Sergey's point is very valid. We all expect the source to be the front. But his was obviously not.
The 3000miles issue may be explainable by the fact that when new, the tolerances are such that the vibration/judder cannot occur but, after a bit of wear, the pads (or whatever) have sufficient movement/slack to start the judder. Maybe.

Spoke to Owen yesterday and booked the car in for next Tuesday. He has all sorts of gadgets to test brakes, skim discs in situ and check disc temperatures. I feel that he'll look into the cause of the problem, rather than just keep replacing parts.
Thanks for the pointing me in this direction folks!

This is exactly the same problem I'm getting on my FL S8. Juddering after about 3000 miles. I've been using EBC Turbo grooved discs and yellowstuff pads but its always the same: Judder, skim, 3000 mile later more judder, skim. It's now getting rather monotonous. I've rebuilt the calipers, which was easier than I thought it would be, but no difference. I've changed pads, discs still no difference. Sadly, in Dubai we don't have anything as sophisticated as Procut but there are plenty of Bodge-It, Fleece-'em and Scarper machine shops that will make matters worse.
I'm convinced the problem is with the front brakes as when moving quite slowly and applying the handbrake there is no judder at all. One avenue I am pursuing is regarding the front wheel bearings. I had one changed about three years ago and this judder has only occurred since then. The wheel bearing itself comes in a housing that once the hub has been pressed in it is then bolted to the steering knuckle. If this housing has been bolted into the knuckle slightly out of line then this would create a slight misalignment between the disc and the calipers/pads. This could, I think, cause uneven wear which could cause judder. What do you guys think?
