How to instantly stop the Unity machine?

Question

Unity

Good afternoon!
The question arose, how to instantly stop a car that is traveling at a fairly low speed using wheelColliders?

Answer 1

Pressing the space bar

public WheelCollider[] Cols;
public float brakeT = 100;

if (Input.GetKeyDown("space"))
{
            for(int i = 0; i < 4; i++)
            { 
                    Cols[i].brakeTorque = Mathf.Abs(Cols[i].motorTorque) * brakeT;
            }
}
