It's intteresting to read everyones ideas.
Goes to show how ideas change thruout the world.
Here in Canada it is illegal to use copper lines (They will not pass a safety inspection that way) I like the idea of copper not rusting
Because any rust and or flaking on our lines will also result in failing a safety inspection.
I wounder if Denmark uses a different type of copper line especially for brake line application? Is it of a harder compound/wall thickness?
When I went to trade school they told us that the copper lines would swell and eventually fail. ( If I'm not mistaken army Jeeps Vehicles used copper right into the late 1970's.) I remember installing some raider units on 6 wheel drive trucks and couldn't believe they had copper lines. Assumed it was a special army issue.
