TRUCK HAD FAILED TO STOP AT AN INTERSECTION AS WE APPROACHED RED LIGHT. UPON DEPRESSING THE PEDAL THE BRAKE PEDAL WENT TO THE FLOOR JUST ENOUGH TO GET TRUCK SLOWED BEFORE EMERGENCY PEDAL WAS DEPRESSED TO COME TO A COMPLETE STOP. WE WERE TRAVELING ABOUT 20 MILES AN HOUR BEFORE WE REACHED INTERSECTION ABOUT 75 YARDS AWAY. AS LIGHT TURNED GREEN, WE SLOWLY PULLED INTO A PARKING LOT AND PARKED TRUCK UNTIL A TOW TRUCK COULD GET VEHICLE BACK TO THE GARAGE FOR REPAIRS. UPON INSPECTION BY OUR MECHANIC, IT WAS FOUND THAT THE BRAKE LINE HAD RUPTURED NEAR THE ANTI-LOCK BRAKE HOUSING WHICH WAS CAUSED BY CORROSSION AND POOR BRAKE LINE TUBING MATERIAL. IT WAS NOTED THAT MATERIAL WAS NOT STAINLESS STEEL OR ANY NON-CORROSIVE MATERIAL SUPPLIED AND INSTALLED BY THE OEM. IT TOOK TWO WEEKS FOR OUR TRUCK TO BE REPAIRED AS THE MECHANIC HAD TO CUSTOMER BEND THE NEW BRAKE LINES BECAUSE OEM DOES NOT HAVE REPLACEMENT LINES WHICH CAME TO A FINAL COST OF CLOSE TO $1300. *TT

1ST INCIDENT ON OR ABOUT NOVEMBER 2010 REAR BRAKE LINE FAILURE NO PREVIOUS WARNING LIGHT INDICATION - STEEL LINE BURST CAUSING BRAKE FAILURE ALONG WITH EMERGENCY BRAKE FAILED THIS HAPPENED AT ABOUT 10 MILES AN HOUR SO THE VEHICLE WAS ABLE TO BE STOPPED BY A CURB. TESTING THE BRAKES NONE WORKED EVEN THOUGH IT WAS A REAR LINE FAILURE. VEHICLE TOWED AND REPAIRED BY REPLACING THE LINE FROM ABSBOX TO REAR AND THE EMERGENCY BRAKE SHOES AND REAR DISC PADS WERE ALSO REPLACED. EVEN WITH THE EMERGENCY BRAKE SHOE REPLACEMENT ITS ABILITY TO STOP THE TRUCK WAS MINIMAL AT BEST 2ND INCIDENT ON OR ABOUT AUGUST 2011 THE TRUCK FAILED TO PASS NC STATE SAFETY INSPECTION AS EMERGENCY BRAKE WOULD NOT HOLD - THE EMERGENCY BRAKE SHOES AND REAR DISC PADS WERE REPLACED AGAIN WITH SIMILAR RESULTS WITH THE PREVIOUS REPLACEMENT - WITH MARGINAL EMERGENCY BRAKING OPERATION, BUT ENOUGH TO PASS THE NC STATE INSPECTION - ALSO THE BACKING PLATES OF THE REAR BRAKES HAD TO BE REPLACED AS THEY HAD RUSTED AWAY 3RD INCIDENT ON OR ABOUT OCTOBER 2011 FRONT BRAKE FAILURE NO PREVIOUS WARNING LIGHT INDICATION - STEEL LINE TO FRONT BRAKES BURST WHERE TWO OF THE LINES WERE RUBBING TOGETHER WHERE THEY CROSS OVER THE FRAME FROM THE ABS BOX. THIS OCCURRED AT A STOP SIGN. THE HYDRAULIC SYSTEM MAINTAINED SOME STOPPING ABILITY AND THAT COMBINED WITH THE RECENTLY REPLACED EMERGENCY BRAKE PADS DID STOP THE TRUCK JUST SLIGHTLY PAST THE STOP SIGN. TO MOVE THE VEHICLE TO A SAFE LOCATION IT HAD NO HYDRAULIC STOPPING ABILITY, BUT THE EMERGENCY BRAKE DID FUNCTION MARGINALLY AT THE VERY SLOW SPEED. THE VEHICLE AGAIN NEEDED TO BE TOWED. DUE TO THE WAY THE FRONT FOUR STEEL LINES ARE RUN AND BUNDLED TOGETHER WITH OBVIOUS OTHER POINTS WHERE THESE LINES RUB TOGETHER COMBINED WITH RUST WILL REQUIRE ALL THE FRONT STEEL LINES TO BE REPLACED INCLUDING THE STEEL LINES FROM THE MASTER CYLINDER TOO THE ABS BOX. *TT

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.
