2002 S6 Avant rear rotors

[Grant Lenahan]

Oh wise ones,

So, yesterday I tackled the relatively easy task of rear rotors and 
pads on my '02 S6 avant.

One problem - The rear rotors would not come free.  In fact, they were 
so tight, and the fit between them and the hub so clean, that we began 
to wonder whether the rotors I received (which look right, and have a 
large, 2 5/8"+, hole in the center to clear the hub face) were wrong 
and if the hub nut must come off to release the rear rotors.

- Bentley simply says remove rotors
- rotors I received appear to be retained by nothing more than lug bolts

- BUT, neither pulling nor hammering/heavy tapping (on the back of the 
rotor) released them...........

Rather than damage something, and since the rotors were really in 
pretty good shape, I left them be and just did the pads.

Any experience here?  Just hit it harder, or are my rotors wrong, or is 
there a trick.
