    Resurrecting an old thread on exiting brake lines. Has anyone have any experience with or pictures of these covers installed? They certainly aren’t cheep. I’m trying to avoid running new braided -4 lines out the bottom center of the fuselage. It needs to be set up for float and ski changes so running one continuous line isn’t an option. There needs to be an easily accessible union or bulkhead fitting.

    Yes, a friend's wife pulled some carbon fiber ones off a set I had. They come out at the gear leg and the grommet for them is shown on the covering drawing. Piper brought them out at the longeron just behind the front gear attach.

    I think that’s the best place. Have them exit below the longeron on aft side of the fwd gear fitting. I’m betting the above noted cover plate gets thrown away at rebuild because I’ve never seen one. I kind of wish I had an example because for $90 bucks I’d be inclined to make a bunch.

    One of the benefits of rebuilding 5 unmolested, original Super Cubs. The fair really isn't needed but I like them just because they were original. I think there is a picture in one of the Annual inspection videos I did.

    Brake lines, bummer, does anyone have a parts list for making their own brake lines? $146 for a 14 inch brake line is ridiculous! I had a hose shop make new lines for me a few years ago and today tried to put it on and learned that they used the wrong flare so I am STUCK! Thanks in advance!

    JIC fittings from a hydraulics shop will work if AN fittings not available. They're 37 deg. The automotive SAE flare is 45 deg.

    Here's more than you ever wanted to know about that: https://en.wikipedia.org/wiki/Flare_fitting

    had two brake lines made by a hose shop a few years ago with 37 degree fittings (or so they said). Could not get them to stop leaking so called a different hose shop and drove about an hour and a half. Same story but fortunately this time, I did not buy their fittings. They said that I just didn't tighten it enough. Came home, put those hoses back on and really tightened them. No luck, more hydraulic fluid on the floor. Gave up, bought two $147 14 inch hoses from a supplier and son of a gun! No leaks! What a waste of money and time. Thank you for your input and thanks for the tutorial. MK

    Hydraulics shops use JIC fittings because they’re steel. AN fittings are aluminum. I order AN3 or 4 and get steel fittings on the hoses. I’ve had no issues mixing the two.
