Jeff is right about the T60 you can snap them trying to get the bracket off. In my trial and error though, I discovered that using a small propane torch will help you get them off without much force at all. It appears that the bracket bolts were threadlocked from the factory. Threadlock Red is designed not to release the threads until the surrounding material reaches a certain temperature. Heat them up with a torch, they come out pretty easily.

Do yourself a favor, and threadlock them when you put the bracket bolts back in. I didn't the first time, and even though I used a breaker bar to snug them up, while I was driving home a few weeks later, the lower left bolt still came out of the bracket, the caliper moved up and my brake pedal went to the floor.
