emergency brake light

Push the handle down. If that makes the light go off, suspect sticking rear parking brake cables. Ford wrote the book on this problem. On most cars you must either use the parking brake every day to keep them working or you must never use them. On fords, especially the rear-whee-drive models, even when you use them all the time the cables still rust up. If the handle is already all the way down, suspect something happened to the switch. Also check the fluid level in the master cylinder reservoir but that would be quite the coincidence for that to trip the light at exactly the same time. If the fluid is low, don't fill it. Just add enough to make the light go off.
