Does anyone know where I can find some aftermarket replacement pads for the fronts for this kit...

Brembo 6 Piston "M" - as in monoblock Calipers (Audi A4). I have been unable to find a non-brembo pad and the brembo ones have too much dust and at $400+ just for the fronts I would like to see if any other pads with less dust would fit the M calipers.

Thanks.
