Awesome walkthrough, thanks. Of course no part exposed to the elements is easy to remove on a Subaru with 140k New England miles on it. Like Max Capacity, I had to remove the hub and backing plate together, then encourage them to separate with PB Blaster and a 3lb hand sledge.
Also, the rotor was very difficult to remove, had to retap the M8 bolt holes and use some long bolts to force it off the e-brake. One left to do, when I can face it again...
