You could always return the hoses for a refund. Brakes are crucial. If you think they're not quite right,
then they are NOT right.
As we're dealing with R65 conversions, components from R100RS etc, often do not fit, especially brakes. Which I found quite dissapointing

.
Metal brake pipes must be supported properly at BOTH ends otherwise vibration will cause them to whip about with, possibly, bad results.
Did I mention that the original R65 lower brake hoses are still the correct length for the RS fairing when the 'distributor' is mounted under the headstock where the horn used to be (You will need a slightly longer upper hose though).
I see your upper brake hose does not connect to the 'distributor' with a banjo fitting, this may complicate siting of the 'distributor' where are you planning to mount it?
As you know, I'm happy to share my experience of RS conversion, (including hose fittings, types and sources) just ask.
Generally, I over-engineer, working, I hope, at least, to the same quality BMW did when they built the bike. This means that time, costs and difficulty are always of secondary importance to safety.
So I take my time and progress slowly.
And occaisionally spend money on the wrong equipment which I can't use
Keep up the good work
