LOSS OF BRAKING EFFECTIVENESS AT LOW SPEED WHEN TURNING WHEEL. WHILE MAKING LEFT HAND TURN INTO DRIVEWAY AT LOW SPEED ON DRY PAVEMENT, ANTI-LOCK BRAKING SYSTEM ACTIVATED CAUSING LOSS OF BRAKING. BRAKE PEDAL "FROZE" AT POSITION AND WOULD NOT ALLOW PEDAL TO BE DEPRESSED FURTHER. VEHICLE CONTINUED FORWARD UNTIL IMPACTING THE EXTERIOR GARAGE WALL CAUSING STRUCTURAL DAMAGE TO THE HOME. UPON FURTHER TESTING VEHICLE IN OPEN, DRY PARKING LOT, THE ANTILOCK SYSTEM ACTIVATES INCORRECTLY WHEN TURNING WHEEL LEFT OR RIGHT WHILE BRAKING AT LOW SPEED. THIS VEHICLE HAD WHEEL SENSOR SERVICE FOR RECALL CAMPAIGN 05068C PERFORMED ON FEBRUARY 20, 2012. THE GM WHEEL SPEED SENSOR RECALL CAMPAIGN APPARENTLY IS NOT A PERMANENT FIX FOR THE ROOT CAUSE OF FAILURE, BUT ONLY A TEMPORARY BAND-AID SOLUTION. FORTUNATELY THERE WAS NO ONE IN VICINITY OF FRONT OF VEHICLE WHEN THIS INCIDENT OCCURRED, OTHERWISE SERIOUS PHYSICAL INJURY OF LOSS OF LIFE COULD HAVE OCCURRED. *TR

ON MY WAY TO THE STORE I NOTICED REDUCED BRAKE PEDAL AND INCREASED STOPPING DISTANCE. NO WARNING LIGHTS WERE ON AT THIS TIME. ON MY WAY HOME THE BRAKE WARNING LIGHT CAME ON AND I HAD EVEN LESS PEDAL AND NEEDED EXTREME STOPPING DISTANCE. I WENT DIRECTLY TO THE REPAIR STATION AND THE MECHANIC FOUND HEAVILY RUSTED LINES ESPECIALLY IN THE AREAS OF THE ABS MODULE. ONE OF THE LINES WAS RUSTED THRU AND LEAKING IN THE AREA OF THE ABS MODULE CAUSING THE MALFUNCTION. I ALREADY HAVE HAD THE BRAKE LINES TO THE FRONT CALIPERS REPLACED IN JULY OF 2012 DUE TO EXTREME RUST. I AM HAVING ALL THE BRAKE LINES REPLACED WITH STAINLESS STEEL AT THE TIME OF THIS POSTING. THIS VEHICLE GETS VERY LIGHT DUTY PERSONNEL USE AND SHOWS NO SIGNS OF RUST IN THE BODY. *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.
