AMS2 does not always have a dedicated standalone calibration screen for handbrakes like it does for primary pedals.
If using an analog handbrake (like those from Fanatec or Thrustmaster ), ensure it is recognized as an rather than a button for smoother engagement.
This combination—increased front grip and decreased rear grip—forces the car to rotate. This is known as "induced oversteer." In Automobilista 2 , this is simulated with remarkable fidelity. You can feel the suspension compress, the rear end step out, and the need to counter-steer to catch the slide. If you pull it too hard in a car with a locked differential on tarmac, you might just spin; if you tap it gently on a rally stage, you might just save your line.
The is one of the most nuanced controls in modern sim racing. It is not an emergency brake; it is a rotation tool. Because of AMS2's advanced tire model (Adrenaline 2.0), the surface you are on dictates the response: dirt requires 50% more lever pull than tarmac; rain requires 30% less.
