A few warm tips on minimizing the noises made by disc brakes: 1. If you have ridden fewer than 300 km on your bike the brakes are not yet fully ridden in. In this case it is very probable that the noises will go away themselves if you ride more. 2. A common cause for squeaking disc brakes are dirty brake rotors. To clean them take the wheels out and clean the rotors thoroughly with water or a special cleaner from a good bike shop. 3. Check if all bolts and screws connecting the hub body to the brake rotor are correctly tightened.
