What is the purpose of brake pads?

The primary purpose of brake pads is to create friction against the brake rotor. When the driver presses the brake pedal, hydraulic pressure is applied to the brake pads, which then clamp down on the rotors attached to the wheels. This friction between the brake pads and rotors slows down or stops the vehicle. The ability of the brake pads to generate sufficient friction is essential for effective braking performance, ensuring safety while driving.

Other options touch on different vehicle functions. For example, cooling the engine while driving is related to the vehicle's cooling system, not the braking system. Supporting the vehicle's weight is a function of the suspension system and the chassis. Absorbing shock from the road pertains to the dampers and shock absorbers, which help maintain ride comfort and stability. Each of these functions is essential for the overall performance and safety of the vehicle, but they do not define the specific role of brake pads in the braking system.
