    Hiya folks.

    1953 Chevrolet 3100 series(half ton) pickup

    I am trying to replace all of the brake lines as I had a rupture last year, I have all of the lines removed, finally.
    I had to take the MC off the truck in order to get this brake line loose.
    I have questions about the line that goes into the back of the brake master cylinder, it has a thread on it, then it passes through the brass piece on there.
    Can I buy a new brake line with this thread on it? I've never seen a brake line quite like this before, so I'm guessing the parts store people will be equally confused.
    Any help on terminology or a parts source is appreciated, thank you.

    Next time cut the lines close to the brass fitting and use an small impact (3/8) and a 6 point socket to zip the fittings right out. The brass fitting has copper washers under the hollow bolt and between brass fitting and mc that must be replaced. The three lines on the brass fitting have this layout: one line to the left front, one to the right front, and one to the rubber hose on the rear end. I WOULD NOT use original steel lines as they are hard to make tight bends and will corrode again especially where salt is used or in coastal areas. Use Cunifer, copper-nickel-steel, line as it is very easy to bend by hand and does not corrode. If you buy the recommended line just ask for copper/nickel and not Cunifer as you pay a bunch more for the name.

    I put the bolt in a vice and took a pair of vice grips to the corroded brake line side, where the nut was rounded off... after a few attempts with the old metal on the brake line flaking off, finally got down to some good metal with a grip and the brake line nut broke loose. Then I was able to take it apart and clean it up.

    Thanks for the tips folks.
