So a place put on new front rotors and pads back in august. I started hearing squeaking noises from my brakes so I took the car to a different shop and they said that I needed new rotors. i told them they are new so i took it back to the original shop and they checked it out and they said that the rotors are fine and that I don't need anything. So my question is what are the nominal front rotor measurements for a 2001? I need to know which shop is right so I know if I need to raise hell somewhere or not....
