I FIND IT PATICULARLY BAD WHEN TURNING. THIS HAS BEEN GOING ON FOR THE PAST THREE MONTHS, AND SEEM TO BE GETTING WORSE. I HAVE HAD THE BRAKES INSPECTED RECENTLY BY A MECHANIC AND NOTHING WRONG WAS FOUND WITH THE PADS OR ROTORS.

WHILE TRYING TO COME TO A STOP UPON ENTERING A PARKING SPOT IN FRONT OF A COUNTY HEALTH BLDG. THE BRAKE PEDAL ON MY TRUCK DID NOT RESPOND. THE PEDAL WENT HARD AND THE TRUCK CONTINUED FORWARD, I APPLIED THE BRAKE AGAIN WITH THE SAME RESULTS CAUSING THE TRUCK TO STRIKE THE BUILDING AND DESTROY A SERVICE ENTERANCE DOOR. I ESTIMATE MY SPEED TO HAVE BEEN UNDER 5 MPH SINCE THE AIRBAG DID NOT DEPLOY. I BELIEVE THIS IS THE RESULT OF A DEFFECTIVE ANTI-LOCK BRAKE SENSOR. AS OF TODAY I HAVE NOT BEEN TO THE DEALER TO HAVE THE FAILURE FIXED.

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.
