I would use a cheap tube bender. Many U.S. cars have steel wire wrap over brakes tubes from where it passes under the frame rail to the outer bracket. Many think it is for protection from rocks, but I read it was so the factory workers could quickly bend it by hand without kinking. Makes sense, but I expect much carpal tunnel syndrome from doing that all day. Seems like they would have had a machine for that, but the wrap would still serve to avoid kinks, plus add protection.
