Well I hope that fixes your problem for good.
I too had the same problem that you were describing and in fact still do. I had my disks/rotors (which aren't made by Brembo by the way, only the caliper and pad are Brembo) swapped last year which also fixed my problem initially.
However (and I hope this doesn't happen to you) the vibration came back 2 weeks later. The dealer looked at my disks and then sent pictures to triumph and noted the disks were pitted. They said that this pitting was causing my judder but refused to do anything about it, despite it happening 2 weeks after they were new.
I have found that over drier periods (which doesn't happen very often in the UK), and if I break hard and often the problem goes away, but it always comes back when its wet again.
So basically I think that under my normal ridding (I commute on my bike, so don't ride it hard as much as I would like) the disk being made out of cheap material, corrode faster than I wear them. But if you can wear them faster than they corrode you wont see the problem.
Hope that helps - I do feel your pain
