Will Shimano XT M-765 Hydraulic Dual Control Levers work with Hayes HFX-9 Carbon Cailpers? Also can Hayes 6 in. rotors work in place of center-lock rotors? I don't have center-lock wheels but I am considering buying XT Calipers with my dual control levers. If I do get dual control levers with Hayes HFX-9 calipers will I need certian brake fluid or can I use DOT 4?
