The primary component responsible for creating friction to slow the vehicle is the brake pads. When you apply the brakes, the brake calipers squeeze the brake pads against the brake rotors, creating friction. This friction is what converts the kinetic energy of the moving vehicle into heat energy, thereby slowing down or stopping the vehicle.

Brake rotors are essential parts of the braking system as they provide a surface for the brake pads to grip. However, they do not generate the friction on their own; they rely on the brake pads to do so. Brake lines are crucial for delivering brake fluid to the calipers but do not participate in friction generation. Brake calipers act as the mechanism that holds and moves the brake pads against the rotors, facilitating the braking process.

In summary, while all these components play vital roles in the brake system, the brake pads are specifically designed for the purpose of creating friction, which is fundamental to the slowing or stopping of the vehicle.
