Non nova, but my my 1990 chevy truck seems to be misplacing some brake fluid. I have to fill it every 50 miles or so. I have pulled all the wheels and ran down all of the lines and cannot find where it is going. This was an all of the sudden problem. I drove it for a few months then all of the sudden started using brake fluid like mad. I can't find it anywhere. Maybe somebody is stealing it. Or maybe not. Any ideas?
