Brakes
What would cause a grinding noise after a tire is replaced and the brakes are not worn?
It's your vehicles way of telling you to change your pads. If the grinding noise is present when you use the brakes, the pad is almost gone. If the noise is present after the brake has been released you're getting close to damaging the rotor and you need to put pads in asap.
Normally a rusty rotor would not make a grinding noise. A grinding noise from the brakes usually indicated that the pads or shoes are worn down.
