IllustrationABS ACTIVATING AT LOW SPEEDS WAS BROUGHT IN UNDER WARRANTY AND REPAIRED ONCE ALREADY. PROBABLY 2004. NOW SAME THING AGAIN 2008. VERY DANGEROUS WHEN YOU STEP ON BRAKE AND ABS ACTIVATES FOR NO REASON (OTHER THAN POOR DESIGN) AT LOW SPEED AND INCREASES YOUR STOPPING DISTANCE BY 10 PLUS FEET. *TR

ANTILOCK BRAKES ON 2002 GMC SIERRA TRUCK ACTIVATE FOR NO REASON AT SPEEDS OF 5MPH OR LESS MAKING THE VEHICLE UNSAFE TO DRIVE. THERE WAS A RECALL ON THE SENSORS FOR THIS REASON. I HAD MY SENSORS "TAKEN CARE OF" AND AFTERWARDS STARTED EXPERIENCING THIS EXACT PROBLEM. I WAS TOLD THAT THE HUBS ARE BAD AND THIS IS WHY THE ANTI LOCKS ARE COMING ON. THE SENSORS CAN NOT READ THE HUB "CORRECTLY". THE HUBS, WHICH ARE NOT A WEAR ITEM, CAN BE REPLACED FOR $1000. THIS IS ON A 2002 PICK UP TRUCK WITH 46,000 MILES ON IT AND IS GARAGE KEPT. THE HUBS ARE A NON WEAR ITEM. POOR ENGINEERING IS THE CULPRIT OF THIS PROBLEM. THE HUBS SHOULD BE REPLACED JUST LIKE THE SENSORS WERE. I WAS ALSO TOLD THAT ON MY GMC TRUCK I CANNOT HAVE THE ANTILOCK BRAKES DEACTIVATED. AS A RESULT, I HAVE TO SPEND THE $1000 TO MAKE MY TRUCK SAFE TO DRIVE. PROBABLY 40,000 MILES IN THE FUTURE I CAN REPLACE THE HUBS AGAIN FOR $1000. $1000 TO REPLACE A NON WEAR ITEM. ANTILOCK BRAKES ARE ON A VEHICLE TO MAKE THE VEHICLE SAFER. THE ANTILOCKS ON MY GMC MAKE THE VEHICLE UNDRIVABLE BECAUSE OF BEING UNSAFE. IT SHOULD BE POSSIBLE TO DEPEND ON YOUR BRAKES TO MAKE YOU STOP. WITH MY VEHICLE I CAN'T STOP. THIS IS NOT A WEAR ITEM THAT IS CAUSING MY PROBLEM. THIS IS POOR ENGINEERING! THIS SHOULD BE COVERED UNDER A RECALL, SAME AS THE SENSORS WERE COVERED UNDER A RECALL. GMC WILL COVER THE SENSORS BUT NOT WHAT THE SENSORS ARE LOOKING AT. *TR

THERE IS ABNORMAL BRAKE ROTOR DETERIATION AND RUSTING DUE TO POOR MANUFACTURING OR STEEL FORMULAS WHICH RUST ACCERLERATES AND WEARS DOWN THE PADS UNEVENLY. I HAVE WORKED ON BRAKES ON MANY AUTOS AND A FEW TRUCKS I'VE OWNED OVER THE LAST FEW DECADES AND NEVER HAVE SEEN SUCH RUSTING AND SURFACE FLAKING OF THE DISK ROTOR ON MY VIHICLE. I HAD MY DEALER LOOK AT THE ROTORS AND THEY AGREED IT MAY BE A BIT EXCESSIVE. I HAVE TO REPLACE ALL FOUR ROTORS DUE TO POOR QUALITY AND UNREPAIRABLE ROTORS. THE ROTORS LOOK LIKE THEY CAME OFF A 20 YEAR OLD TRUCK....THIS IS A SAFETY AND QUALITY PROBLEM THAT SHOULD BE LOOKED INTO. THANK YOU

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.
