I'm confused. I've been around Spridgets for many years and I'm planning to build two Bugeyes with disc brakes. One will use a later pedal box with separate brake and clutch cylinders for a single circuit brake system as found on '67 cars. The other will use a combined brake/clutch cylinders. Years ago I bought a combined master cylinder for a '62 Mk II Sprite with drum brakes. I never finished that car, so I planned to get that cylinder sleeved to 3/4" for my new project. I have also bought two pairs of later Morris Minor 3/4" bore rear brake cylinders. Today I read on the BugeyeGuy website that he actually prefers the 7/8" bore master cylinders for disc brake cars. Any opinions would be appreciated. Thanks.
