When I started this project there were NO brakes in this car.
I thought I wanted power brakes so I bought all the pivots, clevis, master, booster, firewall support plate, and a speedway rear disc conversion (I hate this kit by the way) but anyway, my brakes work real good. I had to install a manual valve to be able to adjust the bias to the back brakes but as far as I can tell it's working fine. I am prepared to change that

I did the math and science before I bought the power brake set up and it dictates the system requires a 7/8" bore master and I have an 8:1 pedal ratio

Fast forward .... I have decided to put a blower on the engine and I want to clean up the look and go with a manual master. I would like to keep the power brake mechanisms under the dash and find a master that I can bolt up, air bleed and just go.

What suggestion do you have for a manual master?
