Do worn rotors make a noise?

Yes, worn rotors can produce noise, often manifesting as squeaking, grinding, or pulsating sounds during braking. This noise typically indicates that the brake pads are wearing down and may be making contact with the rotor's surface or that the rotor itself has developed grooves or uneven wear. If you notice such noises, it's advisable to have your braking system inspected promptly to avoid further damage and ensure safety.
