Before I Strip the Brake Line Fitting all to H$%$?

Cut the rubber brake hose off clean with the fitting.

Next take a terry cloth small wet towel piece, and wrap the brake line and keep it cool up to your fitting wrench.

Then heat the brake hose fitting cherry red. As soon as it's red, wrench them apart.

Like RRR says a pre-soak with PB Blaster does wonders.
