connects the brake pedal to its bearing block could come loose. If the retaining washer were to come loose, over time it could detach from the bolt, and in the worst case and with ongoing use of the brake pedal, the bolt might separate from the bearing block on one side. If this were to occur, the brake lamp switch could become continuously activated even when the brake pedal is not pressed.
