    Ok, I have been chasing a leak from my single MC on a '65 CJ6. All the parts are new, in fact I have made the front brake line 3 times now as I cannot seem to source an already bent one that fits.
    The main joint on the brass fitting attached to the end of the MC drips. Three separate brake lines made, flares made by the Eastwood tool seem to be fine in all other locations.

    The brass fitting is apparently NLA, I don't really have a way to machine a new one.
    I've spent WAY too much time on these brakes, and they still leak. When pressing on the pedal, it slowly goes to the floor and the fitting as shown in the photos drips. One can see the drips around the threads and a bit around the tube itself. WTF? Starting with a snug tighten, and gradually tightening to "any more and it will break", NO difference, just drips.

    I have used some very fine grit and surfaced the brass fitting with an extra steel flared end. No luck. I can see that the brass was deformed from the steel line, so probably need a new part, well good luck with that.
    I should point out ALL the brake parts are new (except that brass fitting).

    So screw these parts. Was thinking of a dual MC upgrade, but the jeep is pretty much together and I have no way to remove the body. All the photos I see about the upgrade have the body removed. How difficult will a MC upgrade be with all the parts in a "normal" jeep? looks like it would be a PITA.
    Suggestions?

    So you're saying the banjo fitting leaks? I'm assuming it's deformed where the flare on the line seats on the fitting?

    yep. I have tried 3 separate lines flared with new fittings, so the culprit must be the banjo fitting.

    I've been there too with leaks, sometimes you might not notice a small imperfection. That fitting should be available somewhere I would think. Where have you tried?

    Pretty common for those banjo fittings to crack.

    That was my thought too. Walcks also has the copper gaskets in addition to the wye fitting Glenn mentioned.

    A mc conversion with body on is not a major ordeal. Unless you are a stickler for stock I'd just go ahead and convert. Far safer to have the redundancy.

    Speaking as one who has lost brakes twice on a car with a single bowl master cylinder, I agree 100%

    I did a conversion on a '67.Not much room to work.Removing L.F. fender may help.I purchased the banjo fittings as they are extra ,but it is a tight fit and they help a lot. As you can see I had the engine out for some work so that was kinda cheating. good luck mike 1967 jeep overhaul 016 (1).JPG 1967 jeep overhaul 016 (1).JPG

    Walcks has a Y banjo, which means one will need to be plugged. After what I have been through on this jeep, yet more work converting to dual MC just ain't gonna happen...someone else will get the honor.

    Where did you get the banjo fittings? Would like to not have to plug a Y, not even sure how one does that, as it is not a taper.

    I agree with having the dual master cylinder, however I'm not convinced on the safety factor if one doesn't realize that half of the master cylinder has already failed.

    You can readily buy a flare fitting plug at a parts store.

    I agree with wanting the single fitting. On another note, you did use the copper sealing washers for the banjo fitting, right? Also, some times the washers like to leak and be a pain.

    The banjo should have a copper washer each side.

    I bought the banjo fittings from "hermtheoverdriveguy @outlook.com . He also sells a conversion kit for M.C. .The flare plug is available at auto parts stores. I have a few in my drawer of fittings as they come in handy. mike
