brake light switch
I drive with hand controls. Over the years in numerous cars I have owned the ones I had problems with are the brake systems like the stock turbo regal power master. I always had to remember to pull the hand controls back or they would weigh down on the switch causing the brake lights to stay on killing the battery. When I converted a few turbo regals to vacuum I never had that problem again. If my memory serves me correctly the switch is threaded plastic that can strip out. You need to observe the part and if that is the case then replace it. Don't forget to adjust it correctly.
