What effect does using worn brake pads have on braking performance?

Using worn brake pads has a significant effect on braking performance, specifically leading to reduced stopping power. Brake pads are essential for the friction needed to slow down or stop a vehicle effectively. As brake pads wear down, their material becomes thinner, which diminishes their ability to create adequate friction against the brake rotor. This reduction in friction directly impacts the vehicle's stopping distance, meaning that it will require more distance and time to come to a complete stop.

In addition to decreased effectiveness, worn brake pads can also lead to other issues, such as overheating of the braking system, increased wear on other components, and potential brake failure. The reduction in stopping power compromises the safety of the vehicle, as it cannot decelerate as quickly in response to driver inputs, which is critical in emergency situations. Therefore, the statement regarding the impact of worn brake pads highlighting reduced stopping power accurately captures the fundamental principle of brake system functionality.
