I see ! OK , how about drilling our the caliper and tap to 1/2"-20 , then use a reducer bushing to get to 3/8or 10mm. With the sealers that are available today , ID think that would be doable , I've seen those work on heavy equipment fittings where the hydraulic pressures are way above a brake system ....
Course I've welded hydraulic supply lines too .....

90 degree "not side bend" banjo:
|02-17-2020 08:35 AM|
It appears that you have a full aftermarket suspension , does it incorporate steering stops that limit the turning radius ? Could be that limiting the turn could provide the clearance you need , if its within reason ....
BTW Russell performance has all sorts of different banjo fittings ...

|02-17-2020 05:34 AM|
Unfortunately there aren't any 7/16 banjos with side bend.
But drilling out the 1/8 NTP inlet port to something else, might be a good idea.

The calipers are not left/right spesific.
Bleeder and inlet ports are both 1/8 NTP

|brading||The Red 180 dec fitting is connected to the caliper as per hose #9.|
|02-14-2020 05:04 AM|
|brading||This is how I would get over the problem.The Purple is a bracket welded to the top arm to hold the Green Bulkhead fitting.The Yellow is a bend fitting. The Red is a 180 dec fitting. The Blues are flexible hose crimped to the fitting.|

|brading||Staleg could you post a picture similar to the the one you post in #9 but showing the full suspension|
|02-13-2020 09:13 AM|
|2old2fast||You could spot face the caliper and drill and tap the existing 1/8 npt hole for 7/16-20 threads making it possible to use standard banjo fittings ....|

The key is that a banjo bolt will tighten against the caliper, crushing the copper washers on either side of the banjo fitting. The seating area on the caliper would be machined square to the threads and there should be small annular ridges machined to cut into the copper washer between the banjo fitting and caliper.
NPT would seal by mechanical interference between the threads as it is tightened , the interference increases as the fitting is tightened. This could make clocking problems if you were to use an elbow.
There is BSPP british straight parallel pipe, I believe has the same dimensions as NPT & NPS thread, but has collar nut to tighten against the caliper after the fitting is positioned (clocked). This requires a small chamfer at the lead thread, were an o'ring is squeezed into, as the seal. If it lacks a chamfer, there are steel washers to contain the o'ring while the collar nut is locked down.
BSPP would also require that there be straight thread in the caliper and that there was a flat area around the hole. But would cure any clocking issues for an elbow.
If you dont use an elbow, then there is no clocking problem. A NPT fitting is adequate for the pressure in the system and should be fine except you would have to use a steel fitting. Brass fittings tend to crack at the base of the thread.

And The Allstar hoses are not DOT approved.
The 90 degree adapter in your link is not possible to fit, because there are not enough space around the inlet port to screw the adapter in place.
Besides that, using this adapter would also turn the AN fitting in a direction that would increase the risk for it to be loosened by the up-and-down spring movement. To avoid this effect, one can add a small bracket close to the caliper end of the hose, but with sliding calipers this bracket would have to be fastened in the caliper itself, which is not possible.
But thank you for trying.

staleg....mayby there's a solution available. I don't know how much more clearance you need but perhaps a 90 degree 1/8" NPT X AN-3 or -4 adapter like this would help tighten things up a bit for clearance? It could be used with a brake line with a straight end to keep everything closer to the caliper.
Another possible solution would be a brake line with a forged end rather than a sweeping elbow version as you have pictured. One like this?
The one in the link is a AN-4 line, 18" long, but they're available in various lengths and also in AN-3 fitting and line size.
Just a thought. Sometime just a bit more clearance is all that's needed.

Thank's for the information. I have given up this project.
The calipers will be used as door stoppers or dust collectors.
My own fault, as I didn't do enough homework before I bought them, and bad luck that I painted them before I discovered the hose routing problems, so I Speedway won't accept a return.
The photo shows the common plumbing for them, but this interfere with the lower A arm at full turn and top end point of the suspension.
I know many would live with that, and if it was the flexible part of the hose that hit the A arm, I wouldn't mind either, but it's hard end that interfere.
Another possibility is to switch around the brake hose and the bleeder.
I prefer not as you have to loosen the caliper and turn it upside down when bleeding the brakes.
