The "accepted standard" for manual brakes is to use a 7/8" MC.... The 7/8" will make all the pressure you'll need and has the volume as well. The 1" will give you a firmer pedal feel - but will require more leg effort.

Make sure you understand what pedal ratio is - how to measure it - and then correct your pedal if required. It should be 6:1 for a manual brake car.

A primer on pedal ratio can be found here:

15/16" bore MC is also quite popular and common for manual brakes. I ran that for years.

Greg,
Thank you for the recommendation and link.

I would get in contact with Ron Sutton. He can evaluate your whole system and make the proper recommendations. Buying the right parts the first time will wave you a lot of headaches and money! I ended up changing my brakes at all 4 corners after we figured out that system wouldn't generate to braking force I would need for the track. I had purchased stuff I had seen written up in Popular Hotrodding, Hot Rod, etc. I probably would have bent my car up the first time at the track with the old system....live and learn!
