It has probably been mentioned, but when talking about Snap-on tools, keep this in mind. They can be brutally expensive but don't have to be. Many of my students buy Snap-On tools at pawn shops, on E-bay, Facebook Marketplace, and Craigslist. Typically, they are paying 25-35 cents on the dollar for high quality tools which puts them just slightly higher than the new Chinese junk you can buy at retail.

A lot of times, it is not that the threads are rusted but that the nut is rusted to the line itself. Spray the PB or Kroil in between the line and the nut, as well as into the threads.

Same deal here. The flare nut wrench should not grow in diameter as you apply force. The vice grip pliers really help with keeping the flare nut wrench securely around the nut. Last thing you want to do is bugger up that brake line part.

I've had the same thing happen to me, wound up buying new lines. The vise grips may be the only option left to get it loose. From my experience, when it's that stuck, the flare nut and line are often corroded together. So if you do get the nut loose, it will twist the line too.
