Brake rotors, also known as brake discs or pads, are an essential component in a vehicle's braking system. They are located on each wheel and work to slow down or stop the car by converting the mechanical energy of the applied brakes into heat energy through friction with the brake pads. When you press your foot on the brake pedal, it causes the brake calipers to squeeze the brake pads against the rotors, creating resistance and slowing down or stopping the car. The amount of wear and tear on brake rotors depends on various factors such as driving habits, road conditions, vehicle weight, and maintenance practices. Worn-out brake rotors can reduce the effectiveness of your brakes, leading to longer stopping distances and potential safety hazards. Therefore, it is essential to inspect and maintain brake rotors regularly for optimal performance and safe driving.
