The first two images shown here are of one of the actual brake discs removed from the 28,000 mile Boxster S detailed in our brief case history on the services page. We should point out that the small amount of surface corrosion evident on Image 1 has occurred since removal, but Image 2 speaks for itself, as it is the other side of the same disc!
Images 3 and 4 show another vehicle with the early stages of the same problem (i.e. blocked cross-drillings), although the outside face of the disc looks fine.
