I HAVE OWNED THIS TRUCK FROM NEW. IT IS USED FOR LIMITED HAULING DUTIES AROUND TOWN AND HAS VERY LOW MILEAGE. LAST SUMMER I TOOK IT TO THE CHEVROLET DEALER FOR PA STATE INSPECTION. THE MECHANIC DROVE THE CAR INTO THE SERVICE BAY AND UPON DOING SO, THE BRAKE FLUID DUMPED OUT SUDDENLY FROM BENEATH THE TRUCK CHASSIS. THIS WAS 10 MIN AFTER I DROVE THE TRUCK TO THE DEALERS USING A LOCAL EXPRESSWAY. THE TRUCK WAS THEN PUT UP ON THE LIFT AND I WAS SHOWN THE FACT THAT THE BRAKE LINES WERE SEVERELY CORRODED TO THE POINT THAT THE BRAKE FLUID WAS DUMPED ONTO THE FLOOR. I PAID $2332 FOR BRAKE REPAIRS. AS A GRADUATE MATERIALS ENGINEER I INQUIRED AS TO THE MATERIAL USED FOR THE BRAKE LINES AND WAS TOLD THEY WERE CARBON STEEL. IT OFFENDS ME GREATLY THAT THIS TRUCK HAD THIS SEVERE FAILURE WITH LESS THAN 10K MILES, AND THAT GM APPARENTLY HAS BEEN AWARE OF THE PROBLEM AND HIDDEN IT FOR MANY YEARS. THEIR FOCUS ON SAVING A BUCK COULD HAVE COST LIVES AS A RESULT. THE DEALER WAS NOT HELPFUL IN MAKING ME AWARE OF ANY MITIGATION PROGRAM BY GM. AND I AM STUCK WITH A LARGE BILL FOR THEIR NEGLIGENCE. I AM APPALLED AND AN UNHAPPY CUSTOMER!!!

AS I APPROACHED A STOP SIGN AFTER TRAVELING ABOUT 30 MPH AND SLOWING DOWN FOR THE STOP SIGN I PRESS THE BRAKES AND IT WENT TO THE FLOOR AND PRESS THEM A SECOND TIME AND POSSIBLE A THIRD BEFORE CROSSING TRAFFIC AND FAILING TO STOP. I MISS HITTING A CAR BY INCHES. THIS WAS ALL ON AN UPHILL INCLINE. I CROSS TRAFFIC AND WAS ABLE TO STOP IN A CHURCH PARKING LOT BY USING THE PARKING BRAKE. AFTER ABOUT THE FIFTH TIME APPLYING THE BRAKES THE BRAKE WARNING LIGHT COME ON. NO WARNING UNTIL THEN. AFTER INSPECTION THE BRAKE LINE NEXT TO THE DRIVERS SIDE HAD RUPTURE. THE LINE LET A TRAIL OF BRAKE FLUID FOR ABOUT 200 YARDS. THE BRAKE FLUID WAS CHECKED AT OIL CHANGE SERVICE FOUR DAYS PRIOR AND WAS FULL. NOW IT IS EMPTY. THIS IS A MAJOR FAILURE THAT SHOULD BE CORRECTED BEFORE SOMEONE IS KILLED. I THOUGH THAT THERE WAS A SECONDARY SYSTEM TO STOP IF ONE HALF OF THE SYSTEM FAILED. APPARENTLY NOT!!!!! *TR

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.
