There are five bolts that attach both hubs to the wheel. The same five bolts go through a hub on one side, then through the wheel, then the hub on the other side. The head on these bolts is an allen head and I believe a 9/16" nut on the opposite side. After you remove the five bolts, then you can see how the rotors are attached to the hub. They are held on to the hub with about 10 studs with spring washers and "C" clips. When you disassemble it, don't just throw all the studs, washers, clips in a pile or you will have a mess.
Note: Make note how all this is arranged when you disassemble. I would stick the stud, spring washers and "C" clips back together temporarily as you disassemble or arrange them on a piece of cardboard or something so that you can keep track of all of it. If you don't keep track of all this hardware, as you disassemble you could loose track of how many you put where, etc. ASK ME HOW I KNOW, lol!!!!!!!!
