I pried off the bearing cap with a couple of taps with a hammer and flat screwdriver.

If you're not already wearing rubber gloves, I'd suggest you get them on now.

Remove the cotter pin and the nut cover.
(Anyone know what that cover is for and do I REALLY need it?)

Remove the nut and the rotor will slide right off.

Remove the 4 nuts (5/8") holding the brake assembly together and everything should come apart once the bolts are removed.
