WHILE PULLING A CAMPER-TRAILER, I APPLIED THE BRAKES AND THE PEDAL WENT COMPLETELY TO THE FLOOR. I WAS ABLE TO STOP UTILIZING THE BRAKES ON THE TRAILER. I WAS ONLY A SHORT DISTANCE FROM HOME AND I WAS ABLE TO GET THE TRAILER BACK, KEEPING THE TRANSMISSION IN 1ST GEAR AND THE TRAILER BRAKES. I TOOK THE TRUCK TO A CHEVY DEALER THAT WAS JUST A VERY SHORT DISTANCE UTILIZING THE GEARS AND THE EMERGENCY BRAKE. UPON INSPECTION, THE DEALER FOUND AT LEAST TWO LOCATIONS WHERE THE BRAKE LINE HAD RUSTED THROUGH. HE RECOMMENDED TO REPLACE ALL BRAKE LINES WITH A LINE THAT WAS CORROSION RESISTANT. THE REPAIR WAS JUST UNDER $2000. I HAVE NOT CONTACTED GMC SINCE THE TRUCK HAS 74,000 MILES AND IS OUT OF ALL…

I WAS TRAVELING ON THE INTERSTATE TOWING A 5TH WHEEL TRAILER AND TRAFFIC CAME TO AN ABRUPT STOP. I APPLIED MY BRAKES AND HAD BRAKES THAN THE PEDAL WENT TO THE FLOOR AND I LOST BRAKING POWER. I LET OFF THE BRAKES AND REAPPLIED THE BRAKES AND THE PEDAL WENT TO THE FLOOR WITH LOW BREAKING AFFECT. I PULLED THE TRUCK OVER AND FOUND BRAKE FLUID COMING OUT FROM ABOVE THE GAS TANK. I CAREFULLY TOOK THE TRUCK OFF AT THE NEXT EXIT USING MY TRAILER BRAKES TO STOP THE VEHICLE. I TOOK THE TRUCK TO THE FIRST SERVICE STATION THAT I SAW AND HAD THEM LOOK AT IT. THEY FOUND THAT THE REAR BRAKE LINE HAD CORRODED AT A CLIP ABOVE THE FRAME RAIL ABOVE THE GAS TANK AND ADVISED ME THAT THEY WOULD HAVE TO REPLACE…

THIS PAST WEEK, AS I WAS DRIVING TO GET GAS FOR OUR CAMPING TRIP, THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR WITH NO WARNING. I WAS ABLE TO GET THE DUALLY SLOWED DOWN WITHOUT INCIDENT, BUT WAS IT EVER CLOSE. AFTER GETTING THE TRUCK BACK TO MY HOUSE, I BEGAN INVESTIGATING THE ISSUE AS I SAW NO LEAK AND THE RESERVOIR WAS NEAR FULL. I SAW ONLINE THAT THIS SEEMS TO BE A GM ISSUE WITH A FEW YEARS OF TRUCKS IN MY AGE BRACKET. I CLIMBED UP UNDER THE TRUCK AND FOUND THE LINES TO BE SHOT. NOT ONE WITH A RUST HOLE, BUT ALL OF THEM CORRODED FROM ONE END TO THE OTHER. I KNOW THE TRUCK IS 8 YEARS OLD, BUT IT SITS MOST THE TIME AND ALMOST ALWAYS THROUGH THE WINTER. I HAVE ONLY HAD ONE OTHER CAR IN 30…

BRAKES FAILED DUE TO A SUDDEN BRAKE LINE FAILURE. THERE HAD BEEN NO PRIOR FLUID LEAKS. THE REAR METAL BRAKE LINE UNDER THE BED RUSTED AT A CLAMP IN FRONT OF THE FUEL TANK. AS I HAVE LOOKED FURTHER INTO THIS I HAVE SEVERAL FRIENDS THAT HAVE HAD THIS PROBLEM AND SEVERAL SHOPS SAID THAT THEY SAW THIS OFTEN WITH THESE VEHICLES ALL FAILING IN THE SAME AREA. *TR

I PICKED MY STEPDAUGHTER AT SCHOOL AND AT THE STOPLIGHT TO LEAVE THE SCHOOL THERE WERE NO BRAKES. I USED THE CURB TO SLOW THE TRUCK ENOUGH TO THE LIGHTS TO CHANGE. IT WAS NOT A BUSY TIME AND STUDENTS WERE NOT PRESENT OTHERWISE THIS WOULD HAVE BEEN A DISASTER. I DROVE THE TRUCK HOME WITH FLASHERS VERY SLOWLY HOME ON A BACK ROAD DOWNSHIFTING AND RELYING IN THE ALLISON TRANSMISSION. WHEN I REACHED HOME THE LIGHT CAME ON TO SERVICE BRAKES. THAT WAS OBVIOUS ALREADY. THIS IS A 1 TON DUALLY THAT USUALLY HAULS SKID LOADS, PAVING BRICKS, ETC. I COULD NOT IMAGINE WHAT WOULD HAVE HAPPENED IF THE BRAKE LINES BLEW DURING THIS TIME. THERE IS A SMALL RUSTED PIN SIZED WHOLE IN THE FRONT BRAKE LINE THAT…

APPROACHING A STOP. WHEN THE BRAKES WERE APPLIED, THE BRAKE PEDAL DROPPED ALMOST COMPLETELY TO THE FLOOR AND STOPPING WAS EXTREMELY DIFFICULT. DISCOVERED THAT THE BRAKE LINES WHICH RUN ALONG THE FRAME BEHIND THE DRIVER SIDE FRONT WHEEL HAD CORRODED TO THE POINT WHERE ONE OF THE LINES FAILED AND BLEW OPEN. THE LINES ARE CLAMPED AGAINST THE FRAME IN THIS LOCATION, AND ALL THE 4 LINES AT THE BRACKET APPEAR EXTREMELY CORRODED. *TR
