I need to change the rear pads on my late 97 2.8 quattro saloon.

Now, I seem to remember PeterD mentioning something about when the calipers are moved (which they need to to do the change) they weep from the banjos. The reason for this is that they didn't fit a type of washer to it? Can anyone tell me the number for this? Is it a dealer only thing?

Also, who is best for brake pads? Audi, Local factor, GSF?

Cheers
