Another thing to check - Make sure the upper floorboard is not restricting the brake pedal from returning to its topmost position. That in effect is like lightly depressing the brake pedal and may be why the brake light is constantly on. To check, simply remove the upper floorboard and see if the pedal continues moving to its top position (towards the rear of the car). If so, the problem can be corrected by adjusting the short brake rod from the equalizer to the brake pedal, or by creating a tunnel cutout in the floorboard itself for the brake pedal arm to settle. The pedal itself may be bent and hitting the floorboard too soon. But first find out if the floorboard is stopping the brake pedal from returning to its topmost position, and then go from there. Also check the position of the stoplight switch afterwards, as described in my previous posting.
