Ok now this is going to sound off base, but it happened to me. My brake light came on AND my charge light at the same time. Turns out the brushes in my altenator where worn down to nubs. So my question is, does the charge light work when you first turn on the key? Is your voltage meter reading about 14-15 volts when the engine is running? Like I said, this sounds way off base, but if your altenator is not charging well, then it WILL trigger the brake light to come on as well. I purchased just the brushes for less than 5 bucks and installed them in less than a half hour. Took care of both of my lights coming on.
