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 driver presses the brake pedal. When the brake pads clamp down on the rotors, friction is created, which helps to reduce the speed of the wheels. There are different types of brake rotors, including vented, slotted, and drilled rotors, each designed for specific driving conditions. Regular maintenance and inspection of brake rotors are important for ensuring safe and effective braking performance, as worn or damaged rotors can lead to decreased stopping power.
