BRAKES FAILED SUDDENLY. WE WERE LUCKY THAT WE WERE ONLY GOING ABOUT 20 MPH. BRAKE LIGHT DID NOT COME ON AND STILL DOES NOT SHOW A PROBLEM. RUSTED BRAKE LINE RUPTURED AND BRAKE FLUID COMES OUT WHEN THE BRAKES ARE APPLIED. I JUST SOLD A TOYOTA 1995 4WD THAT HAS BEEN EXPOSED TO THE SAME ENVIRONMENT AND THERE IS VERY LITTLE RUST COMPARED TO THE CHEVROLET. IT LOOKS LIKE TO ME THAT ALL THE LINES SHOULD BE REPLACED. I HAVE NOT YET HAD IT REPAIRED. THIS COULD HAVE CAUSE A VERY BAD ACCIDENT. WE ARE NOT DRIVING UNTIL IT IS REPAIRED. *TR

VEHICLE WAS TOWING TRAILER IN HAYFIELD AND BRAKES WENT OUT. THE VEHICLE WAS IN 4 WHEEL DRIVE LOW AND IN 1ST GEAR. MY HUSBAND GOT IT BACK TO THE BARN WHICH WAS ABOUT 1/4 MILE AWAY AND THEN IT HAD TOTAL BRAKE FAILURE. THE BRAKE LIGHT NEVER CAME ON AND OUR BRAKES WERE NOT OLD. WE FOUND A LEAK IN OUR MAIN BRAKE LINE AND MY HUSBAND PINCHED THE LINE OFF SO WE WOULD HAVE SOME FRONT BRAKE SO WE COULD GET THE TRUCK HOME SO WE COULD WORK ON IT. HE REMOVED THE LINE AND IT WAS SO BADLY RUSTED, THAT IT HAD GOTTEN 3 MAJOR HOLES IN THE LINE AND WE DID HAVE MAJOR BRAKE FAILURE. THE LINE IS WAS VERY RUSTY IN SEVERAL PLACES, BUT THE WORST IS WHERE THE CAB AND BED COME TOGETHER. UPON RESEARCHING WE HAVE FOUND THAT THIS MODEL HAS A PROBLEM WITH THE LINE RUSTING AND CAUSING BRAKE FAILURE. WE REGULARLY HAUL HORSES TO HORSE SHOWS AND HAUL OTHER HEAVY LOADS ON THE ROAD. I CAN ONLY IMAGINE WHAT MIGHT HAVE HAPPENED HAD WE BEEN ON A MAJOR HIGHWAY AND THIS HAPPENED. WE BOUGHT OUR TRUCK NEW AND MAINTAIN IT WELL. WE HAVE NEVER HAD LINES RUST ON ANYTHING LIKE THIS AND NEVER HAD COMPLETE BRAKE FAILURE. WE FEEL THAT THIS IS A SAFETY ISSUE THAT NEEDS TO BE ADDRESSED. IT IS VERY EXPENSIVE REPAIR, BUT IT IS SERIOUS. WE MAKE SURE WE HAVE SEAT BELTS, AIR BAGS, EMISSIONS ARE LOW AND I FEEL THAT BRAKE LINES SHOULD BE MADE OUT OF A MATERIAL THAT WILL NOT RUST OUT AND CAUSE A MAJOR FAILURE. THIS HAPPENED SO FAST - WE HAD BRAKE AND THEN WE DIDN'T HAVE BRAKE. I THANK GOD THAT WE WERE IN THE HAYFIELD. WE HAVE TALKED TO SEVERAL PEOPLE THAT HAVE HAD THIS HAPPEN AND WE ALSO TALKED TO A REPAIR SHOP THAT SAID HE HAD A LOT OF THESE COME INTO HIS SHOP ALSO. WE JUST WANT THIS MADE KNOWN AND IT SHOULD BE A RECALL, BUT ALSO A WAKE UP CALL TO USE BETTER MATERIALS. *TR

BRAKE LINE FAILURE. THIS IS MY VEHICLE'S THIRD BRAKE LINE FAILURE DUE TO RUST. ALL OF MY BRAKE LINES HAVE RUSTED TO THE POINT THAT THE BRAKE LINES ARE NOT SAFE. THE BRAKING SYSTEM IS NOT SAFE. THERE IS NO EXCUSE FOR SUCH POOR MATERIALS. STAINLESS STEEL BRAKE LINES SHOULD HAVE BEEN USED! MY VEHICLE HAS BEEN REGULARLY WASHED DURING WINTER MONTHS OF SALT AND DEBRIS. FUEL LINES ARE NEAR FAILURE AS WELL. TRANSMISSION COOLING LINES ARE RUSTING AND LEAKING. OIL COOLING LINES ARE RUSTING AND SEEPING AS WELL. RUST HAS A MUCH HIGHER TENDENCY WHERE ANY OF THESE LINES ARE HELD IN PLACE BY THE PLASTIC CLIPS. (USUALLY LOCATED ALONG THE FRAME) IN ADDITION, RUST IS FORMING HEAVILY AT TRANSITIONS FOR ALL OF THE ABOVE LINES. FOR EXAMPLE: RUST IS HEAVY WHERE THE FUEL LINES HAVE CRIMPED HOSES ATTACHED. THIS IS A MAJOR SAFETY HAZARD. *TR

I HAD THE TRUCK TOWED TO MY MECHANIC AND HE ADVISED ME THAT ALL THE BRAKE LINES ARE CORRODED. I CONTACTED GM, AND THEY HAD A DEALER LOOK AT THE BRAKE LINES AND CONFIRMED THAT THEY WERE CORRODED. THE CORROSION IS A LATENT DEFECT AND AS I LEARNED FROM YOUR WEBSITE AND OTHER BLOG, GM HAS A MAJOR DEFECT THAT THEY REFUSE TO REMEDY. I STRONGLY BELIEVE THAT SOME ONE MAY GET SERIOUSLY INJURED, BASED ON MY EXPERIENCE. I WAS FORTUNATE... THANK THE LORD!. *TR
