Hello everybody,
I just slip into this thread to give a few explanations about that, as it is concerning the brake lines I supply.
I know this 45° is actually a bit tight, but as TT says, a small notch in the upright RU2 is easily doable and will not affect its strength. I think it might be a good idea to live 1mm clearance between the stainless steel tube of the 45° fitting and RU2 plate. Stainless steel should be harder than the upright steel, and I guess it will not get worn out anyway, but better preventing it by leaving a small gap.
For those who are wondering, the reason I propose the rear brake lines with a 45° fitting is to avoid the need of welding a small bracket on the upright and use a piece of copper pipe and 2 fittings as it should be done according to the book (as you can see on this
page of my website, or here under). I still think it is worth it

I actually made the first tries of this 45° with a Swedish builder, and first I thought is was tight just because his uprights were not exactly according to the books specs (as you can see on this
page of my website, or here under, the outer edge of RU2 is more “vertical” if I can say so, so a bit closer to the wheel cylinder).

So I was convinced that with a books specs RU2, it would be enough clearance. When I realized a small notch on RU2 will still be needed, I asked the workshop (at Exact) if they could bend the stainless steel tube a bit closer to the threaded male nut. Unfortunately they can't, as they use a tool (kind of a jig) to bend the tubes, and can't change the specs. There is unfortunately nothing I can do about that.
I could not try the 45° on my own Roadster as I have Phil's uprights (Talonmotorsport), on which RU8 is cleverly set at 30° and so give plenty of clearance (the other upside being that they can be used for both drum and disc set-up). Having these uprights on my chassis I had my rear brake lines made with a straight fitting, exactly like the front ones.

So these are the explanations, sorry if you guys have to take the grinder, but the needed notch is really not more than a couple of mm. Hope these explanations will help you and following visitors to understand why there might this tiny clearance problem with the 45° fittings.
Bye, and happy new year 2013 to all of you!
