Chris,
Copper brake lines are certainly NOT a good idea, but the problems
are more long term than short term. The kind of vibration which brake lines
get exposed to will cause copper to work harden, making it hard and brittle,
and hence likely to break. This is not an overnight phenomenon, but I no
longer fit them to my vehicles - I did use them before I knew better!
CuNiFer pipes are a much safer idea, and actually look much more appropriate
where they are visible, being a subdued metallic brown in colour.
Here in the UK, Copper pipes are supposedly an MOT failure point,
though I have never known a vehicle to actually fail for this. Also, several
companies still produce and market Copper pipe sets here (I would be
interested to hear from anyone who has access to an MOT testers handbook and
can tell me what the rules really are). Make sure that whatever you fit is
actually legal where you will be using the car,
Cheers,
Bill.
