take off '1','2',3'' and under '2' there should be be another bolt the exact same size, take that off aswell. make sure you clamp the hose that leads to '3'. If your not changing the calliper or something then just leave '3' connected.
As for the rotor, once the calliper is off, just get a decent sized hammer and give it a decent whack, emphasis on decent, on the face (around the stud bolts and centre) 'ie: in the area that u've put small cirles in', and it should eventually loosen up and u can pull it off.
pretty sure that's it from memory.
