Trying to source the adapter honed development used for their porsche calipers.  Its a metric bubble flare that goes to a female fitting for a banjo bolt.  Looked around for hours last night and came up dry.  Also tried to email honed, but they havent responded.  Any one here have a super cool place that they think would sell such an adapter? Link to what im looking for https://honeddevelopments.com/product/honda-porsche-brake-caliper-mounting-kit/.  The adapters are pictured.

Are you sure it goes into a banjo? I aske because it looks like a plain adapter to a different line size.

In their description it says it's an adapter to go from the caliper to the stock banjo bolt of the factory soft line.

I wonder if that is just a generic bubble flare to double flare adaptor.  That should seal up just fine against a crush washer.

 

Personally, using a banjo fitting without a way to positively keep it clocked gives me the heebie jeebies.  There's nothing to keep forces on the hose from working it loose.  Is there any chance you could use a different hose with a straight fitting on the end instead of a banjo?

Other options would result in custom soft lines.  Likely using a a bubble flare to male AN adapter.

Curious why you mention "nothing keeping force on the hose".  If the banjo bolt is tightened enough to seal. Wouldnt that be keeping or from moving the same way it works in any other situation?

Normally banjo fittings either have a flat that butts against a ledge on the caliper, or a tang that fits in a hole in the caliper.  Without that, you could loosen the banjo bolt by pulling on the hose, rotating the hose and bolt.

 

What is the application?  There's got to be something that could work if it came to that.  All the same, those adaptors are probably just generic bubble flare line adaptors.  If the flex hoses take a 10mm banjo then the threads are probably 10x1.0.

Very similar application to what honed is doing.  Except in my case its boxster calipers going on the front of a 1st gen neon.

Ooh, yeah, that IS weird, because those may actually be 3/8-24 fittings at the other end of the hose.  Chrysler avoided metric for as long as absolutely possible, like they had a warehouse full of SAE hardware they had to use up...

Main issue is porsche used a hard line from the caliper to a soft line.  In my stock neon form, its soft line right off the caliper.

Gregg Distributing up here is licensed to build brake hoses to your specification.  3/8-24 on one end, 10mm banjo on the other likely wouldn't be an issue for them.

Canadian company, but they can't be the only people in the world that can build brake hoses.

I'm thinking that's what I will end up doing

Possible to have a short flex hose and hardline, to mimic the Porsche setup?

 

Mazda did that on the FC.  The cars could have a sliding single piston caliper or a fixed four piston caliper depending on trim.  The sliding calipers had a flex hose going from the chassis to the caliper, the fixed calipers' flex hoses stopped at the strut and had a short hardline.

 

I am also speaking from the assumption that hardlines are super easy to make at home using whatever fittings you need at either end.

I have an awesome neighbor that has the badas* Eastwood flaring tool.  So hardlines aren't an issue.  But, this would still present an issue of needing to replace soft lines as well.  I was hoping for more of an off the shelf solution.  But when I'm trying to mash these parts together, why should I really be worried about that?
