Hello I will help you with your question,
You will need to remove the Torx headed bolts shown at location #3
So that you can remove the caliper mount then remove the screws holding the rotor to the hub.
Be careful as these were designed by the same engineers that design fighters and the bolts are easy to strip/break if you do not have a tight fitting socket
Let me know if you have questions
A can of PB blaster and a torch to heat the area around the bolt. As I said the "engineers" leave a lot to be desired. If you break one off you are no worse off. You will still have to drill it out and clean the threads up.
Soak the bolt thread with the PB and leave it over night . Its pretty amazing stuff. You can get it at any big box or autoparts store. Tap (hit) the bolt head to shock the corrosion and try to loosen it. If you still cant get it loose you will have to try heating the area around the bolt.
