Yes they can make a grinding noise, if they are bad.
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.
your barrins in the wheels
You probably have something wrong with your engine, or brakes. You should really have that checked.
lol change your brake pads they make a grinding noise when its time to replace
Its kind of a grinding screeching metal on metal noise.
Check the idler pully.
The starter could grind if the bendix is sticking
It could make a grinding type noise when moving slow. A "whirrr" type whine when moving faster. The grinding noise may change to a clunking noise when turning the wheel. Any of these noises means "fix me now or else."
it could be belt pulley rubbing on the timing belt cover or it could be the berries in the wheel but if its making grinding noise while ilding then def check your pulley make sure it isn't rubbing on anything or it could be the flywheel theres numbers of things to check over for the grinding noise
The grinding is a worn CV joint. Get it replaced before it causes more damage! A worn wheel bearing will make the same noise answer worn wheel bearings or worn brake pads will be the cause
We would need to know where the noise was coming from and under what conditions it made the noise in order to make an assessment.
