Last weekend I sent an email to the supplier of my braided hoses and duly got a reply on Monday.
I am sorry there was these issues with your hoses.
We do a different female fitting for some of the other BMW models and that would have been better suited, so I will have the specs changed.
I got the specs for this vehicle from HEL performance, so tomorrow I will speck to them to why they choose that rear setup.
We don't make replacement hard-lines so I can only imagine the specs where designed to remove the hard line between the 2 hoses and to reuse the existing bracket.
I am more then happy to send you some replacements with the different fittings should your wish? I would just need to find out more about these rear specs first.
I apologise for the inconvenience this has caused you.
Regards,
Liam
For someone with a British sounding name he does seem to have a problem with the language (or keyboards), anyway a pleasant enough reply so I told him I would persevere and then send him pictures of the hoses fitted and what I needed to do to make them fit.
I also told him that more info was needed in the information leaflet to clarify that this kit deletes the short steel pipe between the 2 rear hoses.
Below is the old set up next to the new 2 hose arrangement.

Apart from the large washers required as were also on the fronts, the only other problem was the male union at the centre joint was too long to keep any pressure on the mounting bridge at the joint. It would have been loose at the bracket (hope that makes sense)
So what I did was make two "nuts" to screw onto the male unions and tighten up to the union head as below.

I made these nuts by getting a joining union and placing a male union in each end to keep the shape when tightened in the vice, this also preserves the thread too, I cut two pieces off and fitted to hose union as shown.

After placing the pedal bar on the brake pedal (this moves the piston in the Master Cylinder and prevents fluid running into the cylinder and eventually out of the system when you disconnect a pipe or hose).

With this in place you can remove a pipe, hose, bleed screw, whatever, and all you will lose is a tiny amount of fluid due to the pressure in the system but nothing after that.
After fitting the new hose set up I removed the pedal bar and bled the system on the O/S/R and checked for leaks under pressure.

Where the old Flexible hose was anchored to the rear suspension arm at the joint of the steel pipe I cut some rubber hose and packed it around the new hose to allow it to be clamped back in place. See the first of these 4 pictures.

Wheels on (130NM) and a short road test out in the foggy evening gloom. Brake pedal so firm now, looking forwards to the next part of the upgrades probably just after Christmas if Shirl gets all the hints!
Tony.
ps. If you have any questions please ask.
