What happens here

During practice and the race, the driver continuously assesses the car's handling characteristics on the track. If the car exhibits 'pushing' (understeer) or 'loose' (oversteer) conditions, especially on corner entry or exit, an immediate adjustment to the brake bias can be made from inside the cockpit. The brake bias knob (seen as a yellow knob) allows the driver to shift braking force between the front and rear wheels. For example, to help the car turn better (reduce pushing), shift more brake bias to the rear.

Goal: Optimize car handling in real-time by adjusting brake bias during on-track sessions.

You saw [music] me just turn that knob up there. That's the brake bias knob. And I put around to the rear because when [music] I was going in, it didn't want to turn until I took my foot [music] off the brake. Then I've learned that that usually means you have too much front brake in [music] the car. So I put around to the rear to try to help get it to rotate better, and it did. The brake bias adjustment is about the only tuning tool the driver has that can be changed [music] during the race.
