This is an interesting new one on me. I thought brake lines absolutely needed to be made out of steel, but apparently a copper-nickel alloy is significantly superior and Volvo + others have been using it exclusively since the mid-1970s: http://www.cunifer.com (scroll down to the bottom of the page for links to detailed papers) |

I wonder what the cost difference is. I'm strongly debating on replacing all my hard lines when I R&R the brakes on my Duster, and this sounds like a good idea. On the subject of hard brake lines, What's the deal with the "coil" of hard lines that I usually see fairly close to the master cylinder? I see alot of people purposefully do that in their custom line installations and I've always wondered what the reasoning is. |

Isn't the coil to protect rubbing?

Im too lazy to cut the tube to length, and the spiral solution looks fine. It also provides a good bit of springy slack to get the fitting started. |

As I understand it, the loops between master cylinder and metering block are to allow that line to move/flex with normal car vibration, without fatiguing the metal over time. |

Also, I usually see it with body on frame construction where the master is connected to the body and the brake lines to the frame.... Allows some movement between the two.
