THE SUBJECT VEHICLE HAD RECENTLY BEEN PARKED AFTER TOWING A 29 FOOT LONG TRAVEL TRAILER. IT HAD SAT FOR APPROXIMATELY TWO WEEKS SINCE WE LAST USED IT. DURING THE 2011 30 OCTOBER SNOW STORM IN PA, I WENT TO PICK IT UP TO USE IT. I STARTED DOWN THE DRIVEWAY AND WENT TO APPLY THE BRAKES AND THE BRAKE PEDAL TRAVELED TO THE FLOOR. ALL OF THE ANTILOCK AND BRAKE WARNING LIGHTS APPEARED ON THE DASH. I WAS ABLE TO STOP THE VEHICLE AND BACK IT BACK THE DRIVEWAY AND PARK IT. WE LATER CALLED AAA AND HAD IT TOWED TO A LOCAL CHEVY DEALER. THEY DIAGNOSED THE PROBLEM AND LET US KNOW THAT THEY HAD FOUND A BRAKE LINE THAT BURST DUE TO CORROSION. THIS BRAKE LINE IS ALMOST DIRECTLY UNDER THE POWER BRAKE BOOSTER ASSEMBLY AND IS SOMEWHAT HIDDEN FROM VIEW. IT LIES ATOP THE FRAME IN THIS AREA AND ACCORDING TO THE DEALER HAD CORRODED. ACCORDING TO THE DEALER THEY HAD TO FABRICATE A REPLACEMENT BRAKE LINE AND WERE ABLE TO REPLACE IT. THEY FURTHER INDICATED THEY LOOKED AT THE OTHER BRAKE LINES AND DID NOT SEE ANY FURTHER INDICATION OF CORROSION. I HAVE DRIVEN THE GMC FOR ABOUT TEN MILES SINCE THE REPAIR AND THE BRAKES APPEAR TO BE BACK TO NORMAL. LET ME ADD THIS, I HAVE OWNED 15 DIFFERENT VEHICLES IN MY LIFE AND NOT ONE HAS HAD TO HAVE A STEEL BRAKE LINE REPLACED. THIS IS THE FIRST. JUST LIKE THE OTHER GM OWNERS, WHEN THESE LINES FAIL THE BRAKING ABILITY TO STOP THIS TWO TON VEHICLE IS ALMOST NON-EXISTENT I AM VERY THANKFUL THIS LINE DID NOT FAIL WHILE TOWING THE 29 FOOT TRAVEL TRAILER. *KB
