Interesting tool! I didn't use any tools at all to disassemble my calipers before installing, just used the worn out pads that came with the calipers first, then used air pressure to extend the pistons, took one pad out, extended them more until they popped out. What will happen is once one pops the rest will not but they are out enough to "convince" them to come out! Rebuild kits are fairly inexpensive
The best ones to get are the R1 GOLD dot ones, they have the anodized aluminum pistons that will not rust or corrode and become sticky. The blue dots have steel pistons which can rust and bind.
Not 100% sure but I think you have the years correct, I'm sure someone else will chime in...
You might want to contact Skydoc_17, he might have the caliper in stock, and he supplies the rebuild kits as well.
