PARKING BRAKE FAILURE ON 2001 CHEVROLET 1500 SERIES PICKUP. CONSUMER REPORTS MAGAZINE PUBLISHED A SAFETY ALERT FOR THIS SAME PROBLEM STATING THAT 1999-2005 MODELS ARE AT DANGER BECAUSE OF FRICTION THAT COULD MAKE THE PARKING BRAKE INEFFECTIVE. OUR UNDERSTANDING IS A RECALL HAS BEEN ISSUED FOR THE MANUAL TRANSMISSIONS, BUT NOT FOR THE AUTOMATIC TRANSMISSIONS WHICH IS WHAT WE HAVE. WE TOOK ONE OF THE TRUCKS FROM OUR BUSINESS FLEET (COMPRISED OF 15-20 CHEVROLET 1500 SERIES PICKUP TRUCKS) TO BE INSPECTED TODAY AND IT FAILED BECAUSE OF THIS PARKING BRAKE FAILURE. THERE WAS ANOTHER GENTLEMAN AT THE INSPECTION PLACE WITH A CHEVROLET 1500 TRUCK WHILE WE WERE THERE, AND HIS TRUCK FAILED FOR THE PARKING BRAKE ALSO. WE CONTACTED MORITZ CHEVROLET, A LOCAL DEALERSHIP, AND THEY STATED THAT THEY SEE LARGE #S OF VEHICLES COME IN FOR THIS SAME PROBLEM. THE AUTO INSPECTION ESTABLISHMENT SAID THEY SAME THING - THEY FAIL COUNTLESS NUMBERS OF 1999-2005 CHEVROLET 1500 PICKUP TRUCKS FOR PARKING BRAKE FAILURE. IT IS GOING TO COST US $200 TO HAVE THIS REPAIRED. CHEVROLET CLEARLY KNOWS THAT THERE IS A PROBLEM, AND A RECALL NEEDS TO BE ISSUED AT ONCE. THIS IS A SAFETY HAZARD. *JB

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.
