Frozen Parking Brake

It got coooold here last night. Not being from the frozen north, I didn't know that you're not supposed to apply the parking brake when it gets cold; in fact I didn't even know it was supposed to get that cold.

So what do I do to un-freeze it? I've idled for about 30 minutes hoping the exhaust would warm it up, but no joy. It doesn't get direct sunlight down in my building's garage, so it's unlikely that the sun will warm it enough to unfreeze it.

Suggestions more than welcome at niel@bornstein.atlanta.ga.us.
