  • Copper Nickle Brake Line

    I have been using this stuff to make lines for my '53 FFPW. Great stuff. No need for a bender. You can form it with your hands. The usual care is needed to avoid kinks, but it doesn't seem to be much of an issue. I got mine at Amazon.

    A friend of mine likes the copper alloy line for his datsun 510's.. i have concerns about fatigue resitance in high vibration applications. Especially in a single line system.
    Make sure your lines are well supported with rubber covered eyelets. Every 20" or so.
    Be safe.

      It feels a little flimsy to me but maybe OK

        Several years ago they came out with the Poly Armour brake lines, most of them are green in color, I have been using them for quite some time. They seem to hold up well and are very easy to bend by hand. I normally pick them up from NAPA.

          I use the Poly Armour lines too and I like them. My brake lines are all armored steel, but I made my vacuum lines out of Poly Armour and they bent up real nice. Easy to get at the local NAPA store.

            I'm using the CuNi lines on mine, in the 1/4" flavor though. Figured a little more diameter but with the same wall thickness, it would become a little more rigid. I don't mind it and actually its easy to work with and even has spoiled me. I flared a 3/16" steel line for a co-workers race car the other day, and did it by hand with a flare tool that I had been using for my 1/4" CuNi before getting my hydraulic flare tool, and man, it made me remember quickly how much harder the steel lines are.

            My truck is going to see a good bit of beach time, and its already heavy salt air where I live, so I am thinking corrosion is going to be a big concern for me vs fatigue. <--- thats me jinxing myself. Callin it here.
