'95 Rodeo ... my "Rear ABS" and "Brake" (seen only when handbrake is used) lights on the dash come on sometimes when I use the brake while doing normal driving. Flickers on and then off right away. It's been like this for at least the last year but rare. Yesterday it came on and stayed on... until I turned the car off after my trip... next time I turned it on... it's not there anymore.

Is this a sign of bigger problems or just a faulty signal being sent ? There's no "check engine" or anything... haven't actually tested my ABS by jamming the brakes and don't want to unless it's a last resort.
