B7 RS4 cab rear discs and heated rear screen

[sjo]

Hi Folks. I am looking for a set of rear brake discs and pads for my B7 RS4 Cab. Any advice on best deal/type/offers? They are pretty expensive from my Audi dealer.

Also - my rear heated windscreen isn't working. Only the bottom two wire lines seem to be working. Any advice on how to fix this or replace?

Thanks in advance
