I HAD A BRAKE LINE FAILURE UNDER A HARD BRAKING CONDITION (FIRM, BUT NOT PANIC STOP). THE HARD LINE FROM THE ABS PUMP TO THE REAR AXLE FAILED JUST ABOVE THE FLEX HOSE COUPLING.

I HAD A BRAKE LINE FAILURE UNDER A HARD BRAKING CONDITION (FIRM, BUT NOT PANIC STOP). THE HARD LINE FROM THE ABS PUMP TO THE REAR AXLE FAILED JUST ABOVE THE FLEX HOSE COUPLING. I HAD BELIEVE IT TO BE THE FLEX HOSE AT FIRST. UPON INSPECTION, THE HARDLINE AND FITTING TO THE FLEX LINE AT THE REAR AXLE HAS BECOME SO CORRODED AS TO NEARLY BE INDISTINGUISHABLE. BRAKING CONTROL WAS MINIMAL. THE PEDAL WENT TO THE FLOOR EVEN WITH THE FRONT CIRCUIT STILL INTACT. EVEN THEN, IT COULD NOT COMPLETELY STOP THE VEHICLE AND I WAS FORCED TO USE THE PARKING/EMERGENCY BRAKE. HAD I BEEN TOWING AT THE TIME, I AM CONVINCED IT WOULD HAVE BEEN CATASTROPHIC. *TR

I WAS TRYING TO COME TO A STOP AT A RED LIGHT WHEN PRESSING ON MY BRAKE PEDAL IT WENT COMPLETELY TO FLOOR. LUCKILY THERE WAS NO ONE IN FRONT OF ME & WAS ABLE TO TURN THE TRUCK INTO THE NEARBY STORE PARKING LOT. WHEN I GOT THE TRUCK HOME & TOOK A LOOK TO SEE WHAT THE PROBLEM WAS, I SEEN THAT THERE WAS A BRAKE LINE, ON THE DRIVERS SIDE, UNDER THE HOOD, THAT HAD A HOLE IN IT & WAS SPRAYING FLUID EVERYWHERE. THE LINE ALSO LOOKED TO BE RUSTED. TO MAKE NOTE THE TRUCK WAS ABLE TO COME TO A STOP WHEN DRIVING VERY SLOWLY, HOWEVER, I WAS TRAVELING AT ABOUT 35 MPH WHEN TRYING TO STOP & TRAVELED (JUST GUESSING) ABOUT 30 TO 40 YARDS TO THE RED LIGHT & WAS STILL UNABLE TO STOP. *TR

THERE HAVE BEEN CONSISTENT PROBLEMS WITH THIS VEHICLE SINCE WE BOUGHT IT ON JUNE 18, 1999. THE FRAME AND SUSPENSION LOOKED AS IF IT WAS DRIVEN IN A SALT BATH - TOTALLY RUSTED. SAW THIS RIGHT AFTER BUYING IT BUT THE DEALER WOULD NOT DO ANYTHING. WE HAVE NEVER RECEIVED ANY RECALL NOTICES. THE WORSE THING THAT HAPPENED WAS WHEN THE BRAKES WENT OUT ON MY WIFE WHILE DRIVING ON THE EXPRESSWAY ABOUT AN HOUR AWAY FROM HOME. THE FRONT SHOCKS WERE BAD WITH 553 MILES. THE EGR VALVE WENT OUT THE FIRST WEEK WE HAD THE TRUCK. THE BRAKE LINES, BRAKE SENSORS AND ROTORS HAVE BEEN REPLACED 7 TIMES. AS OF TODAY THIS TRUCK HAS 52,000 MILES AND IT IS 15 YEARS OLD. WE WILL NEVER BUY ANOTHER GM VEHICLE. DOES SOMEONE HAVE TO GET KILLED OR INJURED BEFORE ANYTHING IS DONE? *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.
