Brake disc, also known as a brake rotor, is a crucial component of a vehicle's braking system. It is a flat, circular metal disc that is attached to the wheel hub and spins along with it. When the brake pedal is pressed, the brake caliper squeezes the brake pads against the brake disc, creating friction and ultimately slowing down or stopping the vehicle.Brake discs are typically made of cast iron or carbon composite materials, which are highly durable and heat-resistant. They are designed to withstand the intense heat and pressure generated during braking to ensure safe and efficient stopping power.The surface of the brake disc is often grooved or drilled to improve heat dissipation and prevent the build-up of gases and debris that can reduce braking performance. These features also help to maintain consistent and reliable braking performance in various driving conditions.Regular inspection and maintenance of brake discs are essential to ensure their proper functioning. Over time, brake discs can wear down or become warped, leading to decreased braking efficiency or vibrations during braking. In such cases, it is crucial to replace the brake discs to maintain optimal braking performance and safety on the road.
