Any tricks to removing a stuck/stubborn/rusted-in place bleeder?

I wish it was that easy! The front calipers are Sterling brand, and I've had a helluva time just finding rebuild kits for them ("just in case", you know?), let alone new calipers.

Sure wish I didn't run into all of this "domestic content" BS every time I turn around with his car.
Oh, didn't know about the Sterling brand, hope its an easier time getting the bleader out, sending some Hoppy positive vibes on heating and wax deal.
