WHILE DRIVING AT SLOW SPEEDS AND COMING TO A STOP MY ABS SYSTEM WILL ACTIVATE ON DRY PAVEMENT. THIS HAPPENS AT EVERY STOP I MAKE. THIS CAUSES INCREASE STOPPING DISTANCE AND CREATES A LARGE SAFETY RISK.

WHILE DRIVING MY TRUCK ON HIGHWAY 70, THE TRAFFIC SLOWED, I ATTEMPTED TO SLOW DOWN, BUT MY BRAKE PEDAL WENT TO THE FLOOR (RUSTED BRAKE LINES RUPTURED CAUSING TOTAL BRAKE FAILURE) AND I WAS UNABLE TO STOP. I WHIPPED THE STEERING WHEEL TO THE LEFT TO AVOID REAR ENDING UP COMING CARS. I MANAGED TO SLOW THE TRUCK DOWN BY PULLING DOWN TO 1ST AND WAS ABLE TO GET TO AN OFF RAMP, BUT WAS UNABLE TO STOP, BEFORE HITTING ANOTHER CAR AND A SIGN POLE. I HAVE OWNED MANY CARS THAT HAD FAR MORE MILES THAN MY TRUCK AND WERE NOT TAKEN CARE OF LIKE THIS TRUCK. NEVER HAVE I HAD A TOTAL BRAKE FAILURE ON ANY OTHER CAR. THIS SHOULD NOT EVER HAPPEN, NO MATTER WHERE YOU LIVE, SNOW REMOVAL METHODS, ETC. I WAS LUCKY, I COULD HAVE KILLED OR SERIOUSLY INJURED SOMEONE. I WOULD BET THERE HAS ALREADY BEEN MANY FATAL ACCIDENTS DUE TO THESE POOR BRAKE LINE BEING INSTALLED ON TRUCKS.

I WAS DRIVING TO ALABAMA FROM FLORIDA. WHEN I WAS ABOUT THREE HOURS OUT I WAS GOING DOWN THE ROAD HAULING A LOT OF PERSONAL ITEMS SINCE I WAS IN THE MIDDLE OF MOVING. IT STARTED STORMING REAL BAD SO I SLOWED DOWN TO 60 MPH AND AS I WAS APPROACHING ANOTHER VEHICLE THEY ALL THE SUDDEN SLAMMED ON THEIR BRAKES. I SAW THEM AS SOON AS THEY DID IT THEN I SLAMMED ON MY BRAKES AND THE PEDAL WENT STRAIGHT TO THE FLOOR. I ALMOST HIT THEM BUT I TURNED SHARP AND WENT INTO THE WOODS. I DIDN'T HIT ANYTHING BUT SMALL TREES SO VERY LITTLE DAMAGE TO OUTSIDE OF TRUCK. DAMAGE IS STILL THEIR BECAUSE SINCE THE WRECK I HAVE NOT BEEN ABLE TO WORK CAUSE I DESTROYED MY BACK AND NECK. AFTER THAT I STILL HAD TO DRIVE THE TRUCK THE REST OF THE THREE HOUR TRIP THAT ENDED UP TAKING NINE HOURS OF EXTREME PAIN AND SHOT NERVES. ONCE I FINALLY GOT HOME IT TOOK FOREVER AND A LOT OF MONEY TO HALF WAY FIX THE TRUCK. SINCE YOU CAN'T GET REPLACEMENT LINES AND HAD TO HAVE THEM CUSTOM MADE. TRUCK IS STILL CRAP BECAUSE NOW EVERY SINGLE PART OF THE BRAKE SYSTEM IS SHOT ALONG WITH THE BODY AND UNDERCARRIAGE. IT IS SOLID RUST NOW AND KEEPS BRAKING DOWN AND WILL COST AROUND THREE TO FIVE THOUSAND AT THE CHEAPEST TO FIX. IF I WOULD HAVE KNOWN WHAT I DO NOW THEN I WOULD HAVE SUED CHEVY AND THIS WORTHLESS ORGANIZATION CAUSE YALL HAVE KNOWN ABOUT THIS PROBLEM FOR A LONG TIME AND DID NOTHING. I THINK YALL AND CHEVY OWE ME AND THOUSANDS OF OTHER PEOPLE A LOT OF MONEY. IF YOU STILL DO NOTHING I WILL GO TO EVERY NEWS ORGANIZATION OR ANY OTHER COMPANY OR LAWYER THAT WILL GO AFTER YOUR COMPANY. YOU ARE HERE TO PROTECT PEOPLE FROM THINGS LIKE THIS BUT ALL YOU HAVE DONE IS HOPE WE ALL DIE. I WILL SPEND THE REST OF MY LIFE TRYING TO SHUT YOU DOWN AND MAKE EVERY PERSON THAT WORKS FOR THIS CRAP ORGANIZATION RESPONSIBLE FOR EVERY PERSON THAT GETS HURT OR DIES. JUST DO YOUR JOB THAT'S ALL I WANT.

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.
