Brake rotors are a component of disc-brake systems, which use hydraulics to slow down and stop an automobile. When the brake pedal is depressed, brake fluid applies pressure to the rotors, causing the brake pads to tighten on the rotor. The rotor is a smooth metal disc, polished on two sides, on which the brake caliper holding the discs attaches to, with one disc on each side of the rotor. Poorly maintained rotors often rust over time and require corrosion removal to ensure the brakes operate properly and safely.
