Expert Reply:

The only thing your missing potentially is idler hubs for the Kodiak disc brake kit part # K2R712DAC to fit on which for that you'd want the # AKIHUB-865-7-2-EZ-K which comes with bearings so you would not need a bearing kit.

The Hydrastar actuator part # HBA16 is the best around so that's a good choice, and the brake line kit part # 20TA-BLKIT would work as well. Instead of the HBA16 though we have a kit that includes all of the needed electrical components as well which for that you'd want the part # HS381-9067.
