That was last week; this weekend I get to try and remove frozen bleeder
screws from my disc brake calipers; oh lucky me!

Got any R-12? (Totally non PC, and proud of it.) Freeze the screw,
heat the caliper body, and turn with a brake line wrench or 6-pt
socket.

Yeah, but at the price of R-12 nowadays you don't want to waste a
drop of it - and the price is only going to go in ^one^ ^direction^.
Use something cheaper, more benign and easier to get like CO2, R-22 or
R-134 for making with the freezing.

Try rocking or tapping the screw in both directions to break it
loose using a box wrench and a small hammer - mass quantities of force
applied on that little bitty bleeder screw are going to have bad
results, persuasion is called for.
