Master cylinder replacement woes

I'll probably get beat up for this, but I don't know that you need the wire over-wrap. I don't see it on new cars. Most people assume it was there to help protect the brake lines from abrasion. Sounds reasonable. But then maybe it was there so the guys at the factory could bend the lines around the frame with their bare hands without kinking the tube, kind of like the spring bending tools. Maybe an old factory worker will explain. Anyway, sounds like you want to keep it to look correct.
