BRAKES, THE BRAKES WENT STRAIGHT TO THE FLOOR BOARD. THE CONTACT ENGAGED THE EMERGENCY BRAKE TO STOP THE VEHICLE. THE CONTACT STATED THAT THE ABS WARNING LIGHTS ILLUMINATED ON THE INSTRUMENTAL PANEL. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY ADVISED HIM THAT THE BRAKE LINES IN THE REAR OF THE VEHICLE WERE RUSTED AWAY AND THEY NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED FOR THE REAR BRAKE LINES. APPROXIMATELY 4 MONTHS LATER THE CONTACT STATED THAT THE FAILURE RECURRED WHILE DRIVING SLOWLY IN A PARKING LOT. THE CONTACT STATED THAT THE MECHANIC WAS ON SITE AND ADVISED HIM THAT THE BRAKE FLUID WAS POURING OUT RAPIDLY. THE VEHICLE WAS TAKEN TO THE DEALER AGAIN AND THEY INFORMED HIM THAT BRAKE LINES ALONG THE DOOR WERE RUSTED. THE VEHICLE WAS REPAIRED FOR THE BRAKE LINES. THE MANUFACTURER WAS CONTACTED AND THEY OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 177,000 AND THE CURRENT MILEAGE WAS APPROXIMATELY 178,000.

REAR BRAKE LINE DEVELOPED LEAK MAKING VEHICLE HARD TO CONTROL, VERY CLOSE TO HAVING ACCIDENT. I GUEST GM WOULD RATHER PAY OUT FOR A FEW ACCIDENT DEATHS THAN REPAIR THIS DEFECT. IT SEEMS ITS ALL ABOUT THE DOLLAR THAN SAFETY. *TR

WHEN OPERATING VEHICLE AT SLOW SPEED AND ATTEMPTING TO STOP ANTI LOCK BRAKES ENGAGE AND INCREASED STOPPING DISTANCE IS REQUIRED. THIS VEHICLE WAS RECALLED FOR SAME PROBLEM IN 2005. I MADE AN ATTEMPT AT MY LOCAL GMC DEALER TO REMEDY THIS CONTINUING PROBLEM. HOWEVER, I WAS INFORMED THAT GENERAL MOTORS WOULD ONLY MAKE ONE ATTEMPT TO REMEDY ISSUE AND THAT I ALREADY HAD USED THAT. THE DEALER REPRESENTATIVE STATED THAT I COULD PULL THE FUSE ON THE ABS AND THE VEHICLE WOULD PERFORM STOPPING WITHOUT THE AID OF ABS AND WOULD STOP NORMALLY IN DRY ENVIRONMENT, WITHOUT THE ASSISTANCE OF ANTI LOCK BRAKES. I FEEL THIS IS A DESIGN PROBLEM AND IS A TREMENDOUS SAFETY ISSUE. I DID TAKE VEHICLE TO ANOTHER MECHANIC WHO DROVE VEHICLE IN HIS PARKING LOT AND THE PROBLEM OCCURRED TO HIM ALMOST CAUSING A CRASH IN HIS LOT. *JB

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.
