WHILE DRIVING AT APP 50MPH I TRIED TO BRAKE TO AVOID A VEHICLE WHICH PULLED OUT IN FRONT OF ME AND MY PEDAL WENT ALL THE WAY TO THE FLOOR. TO MY HORROR I HAD NO BRAKES!!!!!! LUCKILY MY 2002 GMC IS A 5 SPEED MANUAL TRANSMISSION AND I WAS ABLE TO DOWN SHIFT TO AVOID AN ACCIDENT. USING MY TRANSMISSION AND FINALLY MY EMERGENCY BRAKE (WHICH RUSTED THROUGH THE YEAR BEFORE AND COST OVER $300. TO REPAIR)) I WAS ABLE TO PULL TO THE SIDE OF THE ROAD AND SAFELY STOP. MY AUTO WAS TOWED TO A LOCAL REPAIR SHOP WHERE THE MECHANIC SHOWED ME THE RUSTED THROUGH BRAKE LINES. IT COST ME OVER $2,000 FOR REPAIRS. *TR

TL* THE CONTACT OWNS A 2002 GMC SIERRA 1500. THE CONTACT STATED THAT THE ANTI LOCK SYSTEM BRAKING SYSTEM MALFUNCTIONED AT VARIOUS SPEEDS. THE BRAKES ENGAGED INDEPENDENTLY MAKING IT DIFFICULT TO DRIVE THE VEHICLE. THE VEHICLE WAS INSPECTED BY MECHANIC WHO FOUND CORROSION IN THE ANTI LOCK BRAKING SYSTEM SENSOR. THE BRAKING SYSTEM WAS REPLACED. THE FAILURE RECURRED SEVERAL TIMES. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 95,000. THE CURRENT MILEAGE WAS 119,000.

I HAVE A 2002 GMC SIERRA SLE 1500 EXTENDED CAB PICK UP. I HAD THE TRUCK ON RAMPS. WHEN I BACKED OFF OF THE RAMPS, I HAD TOTAL BRAKE FAILURE. SERVICE AND PARKING BRAKES. I COULD NOT STOP OR EVEN SLOW DOWN. THE TRUCK PROCEEDED DOWN A HILL BACKWARDS AND INTO A DITCH. THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR. I IMMEDIATELY PUSHED THE PARKING BRAKE TO THE FLOOR. NO BRAKES AT ALL. AFTER FARTHER INVESTIGATION, FOUND THE HYDRAULIC BRAKE LINE THAT RUNS ALONG THE FRAME RAIL TO THE BACK BRAKES COMPLETELY CORRODED AND ALL FLUID LEAKING OUT. BRAKE LINE ALMOST CORRODED INTO TWO PIECES. THE PARKING BRAKE SHOES HAVE WORN DOWN TO METAL ON THE BACK OF THE SHOE. THIS IS THE SECOND SET OF PARKING BRAKE SHOES I HAVE REPLACED IN 70,000 MILES. THE VEHICLE HAS BEEN WELL MAINTAINED AND THESE TWO ISSUES SHOULD NOT BE HAPPENING. I HAVE READ THAT THERE IS AN ONGOING INVESTIGATION INTO THE CORRODING BRAKE LINES AND A RECALL ON PARKING BRAKES, BUT ONLY ON STANDARD TRANSMISSION VEHICLES. MINE IS AN AUTOMATIC TRANSMISSION. HOW MANY MORE DAMAGED VEHICLES AND INJURIES OR DEATHS DOES IT TAKE FOR THE INVESTIGATION TO TURN INTO A RECALL? *TR

I WAS APPROACHING A STOP SIGN AT THE END OF MY STREET AND WHEN I APPLIED THE BRAKES THE PEDDLE WENT TO THE FLOOR. I ROLLED TO A STOP IN A GRASSY AREA AND SAW BRAKE FLUID LEAKING FROM THE BASE OF THE VEHICLE. I BROUGHT IT IN TO MY MECHANIC AND HE SAID THE BRAKE LINES RUSTED OUT TO THE REAR BRAKES. HE REPLACED THE LINES FROM THE ABS PUMP TO THE REAR AXLE AND THE BRAKE LINES FROM THE REAR AXLE TO THE REAR CALIPERS. THE COST TO REPLACE THE SE LINES WAS $433.46. THIS IS THE SECOND TIME THIS HAS HAPPENED TO THIS VEHICLE SEE ODI NUMBER 10402034. *TR

I WAS AT MY LOCAL COFFEE SHOP DRIVE THRU. I LEFT THE DRIVE THRU AND AS I APPROACHED THE EXIT, ROLLING VERY SLOW I EXPERIENCED THE DREADED GM BRAKE FAILURE. MY FOOT WENT TO THE FLOOR. LUCKILY I WAS ABLE TO USE THE EMERGENCY BRAKE BEFORE INVOLUNTARILY MERGING ONTO A BUSY SECONDARY ROAD. I UNDERSTAND RUST IS INEVITABLE BUT ALL OF THE BRAKE LINES ARE BEYOND REPAIR ACCORDING TO MY MECHANIC - HE WILL NOT REPAIR THEM ONLY REPLACE THEM. MY BIGGER ISSUE IS THE FACT THAT SINCE 1967 ALL CARS & LIGHT TRUCKS USE A DUAL MASTER CYLINDER ENABLING THE VEHICLE TO STOP INCASE OF BRAKE FAILURE. MY GMC AND APPARENTLY OTHERS HAVE THE SAME ISSUE - THAT EVEN WHEN A LINE BLOWS THE TRUCKS WILL NOT STOP! THE DUAL MASTER DOES NOT DO WHAT IT IS DESIGNED TO DO! THIS COUPLED WITH THE FACT THAT I ALSO HAVE BEEN PLAGUED WITH ABS LOW SPEED PROBLEMS SINCE 60K I REALLY FEEL THAT GM ENGINEERS AND BEAN COUNTERS NEED TO AGREE ON SAFETY. CONSIDERING THAT BRAKE LINES OF THIRTY YEARS AGO ARE BETTER THAN LATE MODEL PRODUCTS WOULD IT REALLY BE THAT MUCH FOR THE FEDS TO REQUIRE STAINLESS STEEL BRAKE LINES? MY 2002 SIERRA LOOKS GOOD BUT THE UNDERSIDE (CHASSIS, SUSPENSION PARTS AND BRAKE LINES) ARE NOT GOOD. THIS TRUCK IS NOT A GOOD INVESTMENT AND IT IS DEFINITELY FULL OF SAFETY ISSUES. IF I WAS IN TRAFFIC I AM SURE THAT I WOULD NOT BEEN ABLE TO STOP WITHOUT AN ACCIDENT. WE AS CONSUMERS DO NOT NEED THIRD BRAKE LIGHTS AND USELESS ABS BRAKES. WE NEED BRAKES THAT WORK WHEN PRESSURE IS APPLIED TO THE PEDAL! *TR

ON MY 2002 GMC SIERRA 1500 EXTENDED CAB 2WD THE ABS AND BRAKE LIGHTS GO ON AND OFF. I HAD MY LOCAL GM DEALER ADDRESS THIS ON SEVERAL OCCASIONS THEY HAVE COME TO THE CONCLUSION THAT THE ABS BRAKE MODULE IS BAD. I ASKED IF THERE WERE ANY RECALLS ON THIS THEY SAID THEIR IS A BULLETIN OUT THAT THE GROUNDS COULD BE BAD SO I HAD THEM DO THIS FIX IT DID NOT CORRECT THE PROBLEM ALSO THEIR WAS A RECALL TO FIX THE SPEED SENSORS IN THE WHEELS WHICH THEY FIXED ALSO DID NOT FIX THE PROBLEM. I DECIDED TO GOOGLE THIS TYPE OF PROBLEM TO SEE IF OTHER PEOPLE HAD THIS SAME ISSUE I HAVE FOUND HUNDRED OF THOUSANDS OF PEOPLE WITH EXACT SAME ISSUE OR WERE IT HAS EVEN GOTTEN WORSE AND THE LIGHTS STAY ON ALL THE TIME. IT SEEMS TO AFFECT GM VEHICLES MADE FROM 1999 TO 2007 CARS AND TRUCKS BUT MOSTLY TRUCKS. TO ME THIS IS A BIG SAFETY ISSUE MOST PEOPLE DO NOT KNOW THAT WHEN BOTH OF THOSE LIGHTS ARE ON THEY HAVE NO ABS. I WAS LUCKY TO HAVE A GOOD SERVICE MANAGER WHO EXPLAINED THIS TO ME AND HOW OFTEN THIS PROBLEM OCCURS. THANK YOU. *TR

WHILE DRIVING DOWN THE HIGHWAY IN THE FAR RIGHT LANE. GOING ABOUT 60 MILES A HOUR WE HIT A PATCH OF BLACK ICE. THE VEHICLE STARTED TO FISHTAIL. THE DRIVER KEPT THE VEHICLE FROM SPINNING OUT AND DOING A 360. WE CROSSED OVER 3 LANES OF TRAFFIC, WITHOUT HITTING ANOTHER VEHICLE. WHEN THE TRUCK FINALLY GRIPED ON TO THE ROAD WE HAD NO WAY OF AVOIDING THE CENTER MEDIAN, A CONCRET WALL DIVIDER. UPON IMPACT NEITHER THE DRIVERSIDE OR THE PASSENGERSIDE AIRBAGS DEPLOYED. WE HIT THE WALL AT A 70 DEGREE ANGLE SO IT WAS PRETTY MUCH HEAD ON. WHY DIDN'T THE AIRBAGS DEPLOY??????? FROM READING OTHER POSTS ON OTHER SITES IT SOUNDS LIKE THIS HAPPENS A LOT. WHY ISN'T THERE A RECALL. APPARENTLY THERE IS SOMETHING WRONG AND IT'S UNSAFE. *TR ## VIN PASSED ## GMC, SIERRA, 1500, 2002 ##

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.
