Morning gents. Bought my mrs a 2002 a4 avant 3.0 quattro a few weeks back (B6 PLATFORM). The brakes are suprisingly good on them! I have checked and all the components are OE and not supped up aftermarket parts. I know that the B6 uses 312mm discs opposed to the B5's 288mm but are the B6 calipers different (bigger/reworked? etc...). I had 312mm setup on my b5 and the braking was nowhere near as good! And that was with newish brake parts too.
