When we encounter this problem, we use DOT approved nickel copper replacement lines, which have two major advantages: Then are malleable enough to be formed in place, and they will never rust.

I would absolutely second the use of nickel copper lines. It actually makes me cross that manufacturers put steel lines in. Even as a “retail” customer the cost of nickel copper is so very little more and the adverse impact of using steel on longevity and maintenance costs is very great.

Even more peculiar, Asian manufacturer's use mild steel brake hard lines that are coated with a rubber/plastic covering that totally eliminates corrosion. We regularly see a customer's 27-year-old daily driver Nissan that has been exposed to winter road salt since day one, and the original factory mild steel hard lines are in perfect condition. Just a few more cents can make all the difference.....
