WHILE TRAVELING AT 25MPH AND COMING TO A SLIGHT ABRUPT STOP, THE BRAKE PEDAL FELL TO THE FLOOR WHILE DEPRESSING THE PEDAL TO STOP. THE VEHICLE CAME SLOWLY TO A STOP WITH STEAM RISING FROM UNDER THE VEHICLE. UPON PULLING THE VEHICLE TO A SAFE LOCATION AND UPON INSPECTION, IT APPEARS AS IF ONE OF THE METALLIC (ASSUMING STEEL) BRAKE LINES FEEDING FROM THE MASTER CYLINDER TO THE ABS BLOCK HAD BURST. NO INDICATION LIGHTS ON THE DASH OF A BRAKING SYSTEM FAILURE OR LOW PRESSURE ALERT FOR THE SYSTEM. IT APPEARS THAT THE BRAKE LINES WERE CORRODED/RUSTED. UPON DISCUSSING WITH A REPUTABLE AUTO SHOP, THEY INDICATED THAT THIS IS A COMMON ISSUE ON THIS MODEL YEAR VEHICLE AND THAT A REPAIR TO REPLACE THE LINES MAY BE REQUIRED. THIS IS A SAFETY ISSUE IN MY OPINION AND IF THE MATERIALS USED TO MAKE THIS SAFETY SYSTEM WERE NON-CORROSIVE; THIS WOULD HAVE NOT HAPPENED. *TR

LEAVING FROM WORK AT THE GREATER CINCINNATI AIRPORT. DRIVING DOWN THE RAMP TO THE STOP SIGN AT DONALDSON RD. WHILE ATTEMPTING TO BRAKE FOR THE STOP SIGN THE BRAKE PEDAL WENT TO THE FLOOR CAUSING THE TRUCK TO GO THROUGH THE STOP SIGN ACROSS THE EAST BOUND LANES OF DONALDSON ROAD AND FINALLY STOP BEFORE ENTERING A DITCH ON THE NORTH SIDE OF THE ROAD. AT FIRST, I WAS GOING TO HAVE THE CAR TOWED. I FOUND THAT THERE WAS SOME RESIDUAL BRAKING LEFT AND I, SLOWLY, DROVE THE CAR APPROXIMATELY 12 MILES TO MY HOUSE. THE NEXT DAY I TOOK THE CAR TO THE LOCAL SHOP AND UPON INSPECTION WAS TOLD THAT ONE OF THE BRAKE LINES HAD FAILED DUE TO CORROSION. I WAS ALSO TOLD THAT "ALL" BRAKE LINES NEEDED TO BE REPLACED DUE TO CORROSION. TOTAL BILL WAS OVER 1200 DOLLARS. 2002 CHEVROLET SILVERADO EXTENDED CAR/LONG BED 1500. *TR

2002 CHEVY SILVERADO TRUCK WAS SITTING IN DRIVEWAY I WAS READY TO LEAVE PUSHED ON THE BRAKE TO PUT IT IN DRIVE AND THE PEDAL WENT TO THE FLOOR . LOOKED UNDER THE VEHICLE FLUID EVERWHERE. NOT ONE LEAK OR ANY SIGN BEFORE. I KNEW WHAT IT WAS BECAUSE I KNOW AT LEAST 4 OTHER PEOPLE WITH CHEVY TRUCKS AND THIER LINES WENT, 1 HAD AN ACCIDENT RUNNING IN TO THE REAR OF A CAR. I HAVE A NEW LINE SET BUT DIDN'T GET TO IN TIME. IF THAY HADN'T FAILED IN MY DRIVEWAY THE OUTCOME WOULD HAVE BEEN INTIERLY DIDERENT WITH MY SON HIS FRIEND AND MYSELF. ONE WOULD THINK THEY WOULD USE A MATERIAL TO WITHSTAND THE ELEMENTS ON BRAKES!!!!! MY WORK TRUCK TRUCK IS A 2001 SILVERADO SO I CHECKED IT AND THERE GONE ALSO. I WOULD BE WILLING TO BET THAT MOST PEPOLE FIX THE LINES AND DON'T REPORT. TO ME THIS IS A BIG PROBLEM. *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.
