WHILE DRIVING VARIOUS SPEEDS AND ATTEMPTING TO SLOW DOWN BY DEPRESSING THE BRAKE PEDAL, THE BRAKE PEDAL TRAVELED TO THE FLOOR AND MADE IT VERY HARD TO STOP.

ALL MY BRAKE LINES ARE CORRODED/RUSTING OUT. ONE LINE ALREADY HAD TO BE REPLACED. VERY DANGEROUS. ALL MY FUEL INES ARE STARTING TO CORRODE AND APPEAR TO REQUIRE REPLACEMENT SOON.

GOT OUT OF TRUCK AND FOUND LARGE SPOT UNDER MY TRUCK,BRAKE FLUID. HAD IT TOWED TO BRAKE SHOP AND MECHANIC INFORMED ME MY BRAKE LINES WERE RUSTING THOUGH AND NEEDED TO REPLACE ALL BRAKE LINES. ALSO TOLD ME HE HAS SEEN THIS WITH 3 OR 4 OTHER CHEVY TRUCKS LATELY. FOUND OTHER COMPLAINTS AFTER TELLING MY STORY. HEARD THIS IS A KNOWN PROBLEM WITH THESE TRUCKS..I BOUGHT THIS TRUCK NEW & HAVE HAD IT RUST PROOFED 12 TIMES. THANK YOU

WHILE BACKING OUT OF MY DRIVEWAY I ATTEMPTED TO STOP DUE TO TRAFFIC TRAVELING ALONG THE ROUTE I WAS ENTERING. WHEN I APPLIED THE BRAKE THE PEDDLE WENT COMPLETELY TO THE FLOOR. LUCKILY I WAS ABLE TO STOP WITH THE EMERGENCY BRAKE IN TIME TO AVOID AN ACCIDENT WITH A TRASH TRUCK THAT WAS TRAVELING ALONG THAT ROUTE. USING THE EMERGENCY BRAKE I WAS ABLE TO PULL THE VEHICLE BACK INTO MY DRIVEWAY SAFELY AND FOUND THAT THE BRAKE LINE WAS CORRODED AND WAS LEAKING JUST UNDER THE DRIVERS SIDE DOOR. MY VEHICLE IS WELL MAINTAIN AND I AM OFTEN COMPLEMENTED FOR THE CARE I TAKE OF BOTH IT'S APPEARANCE AND MAINTENANCE. THE IS NO OTHER AREA OF THIS VEHICLE THAT IS RUSTED AND THE UNDERNEATH OF THIS VEHICLE IS IN VERY GOOD SHAPE. I AM THE ORIGINAL OWNER OF THIS VEHICLE AND IT HAS NOT BEEN SUBJECT TO ANY TYPE OF EXCESS WEATHER CONDITIONS. THERE IS NO REASON THESE LINES SHOULD HAVE FAILED LIKE THIS. I HAVE BEEN AN ASE CERTIFIED AUTO TECH FOR BRAKES AND CAN TELL YOU THAT IS IS NOT COMMON TO CHECK THE LINES OVER THE TOP OF THE FRAME DURING ROUTINE BRAKE INSPECTIONS AND MAINTENANCE, ONLY TO CHECK FOR SIGNS OF LEAKS IN NORMAL LINE LOCATIONS AND SOFT LINES, CALIPERS AND OTHER HARDWARE RELATED TO THE WHEEL AREA.

I OWN A 2002 CHEVROLET SILVERADO LS HD2500, ORIGINAL OWNER PURCHASED IN JUNE OF 2002, CURRENTLY HAVE 71,000 MILE, BEAUTIFUL TRUCK VERY WELL MAINTAINED. THIS IS MY SECOND COMPLAINT BEING FILED ON THIS VEHICLE CONCERNING MY BRAKES. MY FIRST COMPLAINT WAS FILED IN MARCH OF 2014, WHEN MY BRAKE LINES RUSTED THROUGH AND I WAS LEFT WITH NO BRAKES. AFTER SEARCHING ON-LINE, I FOUND THAT THIS IS A KNOWN PROBLEM FOR THESE VEHICLES AND THERE IS A RECALL ON SOME OF THESE VEHICLES, BUT NOT ALL OF THEM. MY COMPLAINT TODAY ALSO HAS TO DO WITH MY BRAKES. ONCE AGAIN, I FOUND THAT SOME OF THE VEHICLES HAVE A RECALL, BUT NOT ALL OF THEM . THE ANTI-LOCK BRAKE SYSTEM WOULD ACTIVATE, CAUSING MY BRAKES TO NOT WORK. IF I WANTED TO STOP, I COULDN'T SLOW DOWN TO STOP, I WOULD HAVE TO BRAKE HARD TO STOP MY VEHICLE, IF I TRIED TO SLOW DOWN TO STOP, MY ANTI-LOCK BRAKE SYSTEM WOULD ACTIVATE, CAUSING MY BRAKES TO NOT WORK. I DID CONTACT GM, AND WAS TOLD THAT THERE WAS NOTHING THEY COULD DO TO HELP RESOLVE THIS PROBLEM WITH MY VEHICLE BECAUSE MINE WAS NOT INCLUDED IN THE RECALL, EVEN THOUGH SOME OF MY YEAR, MAKE AND MODEL HAD A RECALL NOTICE. THEY ARE WELL AWARE OF THIS PROBLEM, BECAUSE THEY DO HAVE A BULLETIN OUT INFORMING THE DEALER HOW TO RESOLVE THIS PROBLEM. ONCE AGAIN, THIS IS THE BRAKE SYSTEM, VERY DANGEROUS, COULD BE FATAL. NOT SURE WHY THIS ISN'T A PRIORITY TO RESOLVE.
