I HAVE A 1999 CHEVROLET SILVERADO AND MY ABS LIGHT AND PARKING BRAKE LIGHT HAS CAME ON RECENTLY. THE BRAKING ON MY TRUCK IS NOT VERY GOOD IN WET CONDITIONS. I FOUND THAT IT IS A COMMON PROBLEM ON CHEVY TRUCKS, AND I WAS TOLD THAT I SHOULD JUST REMOVE THE FUSE. I WAS TOLD IT HAS SOMETHING TO DO WITH THE WHEEL HUB ASSEMBLY, AND IT IS A COSTLY FIX. I THINK FOR ONCE CHEVROLET SHOULD STEP UP AND PUT OUT A RECALL ON THIS PROBLEM. THERE IS ALSO ANOTHER COMMON COMPLAINT ABOUT MY DASH CLUSTER, WHICH I HAD ALSO FOUND IS A COMMON PROBLEM, THE ODOMETER WILL GO OFF AND ON WHEN IT FEELS LIKE, AND THE GAS GAUGE FREQUENTLY GOES UP AND DOWN, AND THE FUEL LIGHT COMES ON PERIODICALLY. THANK YOU FOR YOUR TIME. *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.
