GM RECALLED THIS VEHICLE IN 2006 DUE TO CORROSION OF FRONT ABS SPEED SENSOR (CHEVY RECALL #05068C: PRODUCT SAFETY - FRONT WHEEL SPEED SENSOR CORROSION). MY ABS ARE PULSING AT VERY LOW SPEED - STOP SIGNS/LIGHTS/PARKING ETC. THIS IS CHARACTERISTIC OF THE CORROSION ISSUE. I'VE BEEN TOLD I HAD THE REPAIR (I DON'T DOUBT IT - THERE WERE TWO - ONE FOR REAR PARKING BRAKE AND ONE I DIDN'T REALLY RESEARCH - I JUST TOOK IT IN - I ASSUME THAT WAS THIS ISSUE - SENSOR CORROSION). I KNOW THE VEHICLE IS 13 YEARS OLD. HOWEVER, I'M THE ORIGINAL OWNER, AND IT HAS ONLY 87,000 MILES. IT WAS ALWAYS GARAGE KEPT. IT LIVED IN WI FOR ITS FIRST 11 YEARS, AND NOW RESIDES ON THE SOUTHERN OR COAST. MY QUESTION: ONCE AN OEM MAKES A SAFETY REPAIR UNDER RECALL, IS THERE AN OBLIGATION THAT IT SOLVES THE PROBLEM? OR IS IT THE USUAL 1 YEAR PARTS AND LABOR THING? THANKS! *TR

I BEGAN TO PUMP THE BRAKES QUICKLY HOPING THE SYSTEM WOULD SEND FLUID TO THE OTHER SET WHICH IT DID NOT. IN ORDER TO PREVENT IMPACTING THE VEHICLE IN FRONT OF ME OR THE DISABLED VEHICLE, I HAD TO SEND THE VEHICLE ACROSS ONCOMING TRAFFIC, LAUNCH OVER A ROADSIDE DITCH AND COME TO A STOP IN A CORN FIELD. THE FAILURE WAS A PINHOLE BLOWOUT UNDER THE DRIVERS SIDE DOOR WHERE THE BRAKE WERE COMPLETELY RUSTED THROUGH. *TR

WHILE DRIVING ON A RESIDENTIAL STREET I ATTEMPTED TO APPLY THE BRAKES AND THE BRAKE PEDAL WENT TO THE FLOOR. AFTER ABOUT 20 FEET THE TRUCK DID STOP WITH THE BRAKE PEDAL ALMOST ON THE FLOOR. THE TRUCK HAD TO BE TOWED AND THE FRONT BRAKE LINES WHERE RUSTED AND LEAKING AND REPLACED. THE REAR LINES ARE ALSO RUSTED AND NEED TO BE REPLACED.THE TOTAL COST IS ABOUT $500.00. I HAVE HAD TO REPLACE THE FULE LINE AS IT ALSO RUSTED AND LEAKED, THAT COST WAS $900.00. APPARENTLY GM HAS HAD NUMEROUS PROBLEMS WITH THIS. IN OVER 40 YEARS I HAVE NEVER SEEN LINES RUST THROUGH LIKE THIS.IT IS A SEROIUS PROBLEM AND COULD HAVE RESULTED IN A MAJOR ACCIDENT IF THE AREA HAD BEEN MORE CONGESTED AND SPEED GREATER.GM SHOULD BE PUTTING QUALITY MATERIAL ON SUCH A VITAL SYSTEM. ALSO THE REAR BRAKES WHERE ALMOST NON-EXISTENT DUE TO THE GM ABS DESIGN. THIS GIVES NO BRAKING ABILITY AND SHOULD NOT BE THAT WAY.AS FAR AS SAFETY GOES THIS SHOULD BE A NUMBER ONE ISSUE AS BRAKE FAILURE CAN BE LETAL, GAS LEAKING ISNT VERY SAFE EITHER.

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.
