Not even sure if these two issues are related, but would be interested to find out any possible causes.

I had new Delphi brake disks and pads fitted a few months back, which were fine for a month or so, then began juddering under braking. I took it back to the garage, who replaced them with Brembos as they said the original disks were warped. However, these new disks also developed the same problem after a couple of months, and now I'm not in the same country, I can't go back to the garage.

The juddering is barely noticeable in normal driving, but when braking from 70MPH+ it's extremely obvious. I've also noticed a clicking sound which is particularly pronounced when turning right, less so when the wheel is straight, and completely disappears when turning left. You can't hear it at all with the windows up, but it's very obvious when the windows are down.

Any ideas what could cause this? I'm currently leaning towards replacing the disks and pads again with EBC items, along with all 4 wheel bearings, as it's a cheap and easy job, but would rather not spend the money if it won't solve it.
