You really don't even need to take them off that way if you're going to be removing the whole rotor. I'd just remove the caliper by removing the entire bracket as well. There are 2 bolts on the back of the hub. I believe they're 14mm, but they could be 17mm. Take those off and the entire caliper assembly comes off. That way you can remove the rotor without having to mess with getting it around that bracket.

hih
