Normally if I need to replace fixed brake lines I get one made up (in copper) at the local motor factors. Last time I looked though I saw cupro-nickel pipe for the same purpose. What's the difference? I thought the addition of nickel would be to prevent corrosion, but copper doesn't, so I'm not sure I see the reason for a copper-nickel mix. But it is slightly more expensive, so it must be better. Question is, why?

Thanks in advance for the answer.

Pete,

Pretty sure this is because copper suffers badly from work hardening, and is therefore prone to fracturing. Nikel increases the ductility and avoids this problem, and the brake lines will last more or less for ever.

Is it illogical? It must be Citroen....

The 'copper' pipes you are buying are almost certainly not pure copper anyway, I think they are all an alloy including nickel.
