Master Cylinder issue?

[Ralph140]

I have a 72 FJ40 with a 77 fj40/55 MC, booster and disc set up. Does anyone know what the line pressure should be to the front front disc brakes? And also what it should be for the rear drum? The system seems pretty close to right on. I just am not satisfied that I have all the brake that I should.
Thank you

Wouldn't line pressure depend on how hard you put your foot down?
