I just don't understand that...
It's not like the noise was all or a sudden happening... for something like grind the rotors to the cooling fins, it'd have to be happening for months...
I saw a car whose aluminum wheel were rusting because the pads were gone, the piston from the caliper was pushing on the rotor and throwing hot steel shavings everywhere. The hot shavings burned themselves into the aluminum and then rusted...
If you hear a noise, fix it... people like to think things are OK all the time.
