When removing flare nuts on the brake lines of older cars, I have had same problem. The flare wrenches were sometimes not a good fit. I sometimes used a
special vice-grip that is designed to grip hex heads along with a piece of tube to increase leverage. Whatever, you need something that fits the head and won't slip and round it. I have also just cut the tubing and used a ring spanner (box end wrench). But only when I could replace the tube easily with a short length.
To get the nut to release, I have used one of those small butane torches. Just heat the nut, try to turn. Repeat until it comes loose. Brake fluid can take a high temperature, so don't worry about that. But keep flame away from rubber parts.
