IN THE LAST WEEK OF OCTOBER, 2009, MY FATHER AND I WERE PULLING A BUMPER HITCH CAMPING TRAILER WHEN THE TRUCK BRAKES FAILED. WE WERE ABLE TO LIMP THE REST OF THE WAY HOME BY USING THE EMERGENCY BRAKE AND THE ELECTRIC ASSIST BRAKES ON THE CAMPER. WHEN WE HAD THE BRAKES INSPECTED, WE WERE TOLD THAT THE METAL BRAKE LINES ON THE DRIVERS SIDE OF THE VEHICLE HAD CORRODED INSIDE THE FRAME, NEXT TO THE GAS TANK. THE BRAKE LINE WAS REPLACED AND NO FURTHER INCIDENT HAS ARISEN. *TR

TL*THE CONTACT OWNS A 2000 GMC SIERRA 2500. THE CONTACT STATED THAT THE VEHICLE HAS A LEAK IN THE BRAKE LINE THAT FLOWS BELOW THE FRAMEWORK. THIS FAILURE CAUSES THE VEHICLE TO LOSE BRAKING ABILITY. WHILE DRIVING 35 MPH IN DRY CONDITIONS, THE CONTACT HAD TO DEPRESS THE BRAKE PEDAL TO THE FLOORBOARD IN ORDER TO STOP THE VEHICLE. THE CONTACT BROUGHT THE VEHICLE TO THE DEALER WHO FOUND RECALL # 00V345000 FOR THE SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS. THE CONTACT'S VEHICLE IS EXCLUDED FROM THE RECALL. HE ADDS BRAKE FLUID EVERYDAY TO ENSURE THE VEHICLE STOPS PROPERLY. THE CURRENT AND FAILURE MILEAGES WERE 100,000.

PERIODICALLY, WITHOUT WARNING, THE BRAKES MALFUNCTION ON MY 2000 GMC SIERRA PICKUP. AFTER THE BRAKES ARE APPLIED, THE VEHICLE BEGINS SLOWING, THEN YOU CAN FEEL A SENSATION OF THE BRAKING ACTION RELEASING, NO MATER HOW HARD THE BRAKE PEDAL IS PRESSED. THE SENSATION IS LIKE SOME OF THE BRAKES HAVE LET GO AND ARE NOT LONGER BEING APPLIED. I HAVE HAD NO ACCIDENTS BUT THERE HAVE BEEN SEVERAL TENSE CLOSE SITUATIONS AT TEE INTERSECTION, WHICH COULD HAVE BEEN VERY BAD. THIS HAS OCCURRED SINCE THE VEHICLE WAS NEW. WE HAVE HAD IT IN FOR CORRECTION SEVERAL TIMES, BUT IT HAS NOT BEEN CORRECTED. IT SEEMS TO BE A PROBLEM IN THE ABS SYSTEM. GMC AND THEIR REPRESENTATIVES WERE UNABLE TO FIND THE PROBLEM WHILE THE AGE AND MILEAGE OF THE VEHICLE WERE WITHIN THE WARRANTY LIMITS AND NOW DO NOT WANT TO PAY FOR ANY DIAGNOSIS OF THE PROBLEM AND POSSIBLY ANY CORRECTION. THE LAST INCIDENT OCCURRED ON FEBRUARY 17, 2007.*JB
