I actually just replaced my rear rotors a week ago. I found a few videos, including this one
, but I couldn't find any that fully matched or showed the entire process. A couple of tips that for you though.
-The star tool (if that's what yours has) is a size T50.
-Removing the outer portion of the caliper separately (leaving the inner portion connected) is the easiest and best way of doing it. This allows you to remove the hand brake.
-Removing the hand brake wasn't obvious to me, so a tip on that. Push on the two tabs within the bracket and twist the cable, that holds the tabs. Then push the brake lever and pull the cable out. Then simply twist the caliper and pull the cable through the cable holder.
-When putting it back together. I put one side of the springs into the pads, then slightly slid the outer caliper over them. This held the pads in place while I had popped the other side of the spring into the second pad. It took a few tries, but it worked.
Hope that helps!
