2000 Ford Windstar Q&A
2000 Ford Windstar Question: Why does my right brake light stay on sometimes and drain the battery?
What type of vehicle are we dealing with? You could have one tail light out and a stuck brake light switch... if you have to refill the fluid constantly, you have a leak somewhere. The level will go down over time with brake pad wear but should never become so low that it would turn the inside warning light on, unless there was exreme wear on the pads. How often and how much are you adding brake fluid? - fenskiauto
