Hi Colin,
Just by way of information.
I have twin ap racing master cylinders with adjustable balance bar and 10lb residual valves on both lines also m/c's below height of slaves.
M/c's started as 0.625 but changed to 0.7. pedal ratio is currnently 6:1. I can generate 1200psi line pressure without very much effort as measured with a Wilwood test guage. Could generate more if I pushed the pedal very hard but dont need to. Linings are arched by supplier as part of their racing service and double checked by me to the actual drum using my bedding in tool. Very little bedding in required, just a check really, compared to off the shelf commercial shoes.
I also changed from Silicon to Mineral fluid and accept I will have to flush annually.
If I'm brutal I can lock the wheels and thats on racing rubber. The balance bar allows for ideal set up for the prevailinbg conditions.
Not very 'vintage' agreed but a lot more confidence inspiring!
