WHILE EXITING THE INTERSTATE RAMP WHERE I LIVE (I-64/NITRO, WV) I HEARD A "POP" SOUND, THEN NOTICED AN ORANGE FLAME COMING FROM UNDER THE HOOD, AND OUT OF THE DRIVER'S SIDE FENDER. AT THIS POINT, I BRAKED TO PULL OFF ONTO THE SHOULDER, BUT LOST ALL BRAKES. (BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR) NO CARS WERE IN FRONT OF ME, AND I WAS ABLE TO ROLL INTO AN INTERSECTION WHERE A TRUCK DRIVER ATTEMPTED TO PUT OUT THE FIRE WITH AN EXTINGUISHER TO NO AVAIL. THE FIRE DEPARTMENT PUT OUT THE FIRE, BUT THE CAR IS A TOTAL LOSS. THANK GOD MY CHILDREN WERE NOT IN THE CAR! *TR
