Because in general, copper is more prone to cracking, as it work hardens
when it is bent or compressed- thus copper sealing washers and gaskets
need to be re-anealed when reusing them. It's also more ductile, so can't
stand up to as high a pressure rating as steel. (Brake line pressures are
in the 1000-2000+ psi range). So, here anyhow, there are no approved
copper brake lines (DOT, Department of Transportation) in the U.S.
A while back, someone roumered that the "copper" lines sold in England
were actaully copper clad steel- could someone who has access to them
either verify or dispell this please? They would be made out of a
different alloy than plumbing copper.
