is any one out there running manual brakes with the wildwood 261-13626 wildwood 15/16 bore master cylinder and the wildwood 4 piston disc brake calipers on front and rear of their tri fives? I currently have the wildwood disc front and rear but have the cpp master cylinder with the 11/8 bore and 7 inch booster and not enough vacuum so I'm thinking of switching to the manual setup and would like to hear some feedback. any response would be greatly appreciated. thanks.
