My daughter has a 2000 Camry, V6. She has been experiencing a lot of pulsation when braking. I decided to change her front brake rotors. No problem removing the calipers or the torque plate that the caliper attaches to, but then the problems began. It seems that the rotor has rusted around the cenetr hole and probably on the back side. I have tried banging on the rotor with a hammer, but that didn't seem to work. Maybe I just need a bigger hammer. Anyway, any help here would be greatly appreciated.
