I WAS PARKED IN A FRIENDS DRIVEWAY AND WAS ABOUT TO LEAVE WHEN I RELEASED THE PARKING BRAKE STEPPED ON THE BRAKE PEDAL AND PUT MY 2002 GMC 2500HD TRUCK INTO GEAR. I STARTED DRIVING DOWN THE STREET AND APPROACHED A STOP SIGN, WHEN I APPLIED THE BRAKES THE PEDAL WENT STRAIGHT TO THE FLOOR. I PULLED OFF TO THE SIDE OF THE ROAD AND OPENED THE HOOD WHEN I NOTICED BRAKE FLUID ALL OVER THE FRAME IN THE ENGINE COMPARTMENT. UPON FURTHER INVESTIGATION I FOUND ALL THE BRAKE LINES TO BE SEVERELY RUSTED AND AT LEAST ONE OF THEM RUPTURED. I WAS DRIVING WITH MY 9 MONTH OLD SON AT THE TIME OF THE INCIDENT AND THANK GOD NOBODY WAS COMING THE OTHER WAY DOWN THE ROAD. I HAD THE TRUCK TOWED TO MY HOME WHERE IT SITS AWAITING A TOTAL BRAKE LINE REPLACEMENT. THE UNDERNEATH OF THE TRUCK IS SO SEVERELY RUSTED I THINK GMC IS LIABLE AND SHOULD ISSUE A RECALL TO CORRECT THE PROBLEM. *TR
