WHILE TOWING A HEAVY TRAILER AT 30 MPH, I ATTEMPTED TO STOP AT A RED LIGHT. WITH NO BRAKE WARNING LIGHT, THE BRAKE PEDAL WENT TO THE FLOOR AND I HAD NO BRAKING WHATEVER. I STOMPED ON THE EMERGENCY BRAKE AND NOTHING HAPPENED. I WAS ABLE TO TAKE A HARD RIGHT TURN TO AVOID A COLLISION AND COASTED TO A STOP. LOOKING DOWN, THERE WAS A TRAIL OF BRAKE FLUID LEADING TO A LARGE PUDDLE UNDER THE DRIVER'S DOOR. LOOKING UNDER THE TRUCK REVEALED THAT INCREDIBLY RUSTED BRAKES LINES HAD BURST, DRAINING THE ENTIRE CONTENTS OF THE FLUID RESERVOIR. CLOSER INSPECTION SHOWED THAT EVERY FOOT OF BRAKE LINE UNDER THE TRUCK WAS IN SIMILAR CONDITION! AFTER TOWING IT HOME, I DISCOVER WHY THE E-BRAKE FAILED; THE CABLE WAS RUSTED SOLID. I HAD TO ORDER A COMPLETE BRAKE LINE KIT AND SPENT THE ENTIRE WEEKEND REPLACING THEM. IT WAS THEN THAT I FOUND OUT THAT THOUSANDS OF OWNERS HAVE BEEN FIGHTING GM TO MAKE GOOD ON THIS DEFECT. WE NARROWLY ESCAPED A SERIOUS ACCIDENT AND SPENT A CONSIDERABLE AMOUNT OF TIME AND MONEY, BESIDES HAVING TO BORROW A VEHICLE TO GET TO WORK FOR A WEEK.

1. ABS ACTIVATION AT LOW SPEEDS WHEN WHEELS ARE NOT SLIPPING. WHEN SLOWING THE TRUCK DOWN THE VEHICLE ABS ACTIVATES PREVENTING THE VEHICLE FROM STOPPING UNLESS YOU EITHER RELEASE AND REAPPLY THE BRAKE OR COLLIDE WITH THE OBJECT IN FRONT OF YOU. 2. BRAKE LINE FAILURE DUE TO RUST AND CORROSION. WHILE TRAVELING DOWN THE HIGHWAY PULLING A 4,000 POUND TRAILER THE BRAKE LINE RUPTURED UNDER THE DRIVERS DOOR CAUSING A LOSS OF BRAKES. I HAD THOUGHT THE BRAKE SYSTEM WAS CROSSED TYPE SYSTEM AND THAT I SHOULD HAVE HAD BRAKE PRESSURE ON THE REMAINING INTACT LINES BUT THE PEDAL WAS SO SOFT I DON'T BELIEVE THERE WERE ANY BRAKES. VERY DISAPPOINTED IN THE BRAKE SYSTEM UNDER EMERGENCY FAILURE.

THE TRAFFIC LIGHT TURNED TO YELLOW AND I TRIED TO STOP BUT THE PEDDLE WENT ALL THE WAY TO THE FLOOR.THIS TRUCK HAD SUCH BAD BRAKE LINES THAT WHEN BLEEDING THE BRAKE LINES FOR THE FRONT LINE ANOTHER LEAK STARTED OUT ONE OF THE REAR LINES. THIS IS A CLEAR SAFETY CONCERN FOR OWNERS OF A CHEVROLET SILVERADO.

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.
