EXTREME RUST ON UNDER CARRAGE OF VEHICLE. BRAKE LINES RUSTED OUT CAUSING BRAKE FAILURE FRAME RUSTED OUT AT REAR LEAF SPRINGS AND FRAME RAIL CROSS MEMBERS. REAR SHOCK HANGERS RUSTED OFF VEHICLE. FRAME RUSTED SO BAD THAT IT PROHIBITS TOUNG OF ANY TYPE OF TRAILER. TOYOTA HAD SAME PROBLEM AND THEY HAD TO DO A RECALL SO WHY HAS GM NOT HAD TO DO THE SAME THING. IT IS A VERY LARGE SAFETY ISSUE AFFECTING MANY VEHICLES ON THE HWY TODAY.

RUSTED BRAKE LINE BURST RESULTING IN COMPLETE BRAKE FAILURE. EVEN THE DUAL SYSTEM TO HAVE AT LEAST TWO FUNCTIONING BRAKES ALSO FAILED. GM USED SUBSTANDARD MATERIAL FOR THE LINES.

TYPICAL GM PRODUCT, REAR BUMPER RUST OUT, BRAKE LIKES RUSTED COMPLETELY OUT, REAR CROSS MEMBERS, FUEL TANK CROSS MEMBER HAS RUSTED OUT COMPLETELY ON PASSENGER SIDE WHERE THE SHOCK MOUNTS TO AND THE SAME FOR THE REAR CROMMM MEMBER WHERE THE SHOCK MOUNTS TO ON THE DRIVER SIDE. I MEAN THE FUEL TAN CROSS MEMBER HOLDS THE TANK IN PLACE AND IF THAT TANK DROPPS THEN I'D ASSUME THAT IT WOULD BE A SAFETY ISSUE. ATLEAST I HOPE SO.

I WAS DRIVING MY TRUCK AND NOTICED THE ABS LIGHT COME ON AND A HUMMING SOUND FROM UNDERNEATH THE VEHICLE. I STOPPED THE VEHICLE AND TURNED IT OFF INCLUDING REMOVING THE KEY FROM THE IGNITION, AND A MOTOR NEAR THE ABS SYSTEM KEPT RUNNING. I THEN PRESSED ON THE BRAKE PEDAL AGAIN AND ONE OF THE BRAKE LINES RUPTURED. I LOOKED AT ALL THE LINES AND THEY ARE ALL SEVERALLY RUSTED AND ABOUT TO BLOW TOO. AFTER READING ABOUT THIS ON THE INTERNET THIS IS APPARENTLY A HUGE ISSUE WITH A LOT OF GM VEHICLES MADE BETWEEN 1999 AND 2003. I ENDED UP SPENDING $800 TO HAVE ALL THE BRAKE LINES REPLACED SO THE VEHICLE IS SAFE AGAIN. I AM AMAZED THIS HAS NOT BEEN RECALLED OR AT LEAST HAD AN OFFER FOR A DISCOUNTED REPAIR. I AM GLAD THAT I DIDNT GET INTO AN ACCIDENT TO FIND THIS ISSUE LIKE A LOT OF STORIES I READ. I GUESS IT WILL JUST TAKE A FEW DEATHS BEFORE IT IS RECALLED.

ALL OF THE STEEL BRAKE LINES ARE LEAKING AND MY BRAKES AREN'T WORKING. I WAS DRIVING UP MY ROAD AND THE BRAKES WENT OUT. I HAD TO DRIVE VERY SLOWLY TO GET HOME. I'VE CALLED SEVERAL GARAGES AND THEY ALL TELL ME THAT ALL OF THE SILVERADOS HAVE BAD BRAKE LINES THAT RUST THROUGH AND THEY CHANGE THEM ALL OF THE TIME. SOME OF THE GARAGES TELL ME THEY SHOULD HAVE BEEN RECALLED AND GM SHOULD PAY FOR THEM. WILL GENERAL MOTORS PAY FOR THE REPLACEMENT OF THESE BRAKE LINES? I RECENTLY BOUGHT THIS TRUCK AND THE BRAKES AREN'T WORKING. I HAVE A 2000 FORD RANGER THAT I BOUGHT NEW AND HAVE NEVER HAD ANY BRAKE PROBLEMS , IT STILL HAS THE ORIGINAL BRAKE LINES. THEY SHOULDN'T BE ABLE TO USE STEEL BRAKE LINES ON CARS. THEY SHOULD BE A RUST FREE MATERIAL. HOW MANY PEOPLE HAVE BEEN KILLED BECAUSE THEY CAN'T STOP BECAUSE THE BRAKE LINES BLEW OUT. THAT'S CRAZY. CAN'T YOU MAKE THE CAR COMPANIES USE CORROSION RESISTANT BRAKE LINES WHEN THEY BUILD THESE VEHICLES? CAN YOU HELP ME WITH THIS? IT'S GOING TO COST $500 TO REPLACE ALL OF THE LINES.

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.
