    OK....let\'s have a fireside chat about brake line fittings....

    OK...

    I know that the caliper side of the front is a 10mm bango bolt. what is the fitting that attaches to the hardline?

    I also need to know both ends of the rear brake lines. IIRC, it is a 1/4" line (???)

    If anyone has any help on this it would be really helpful. I might have a line on kustom brake lines for cheap if i can get this info in. /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/1zhelp.gif

    Specs on my rig: 1977 K5 D60 front, 14BFF rear, 1/2 ton brake system w/ stock rubber lines.

    thanks in advance!! /forums/images/graemlins/thumb.gif

    On almost every brake application the hard line is 3/16" with a 3/8" fitting, there are some hard lines that are 3/16" but use a 7/16" fitting.

    Scott,

    Now why don't you spill the beans about the different thread pitches used, and how they aren't interchangeable.....and if you try they will leak all over the place and eat the paint off your freshly painted 14-Bolt, and will lose fluid all the way to Moab and back...?

    Oh, nevermind....I guess that was something I wanted to say.

    You might want to tell him about the thread differences though.

    interesting....

    so that would mean that Aerofit fittings would not work since they only come in AN sizes or 1/8 and 1/4" sizes (for what i am doing anyway)

    is there a way to enlarge the threads? use a different block in the rear?

    suggestions?

    Are you sure that someone didn't sell you a metric brake line? /forums/images/graemlins/shocked.gif

    I think it was more of a 37* vs 45* thread pitch....something about a military thread vs. standard or something like that....?

    Those angles sound like the flare at the end of the tube. There are two different angles for flaring a hard line. I think those are those numbers. But then again, I could be wrong. /forums/images/graemlins/tongue.gif

    Just throwing out ideas /forums/images/graemlins/pimp1.gif

    As i recall, the 37* fittings are the AN fitings.
    The 45* fittings are an inverted flare fitting for brakelines and hard lines. It's 45* for male fittings and 42* for female fittings.
    You can get adapters from summit or speed merchant. Theres a section of fittings "Brake adapters" on Pg. 47 of my summit catalog.

    Yup, John. 37 and 45 degree(I think hose are the 2 numbers but there are 2) is the angle of the bevel. The thread pitches are all the same to my knowlege since its not the thread that does the actual sealing. But I am sure there is something I am forgeting. Anything I screwed up guys?
