try replacing the brake light switch; it is located under the dash directly behind where the brake pedal is. it should actually have a small button that is released when the pedal is depressed.

There is a plunger that moves in and out acting as a switch when the brake pedal is depressed. It is this switch which possibly may be the culprit.
