Back in 2013 I fabricated a setup for myself and a few fellows asked me about it. So in a old thread that is still up: General > Project Logs > Galathoun's Nitro 44 Project Minibike. And on page 2 you can find a quick explanation I offered with some photos. Feel free to go to my account and look at the few other photos regarding the set up. The links for the Rear Hydraulic Assembly say they have one left, but I don't know. Anyway, my point is that I used some parts that I had laying around doing nothing and (using the now popular terminology) I "re-purposed" them. So I didn't have buy a fancy rotor or mounting hardware for it, and saved $$$ and still have quite a kick ass setup. Give it a look, maybe you get some idea's of your own.
