Disc Brake Rotors

Disc brake rotors are spherical parts that are attached to a car's wheel hubs. Together with callipers and brake pads, they are a component of the disc braking system, which slows or stops the spinning of the wheels. The brake calliper squeezes the brake pads against the rotor when the brake pedal is depressed, causing friction that slows or stops the vehicle's motion. The rotors must endure the high temperatures and forces produced during braking and are often composed of cast iron or a comparable material. Rotors can deteriorate and lose their effectiveness over time, necessitating replacement.
