99 Escort problems?

Its not a park brake light, its a brake warning indicator light. Its telling you there is a problem with the brake system, most likely low brake pads, low brake shoes, or a leak in the system causing the fluid level to drop. I'm suggesting take it to a brake shop and have a brake inspection done. And you will have to go from there. I work in a brake shop and i see this all the time, even if the brakes arn't making noise and there is no pulsation. just do not top off your brake fluid up until you have a professional Technician take a look at them.
