Rear caliper help for Evo....
I'm going to try and ask this here as most of the more knowledgeable folks hang here. Plus, I do believe my '86 sporty shares a lot of parts with late model IH..
Does anybody know what type of brake line fitting my rear caliper takes? I thought it was a 10mm banjo, but upon a closer look it looks like a 1/8 pipe thread; does this sound right?
Thanks for any help with this.

Post a pic of it please. Yes, it could very well be 1/8 NPT. Need to see it.

Hey Mick,
Thanks for replying back... here are two pics of the rear of the caliper. the left piece is the bleeder, the right is where the brake line and fitting go...
What's happening is that the bike originally had a solid brake line from master cylinder to caliper. I hard tailed the frame, so I need a custom length line, but not sure which fitting to use... |

I am not thoroughly familiar with the terminology for brake fittings. I think the correct terminology for that fitting is inverted flair. It could be metric or SAE or NPT. I believe that it is not a banjo fitting.
If it is smaller diameter in the hole than at the top then it is NPT.
Hopefully someone who knows will come along.

I'll agree, that looks like a flair fitting. A banjo fitting would have a nice machined surface around the threaded hole. Do you have the line that came out of the caliper? Lots of automotive brake lines use flair fittings on the ends. You might take it to an automotive store to see if you can find one that fits, then you can determine the size.

It is inverted flare. NPT is tapered and doesn't have the, well, inverted flare thingy in it. Auto parts store sell a bunch of fittings for them. Mostly they sell straight sections of pipe with the flares and threaded parts already on them, and then you bend to fit yourself. Just be careful because on a bike you need some flexible hose for the chain adjustment, and watch for crimping when you bend it.

One reason is over here in the IH forum your talking with a bunch of old farts that have been around these bikes along time.

I can't see in the hole really well but it doesn't look like the inverted flare surface I've seen in my other brakes. Almost looks like a brass insert of some kind in there. Anyway, the inverted flare thread size would be 3/8-24 and I'd buy a 3/8-24 bolt and see if it threads all the way into the hole. If so, you need the inverted flare adapter for your hose. If the 3/8-24 bolt won't go in smoothly, you'll be dealing with a 1/8-27 pipe size adapter.

The Evo section has good people. They just do not have the technical knowledge and experience that the IronHead guys must have. |
