Hi everyone,

I’m designing the brake system for our new car for 2019, but I have a few questions.
We are running dual outboard in the front and single inboard in rear without a full aero package.

According to my calculations the pedal force required for us to brake at 1.8g is 121lbf while braking at 1g is 144lbf.

Intuitively this doesn’t make any sense because the pedal force should be vice versa... higher pedal force for higher braking g’s.

However, mathematically I can see why it is this way because braking at 1g would require more braking force in the rear... and since we run single inboard, one caliper in the rear isn’t as effective as two calipers in the front. That’s why braking at 1.8g requires less force.

Am I doing anything wrong here? Also it’s impossible to be able to have a 50/50 brake bias at both 1.8g and 1g. What case should I focus on?

Thanks a lot!
