Brake rotors are essential components of a vehicle's braking system. They are flat, disc-shaped metal parts that work with brake pads to slow down or stop the vehicle when the brakes are applied. When the driver presses the brake pedal, the brake pads clamp down on the rotors, creating friction that slows the wheels. There are different types of brake rotors, including solid, vented, and slotted designs. Vented rotors have internal channels that help dissipate heat, while slotted rotors feature grooves that improve grip. Regular maintenance of brake rotors is crucial for safe driving and optimal braking performance.
