Brake Light Problem

[CougKid3030]

My brake light just decided to stay on one day.
I've got a 1986 Pick-Up, 4x4, and after one day of four wheeling the light just decided not to go away. I know the brake is A) Disengaged, and B) Still works, but the light is just ... always on. No charge light however, so Its different then the other post I read on here. I did notice that sometimes it does shut off... mostly when flying over railroad tracks. Think its possible just a loose wire bouncing around in the dash? Or could it be a precursor to an E-Brake problem?

Is the brake fluid reservoir full? What condition are your brake pads and shoes?

... they probably are pretty shoddy actually. Bigger tires/water every now and then getting up and over the wheels... I'll look in the morning. Thanks for the direction.

When mine needed replacing, the first sign was the light coming on for a second when I would stop the vehicle and eventually it was on all the time
