BRAKE FAILURE FOR THE SECOND TIME ON THE VEHICLE. ORIGINAL BRAKE LINES WERE REPLACED 7 OR 8 YEARS AGO DUE TO FAILURE AT MY OWN COST (RUSTED LINES, LEADING THEM TO FAIL AS THE BRAKES WERE APPLIED), ALL LINES WERE REPLACE WITH GM REPLACEMENT LINES BY A QUALIFIED TECHNICIAN. ORIGINAL FAILURE RENDERED THE BRAKES 0% OPERATIONAL, GRAVITY (UPHILL) WAS THE ONLY THING THAT STOPPED THE VEHICLE. THE MOST RECENT FAILURE (ON JULY 29, 2017) AFFECTED THE BRAKE LINE RUNNING TO THE FRONT-RIGHT CALIPER, LINE FAILED WHERE IT CROSSED OVER THE SKID PLATE NEAR THE CENTER-LINE OF THE VEHICLE UP FRONT BY THE LOWER RADIATOR SUPPORT. LINE FAILED DUE TO CORROSION. REAR BRAKES APPEAR TO BE WORKING BUT ARE NOT SUFFICIENT TO STOP THE VEHICLE IN A SAFE MANNER. NO ACCIDENT OCCURRED, LINE FAILED AS APPROACHING A LIGHT TURNING RED WHILE GOING UPHILL, ROLLED THROUGH THE INTERSECTION PRIOR TO THE LIGHT TURNING GREEN FOR CROSSING TRAFFIC AND WAS ABLE TO STOP THE VEHICLE AS IT DRIFTED TO A STOP UPHILL. THE QUALITY OF THE GM BRAKE LINES ARE VERY SUSPECT TO SAY THE LEAST. THE BRAKE LINES ARE DANGEROUS AND SEEM TO BE MORE SUSCEPTIBLE TO CORROSION THAN ANY OTHER BRAKE LINE ON ANY OTHER VEHICLE I'VE EVER OWNED, OR ANY OF MY FRIENDS OR FAMILY HAVE EVER OWNED. I CAN ONLY IMAGINE IF THE LINES FAILED UNDER DIFFERENT CIRCUMSTANCES (WHILE TOWING THOUGH MOUNTAINS WHILE GOING DOWNHILL FOR EXAMPLE, THIS WOULD BE A LIFE-THREATENING SITUATION). PLEASE DETERMINE IF THESE LINES ARE FAULTY FOR THE SAKE OF OTHERS WITH THESE VEHICLES, AND THE SAKE OF OTHER MOTORISTS THAT COULD BE IMPACTED WHEN THE BRAKES ON THIS LARGER VEHICLE FAIL. IF THEY ARE FOUND TO BE FAULTY OWNERS SHOULD BE NOTIFIED THAT THESE BRAKE LINES ARE SUBPAR, AND THAT THE MANUFACTURER'S REPLACEMENT LINES ARE ALSO SUBPAR.
MY GAS NEEDLE STOP WORKING AND I KNOW THREE OTHER PEOPLE WITH THE SAME PROBLEM
BRAKE LINE RUNNING ON TOP OF FRAME FROM MASTER CYL TO ABS HAS CORRODED TO THE POINT OF FAILURE. IT HAS RUSTED THROUGH AND LEAKS BRAKE FLUID. BRAKES HAVE FAILED. THIS VEHICLE HAS NEVER LEFT FLORIDA AND IS STILL HELD BY ORIGINAL OWNER.

WE WERE TRAVELING WEST ON 495 HEADING TO GEORGETOWN HOSPITAL IN DC TAKING A FRIEND FOR HER WEEKLY KIDNEY TRANSPLANT CHECKUP FROM BALTIMORE MD. THE TRAFFIC HAD SLOWED TO A STOP AS I HIT MY BRAKES AND THEY WENT TO THE FLOOR WITH MINUTE STOPPING POWER . HAD I BEEN IN THE NEXT LANE OVER IT WOULD HAVE BEEN A WIPE OUT AS I WOULD HAVE REAR ENDED THE STOPPED TRAFFIC. I WAS IN THE CURB LANE AND GOT INTO THE SHOULDER. BRAKE LINES ARE TOTALLY CORRODED, RUSTED AND JUST CRUMBLING.. I NOTICED GM KNOWS ABOUT THE PROBLEM BUT REFUSES TO DO ANYTHING. WILL THEY WAIT UNTIL A FATALITY HAPPENS BEFORE THEY WARN THE PUBLIC OF THIS PROBLEM.. MANY OF THESE VEHICLES STILL ON THE ROAD.. *TR

BRAKE LINES RUSTED OUT AND CAUSED TRUCK TO NOT BE ABLE TO STOP AND ALMOST CAUSED AN ACCIDENT. FIRST LINE WENT ABOUT 2 MONTHS AGO AND WAS REPAIRED. I ASSUMED THAT THIS WAS A SINGULAR INCIDENT AND THE REPAIR WAS FINE, AND I WOULD HAVE NO OTHER PROBLEMS. NOW, A DIFFERENT BRAKE LINE WENT. SAME EXACT PROBLEM...RUSTED OUT APPEARS THAT ALL OF THE LINES ARE AT ISSUE AND ALL OF THEM MUST BE REPLACED. I WAS LUCKY AS I HAD JUST COME OFF THE INTERSTATE HIGHWAY WHERE I WAS DOING SPEEDS OF 70MPH AND RELYING ON MY BRAKES AS WOULD BE NORMAL. JUST AS I GOT OFF THE HIGHWAY AND PULLED INTO WORK, THE LINE BLEW OUT COMPLETELY AND MY PEDAL WENT TO THE FLOOR. I HAD NO BRAKES AT ALL...NOTHING. LUCKILY, I WAS IN THE PARKING LOT, AND GOING SLOW ENOUGH AND I THOUGHT QUICKLY AND USED MY EMERGENCY BRAKES AND STOPPED. HAD THE BRAKE LINE GONE OUT JUST TWO MINUTES EARLIER, OR ABOUT TWO OR THREE BRAKE PEDAL PRESSES BEFORE, I WOULD HAVE BEEN IN A SERIOUS ACCIDENT. *TR

Status: closed (inferred from source dates) · Parking Brake
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.
