Can't do that. A disk/drum MC will have one large reservoir and one small (disks take more fluid to move). Also, you need a residual valve on each port that will service drums (disk brakes can't use a residual valve).cmayna said:If there's any plan to put discs up front, I wonder if disc/drum MC would be the way to go. Maybe you can't do that. Obviously if you are not planning to go disc then just pick up a drum/drum MC.
I wouldn't think a prop valve is needed if you are not using discs. Hopefully others will chime in to help clarify which way you should go.
