LUCKILY THERE WERE NO OTHER CARS COMING IN THE OPPOSITE DIRECTION OR I WOULD HAVE BEEN HIT.

FOR GM TO SAY THAT 1 LINE WOULDN'T CAUSE A COMPLETE LOSS OF BRAKING POWER IS WRONG. I HAD A COMPLETE LOSS OF BRAKING POWER WITH ONLY 1 LINE COMPLETELY RUSTED THROUGH.

WAYNE, IN AREA WHERE THEY USE SALT THROUGHOUT THE WINTER MONTHS. I BOUGHT THE TRUCK FROM MY WIFE'S SISTER. I KNOW THE TRUCK WAS GARAGED AND WELL MAINTAINED.

THE BRAKE LINES ON MY TRUCK HAVE FAILED ON THREE SEPARATE OCCASIONS. THE FIRST TIME WAS IN MY DRIVEWAY WHEN I HAD JUST STARTED TO BACK UP. THE SECOND TIME WAS ALSO IN MY DRIVEWAY RIGHT BEFORE I WAS ABOUT TO PULL INTO TRAFFIC. THE MOST RECENT FAILURE WAS AS I WAS APPROACHING A RED LIGHT IN A 35 MPH ZONE. ON THAT LAST OCCASION, I IMMEDIATELY SHIFTED TO THE LOWEST GEAR AND TURNED RIGHT INTO THE PARKING LOT I HAPPENED TO BE NEAR. I WAS ABLE TO BRING THE TRUCK TO A REST IN A SNOW BANK AND AWAIT A TOW TRUCK. THE MECHANICS THAT REPLACED THE LINES EACH TIME STATED THAT I SHOULDN'T HAVE A FAILURE AGAIN BECAUSE THIS WAS THE THIRD AND FINAL LINE THAT WAS CORRODED. *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.
