A common maintenance procedure for brake rotors is resurfacing or replacing them when they are worn beyond their minimum thickness. Brake rotors experience significant wear over time due to the friction generated during braking. When the rotor surface becomes uneven, warped, or worn down to a thickness that is below the manufacturer’s specification, it can lead to compromised braking performance, such as vibrations or reduced stopping power.

Resurfacing involves machining the rotor to create a smooth surface, which can restore its functionality and extend its life. However, if the rotor is excessively worn or damaged, replacement is necessary to ensure safe and effective braking. This procedure is essential for maintaining the overall braking system's efficiency and safety.

Other options, such as painting the rotors or installing new brake pads without addressing the condition of the rotors, do not adequately address the wear and performance of the rotors themselves. Adjusting brake fluid levels is important for overall brake functionality but does not directly relate to the maintenance of the rotors.
