One more brake line question
« on: Friday,April 13, 2018, 12:39:04 PM »
Is it possible to use a straight banjo fitting on top of the 4 way brake thing. That way I can come in straight and not have that big lope on top.  Not my photo

It might work, but it's very unusual to install a banjo on a junction like that so I'd be very careful. If the junction has a machined surface, I would feel more comfortable about it. In any case, I'd try to pressure test it first. You could close off one of the ports and pump air in the other and test with some soapy water.

Tom,

I agree with BDA on the need for a machined surface for the banjo. IF you really need a banjo due to clearance issues make sure that the diameter of the 4 way flange is wide enough for the banjo ( think master cylinder port diameter).

I'm currently in the middle of another brake M/C conversion project and have done a bit of research on banjo adapters. There are banjos with 3/8-24 bolt threads but only come with AN/JIC 37 degree flares. I don't see why you can't use a banjo as long as you can make 37 degree flares for the brake line. Automotive flares are 45 degree flares and are not compatible with AN flares.

Thanks. Guys. Forgot about the machined surface.  I could do a 90* swivel male bubble fitting if they make such a thing.  Wouldn't be such a big loop. Otherwise I'll just do like the pictures.
Thanks for the info.  Tom

Use solder-on banjo fittings, silver-solder of course.

How about a plain ol' 3/8-24 elbow?
