Chevrolet Sonic Repair Manual: Brake Rotor/Drum Balance Inspection
- Support the vehicle drive axle on a suitable hoist. Refer to Lifting and Jacking the Vehicle.
- Remove the tire and wheel assemblies from the drive axle. Refer to Tire and Wheel Removal and Installation.
- Reinstall the wheel nuts in order to retain the brake rotors.
- Run the vehicle at the concern speed while inspecting for the presence of the vibration.
- If the vibration is still present, remove the rotors from the drive axle, then run the vehicle back to the concern speed.
- If the vibration is eliminated when the brake rotors are removed from the drive axle, repeat the test with one rotor installed at a time. Replace the rotor that is causing or contributing to the vibration concern.
- If a brake rotor was replaced as a result of following the previous steps, or if necessary to confirm the results obtained during the previous steps, and/or to check the non-drive axle components, perform the following:
- Mount the brake rotor/drum on a balancer in the same manner as a tire and wheel assembly.
- Inspect the rotor/drum for static imbalance.
Warning:
Refer to Work Stall Test Warning.
Caution:
Do not depress the brake pedal with the brake rotors and/or the brake drums removed, or with the brake calipers repositioned away from the brake rotors, or damage to the brake system may result.
Note:
Check brake rotors/drums for static imbalance only; ignore the dynamic imbalance readings.
There is not a set tolerance for brake rotor/drum static imbalance. However, any brake rotor/drum measured in this same manner which is over 21 g (¾ oz) may have the potential to cause or contribute to a vibration. Rotors/drums suspected of causing or contributing to a vibration should be replaced. Any rotor/drum that is replaced should be checked for imbalance in the same manner.
