Brake pressure

If you're monitoring brake system pressure on a dual-circuit master cylinder, which circuit do you use, or does it not matter? As far as I can tell, my Porsche 911 is split directly front & rear, not diagonally.

It depends on what you want. If you purely want to do driver coaching/learning then it doesn't matter (but probably just front as you'd get a larger spread of pressure therefore easier to detect small differences).

If you're doing car monitoring and need to know about exact brake pressures to determine problems then you'd want a sensor on both lines.

Hope that helps!

What size pressure gauge would need to be installed? I have no idea what kind of pressure to expect from say a Miata brake master cylinder.
