Brake lites always on. Everything else seems ok. U can turnit on and drive it. Ucan turn head lights, tail lites on and off. Brake pedal wrks. When I park it I unplug battery so lites wont drain it

under the dash follow the brake pedal upwards until you reach the brake lite switch. there is a plastic pad that actually contacts the switch, the pad is shattered and probably no longer in place. you can either replace the pad (see online) or Krazy glue a coin where the pad used to be.
