1962 C1 - My parking brake warning light won't go out, even with the parking brake handle pushed all the way in. I just noticed that the parking brake handle will rotate completely, too. I have a new switch in my "stash", but wondered if there's something else I'm missing, before I start tearing things apart. The parking brake is definitely"off" when I push the handle all the way in, but the %$##&^%$ light stays on! What say, folks??
