removing brake line fittings

IMO If they are that rusty and crusty it would be wise to just replace the line.

Advance auto/most auto stores carry brake line in many lengths and you can just bend it yourself. The lines are probably crusty on the inside from being there for many years.

If your flare nut wrench wont do it then you will have to go to the vise grips.

Better safe with good brakes then sorry with a smashed up car. :burnout:
