I STARTED TO HYDROPLANE WHEN I HIT THE GRAVEL, ROCK PART OF THE ROAD AND SKIDDED INTO THE RIGHT SIDE OF THE BRIDGE HITTING MY PASSENGER TIRE AND BOUNCING ME OUT AND SPINNING AROUND. I TRIED TO COMPENSATE BY APPLYING BRAKES GENTLY AND MY BRAKES LOCKED UP, MY SEAT BELT DID NOT HOLD ME BACK AS I HIT THE STEERING WHEEL WITH MY HEAD AND CHEST. I THEN WAS SPUN HEAD ON INTO THE LEFT SIDE OF THE BRIDGE AND SMASHED THE ENTIRE FRONT END OF MY TRUCK. I WAS SO SCARED AND ALL I COULD THINK IS WHEN IS MY AIRBAG GOING TO GO OFF, IT NEVER DID. THERE IS OVER $5000.00 DAMAGE TO MY VEHICLE AND IT IS ONLY WORTH $8000.00. I WENT TO THE ER AND SUFFERED MILD CONCUSSION, NECK STRAIN AND BRUISED CHEST. *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.
