As noted in a previous post, my front brake pads were nearing minimum thickness but when inspected closely, it was clear that the discs were also in need of renewal as they were close to minimum thickness as well. On a performance car like the 535d, it would be foolish to scrimp on brakes so I ordered a set of genuine BMW discs from Cotswold BMW to fit along with the pads and wear sensor already purchased.

The fitting process was relatively easy and in fact easier than most cars I have seen.
