Yet another outstanding article from K-Man S. Truly well done. I only have two comments, one a suggestion and one a nearly irrelevant quibble. The hubs show signs of substantial surface rust. If I was doing that job I would have wire brushed the rust off (wear eye protection when doing this!) and brushed the surface with a thin layer of anti-sieze paste.
My quibble is that the calipers you used are not really the correct tool for measuring rotor thickness. You need a disc brake micrometer to clear the lip and fit into the bottom of the deepest groove. Like I said, a quibble, because with those cracks shown those rotors needed to go.
Again, very nicely done.
