Copper nickle iron (CuNiFe) brake line is absolutely lovely.

This material is a big improvement over steel lines. I don’t think I’m ever going back.

I bought a 25′ reel of 3/16″ from an Amazon seller, along with a ten-pack of 10mm flare nut fittings. I know, I know, should have bought 11mm fitting instead. No big deal either way, it’s easy enough to swap them out. Once you bend a line for this new material you will never go back to steel. I suspect these lines will be far more resistant to corrosion, although that remains to be seen.

On to the pictures!
