Hose update:
Venhill copied and returned the hoses within a week, unfortunately that didnt measure all of them correctly:

You can also see the the mounting hole on their brass t-piece is larger. Not an issue, I just used a washer before fitting the retaining nut.
At least it gave me a chance to get the lenghts spot on by having all the Venhill fittings to hand and doing it myself

. So back they went and just a couple of days later the replacements turned up. This time they were the wrong colour and still not the lengths required. Another phone call and the next day the correct ones arrived

.
Fitting was straightforward and made easy with the swivel fittings allowing everything to self-align.
As I had cracked into both front and rear brake systems I bled from the ABS unit as well as the calipers. There is a 'clutch' style bleed valve at the headstock you could use, but I didnt bother. It can be replaced with a normal banjo bolt if you like.

In the pic above you can see I was unable to refit the rubber grommit. This is because the Venhill fitting that passes through it is a little bigger. Not a problem really.
Bleeding on the front brakes was sped up by pushing the brake pistons fully in (also reduces air pockets) and turning the bars to the left and feathering the brake lever to get the air out of the master cylinder. I also like to get all the residue brake fluid out of the nipple and threads. We all know brake fluid absorbs water, so it will encourage corrosion over time. I stick a syringe on the end of the bleed nipple and force the stuff out. Obviously this is after the system is bled and everything buttoned up.
Despite the hicups in getting the right sizes, I would recommend Venhill. They never argued the point that they sent the wrong sizes and rectifed the issue straight away. If anyone does need hoses for a evo calipered (BMW badges Brembos) non servo, but with ABS system, Venhill should now be able to supply this. As an aside, I do have risers on my bars, which worked fine with standard BM's hoses and also with the Venhill ones.
