Why do car makers use steel brake lines over copper or stainless?
Had an MOT fail on tin top yesterday with coroded front brake line. Its only a 51 plate too, partly my fault for the fail for not checking, but
still considered it fairly new so didn't bother checking them in detail.
Copper too soft and stainless too brittle/expensive?
copper too expensive I suspect (kunifer alloy doesn't work harden like the pure copper ones can)
stainless... don't know, might fail in a bad way when it does go?
Don't some manufacturers use plastic coated steel these days?
Paying dealer prices to get them fixed on a 51 doesn't sound like much fun.
Steel is cheaper, is easier to be fabricated on a CNC former (less springback)

I used to have a Citroen BX (no, don't laugh) - every time I took it for a service the garage used to clean the miles of hydraulic pipes and spray them with underseal. Although this obviously got added to the bill I was very grateful, as getting Citroen hydraulics fixed is horribly expensive! I never had an MOT failure due to corroded pipes...
