WHILE DRIVING IN DOWNTOWN CITY AREA, VEHICLE IN MOTION, ATTEMPTED TO APPLY BRAKES AND PEDAL WENT STRAIGHT TO FLOOR ALMOST CAUSING AN ACCIDENT. THERE WAS NO WARNING TO LOSS OF BRAKING SYSTEM. VEHICLE WAS BROUGHT TO RESIDENCE AND REVIEWED. BRAKE LINES FROM MASTER CYLINDER HAVE SUFFERED RUST DAMAGE AND CAUSED A FAILURE OF THE BRAKING SYSTEM. UPON FURTHER REVIEW ALL BRAKE LINES ON VEHICLE ARE EXHIBITING EXTREME CORROSION TO A SYSTEM THAT SHOULD NOT BE RUSTING.

BRAKE LINE FAILURE. I HAD COMPLETE BRAKE LINE FAILURE WHILE COMING TO A STOP AT A BUSY ROAD. I WAS LUCKY I WAS ABLE TO HONK MY HORN AND GO THROUGH THE LIGHT. I DRIVE THIS TRUCK ALMOST EVERY DAY AND HAD THIS HAPPENED ON MY NORMAL DAILY COMMUTE THIS COULD HAVE BEEN A DISASTER. IT IS RIDICULOUS THAT STAINLESS STEEL LINES WERE NOT USED ON SUCH A VITAL PART OF THE VEHICLE. NOW I AM LOOKING AT A LOT OF MONEY TO REPLACE ALL THE LINES. I DO NOT HAVE A BILL TO UPLOAD AT THIS TIME AS THE REPAIR WORK HAS NOT BEEN COMPLETED YET.

AT LOW SPEEDS WHEN A PERSON HIT THE BRAKES THE ABS ENGAGES AND THE VEHICLE WILL NOT STOP. ALL EQUIPMENT IS ORIGINAL AND IS NOT DUE TO RECALL REGARDING AFTERMARKET EQUIPMENT. LOCAL GARAGE SAYS THIS IS A PROBLEM WITH CORRODED SPEED SENSER. MY PROBLEM IS I ALMOST RAN THROUGH MY HOUSE THE FIRST TIME THIS HAPPENED. ANOTHER PROBLEM IS THE BRAKE LINES ON THESE TRUCKS CORODE AND BREAK WITHOUT NOTICE. THIS HAS NOTHING TO DO WITH PREVIOUS PARAGRAPH AS I REPLACED THEM AND ABS IS STILL MESSED UP. CHEVROLETS INFERIOUR PARTS USAGE REGARDING BRAKE LINES CAUSE THEM TO BURST PREMATURELY. I ALSO HAVE SEVERAL FRIENDS WITH IDENTICAL TRUCKS WHO ALL REPORT THE SAME PROBLEM. BOTH PROBLEMS ARE ONGOING PROBLEMS. I FIXED THE BRAKE LINES BUT I HAD TO REMOVE THE ABS MODULE TO KEEP THE ABS FROM ENGAGING AND CAUSING AN ACCIDENT.

ON CERTAIN VANS EQUIPPED WITH SURE-LOK WHEELCHAIR SECUREMENT SYSTEMS, THE SPROCKET TEETH OF THE RETRACTOR ASSEMBLY IS OUT OF ALIGNMENT.
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE WHEELCHAIR MAY NOT BE ADEQUATELY SECURED POSSIBLY RESULTING IN INJURIES TO A WHEELCHAIR OCCUPANT.
Remedy: DEALERS WILL INSPECT AND REPLACE THE WHEELCHAIR SECUREMENT RETRACTORS AS NECESSARY. SURE-LOK WILL HANDLE THE REPAIRS FOR THIS CAMPAIGN. OWNERS SHOULD CONTACT SURE-LOCK AT 1-908-231-1804 OR MOBILITYWORKS AT 1-800-769-8267.
VEHICLE DESCRIPTION: CERTAIN 2-WHEEL DRIVE PICKUP TRUCKS FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THE PROBLEM WAS CAUSED BY A COMPUTER ERROR THAT RESULTED IN THE CERTIFICATION LABEL LISTING TIRE SIZE AND INFLATION PRESSURE INFORMATION THAT DIFFER FROM THE TIRE SIZE AND THE INFLATION PRESSURE INFORMATION FOR THE TIRES ON THE VEHICLE. IF THE VEHICLE OWNER OR SOMEONE SERVICING THE VEHICLE INFLATES THE TIRES ACCORDING TO THE PRESSURE SPECIFIED ON THE LABEL VERSUS THE APPROPRIATE PRESSURE FOR THE TIRES, THE TIRES COULD BE UNDER-INFLATED OR OVER-INFLATED DEPENDING ON THE TIRES MOUNTED ON THE VEHICLE.
Consequence & remedy
Consequence: IF THE TIRES ARE UNDER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE, AND THE TIRE COULD DEGRADE TO A POINT OF ALLOWING SUDDEN AIR LOSS. IF THE TIRES ARE OVER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE AND INCREASE SUSCEPTIBILITY TO ROAD HAZARD DAMAGE. IF SUDDEN AIR LOSS OR A ROAD HAZARD CAUSES DAMAGE TO A TIRE, CONTROL OF THE VEHICLE COULD BE ADVERSELY AFFECTED AND COULD RESULT IN A VEHICLE CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH A NEW LABEL AND INSTALLATION INSTRUCTIONS. HOWEVER, A DEALER CAN INSTALL THE LABEL IF THE OWNER SO DESIRES. OWNER NOTIFICATION BEGAN MAY 31, 2001. OWNERS WHO DO NOT RECEIVE THE LABEL AND INSTALLATION INSTRUCTIONS WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

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.
