THE 97 F-150 HAD BEEN PARKED OUTSIDE NOT STARTED FOR 2 DAYS. SUNDAY MORNING WE WENT TO GO TO THE LAKE AND THE TRUCK STARTED BUT WOULD NOT GO OUT OF PARK,AN ISSUE I HAVE HAD BEFORE,BUT THIS TIME THE ABS LIGHT WAS FLASHING. I HAVE BEEN IN THE AUTOMOTIVE REPAIR BUSINESS FOR 15 YEARS, SO I HAD A GOOD IDEA WERE TO START LOOKING. THE FIRST PLACE I LOOKED WAS THE BRAKE SAFETY SWITCH LOCATED ON THE TOP OF THE BRAKE PEDAL ITSEL. EVERY THING CHECKED OUT FINE. THAT IS WERE I HAVE HAD THE PROBLEM BEFORE SO I THOUGHT IT WAS ANOTHER BROKEN WIRE BUT THAT WAS NOT THE CASE. SO I DECIDED TO CHECK BRAKE FLUID LEVEL,AND NOTICED THAT THE ELECTRICAL PLUG LOCATED AT THE FRONT OF THE MASTER BRAKE CYLINDER HAD CAUGHT FIRE AND MELTED THE ENTIRE PLASTIC PLUG AND WIRES. NOW I DON'T KNOW WHEN THIS HAPPENED BUT I FEEL VERY LUCKY IT WENT OUT BY ITSELF!I LIVE IN THE COLORADO MOUNTAINS AND COULD NOT IMAGINE THE DAMAGE IT COULD OF CAUSED IF IT WOULD HAVE GOTTEN OUT OF CONTROL, AS IT WAS PARKED BY TREES ,SHED, JET SKIS,ETC. AT THIS TIME I AM GOING TO TRY TO REPLACE THE PLUG AND OR WIRING HARNESS AND THE ELECTRICAL COMPONENT ON FRONT OF MASTER CYLINDER THAT I BELIEVE WAS THE CAUSE OF THE SMALL FIRE. I WILL CALL FORD DEALER SHIP IN MORNING TO SEE IF THEY HAVE ANY INFO ON PROBLEM. I HAVE ALL OLD PARTS AND HAVE DOCUMENTED THE ISSUE WITH PICTURES. I HAVE ALSO NOTICED THAT THE CRUISE CONTROL SWITCH BOX IS LOCATED ABOUT 3 INCHES FROM THE ELECTRICAL BRAKE SWITCH THAT CAUGHT FIRE. I DO KNOW ABOUT THE CRUISE CONTROL
