Brake LIne Pressure Question

[strictlypersonl]

The pedal ratio is 6:1. My spreadsheet " brake balance calculator" shows that 150 lbs at the pedal will result in about 1G deceleration. That is a little high for people who are accustomed to power brakes. I'm working on some slightly smaller bore masters, but I am really careful about having enough volume for every circumstance.

Just as Bob is, you should also give careful thought to these modifications, in particular if you are using OEM calipers with their larger diameter pistons and larger required fluid volumes both for braking and also to compensate as friction surfaces wear. A lack of attention to these kinds of design / engineering considerations can result in a crash or worse, loss of life for someone who is not at all involved — and that would be on you! If you do not know how to do the design / engineering required then you should buy the professional services of someone who does.
