My 01 s4 has 330mm rotors with brembo 4 piston calipers. The pads and rotors are completely shot and squeel like a pig! The part #'s on the calipers are very hard to read so I can't really help with that. I have been searching the web for a good while with zero results in finding pads for these calipers. If anybody can help me find some brake pads, that'd be such a help.
