Well, whaddayaknow! Yesterday, it was warmer out (50F? in Dec, in PA??) and the light didn't come on. So I stopped and wanted to look to see something under the hood (clip broke on the hood prop) and I took another look at the brake fluid res...sure enough, it looked like it was 'tween Min-Max but really it was just at Min...so I'm gonna top it off to Max and see what happens. Atleast this means my brakes are wearing...
