Does anyone know the part number for a S4 B5 HP2 caliper rebuild kit as shown in the "A4mods.com caliper rebuild how-to". Mine are the later HP2s with the aluminium housing and top retainer clip for the pads, earlier version had no pad clip on the top and steel/iron housing (i think it was steel or iron).

I've emailed A4mods but no answer yet.

Thanks
