NOTICE: Using an impact tool without a torque socket will lead to unevenly tightened wheel nuts. This causes brake disc on-vehicle lateral runout and brake roughness.
1. Inspect the brake discs and measure the brake disc thickness. Record the measurement. Refer to Specifications.
- If the brake disc is cracked or otherwise damaged, install a new brake disc.
- If the measurement is below the minimum thickness specification, install a new brake disc.
- If the diagnosis has revealed vibration in the steering wheel, seat or pedal while braking that varies with vehicle speed, machine the brake disc. Heavily scored brake discs, similar to that caused by pads worn down to the backing plate, should also be machined. In order to machine, discs must be above the minimum thickness specification. For additional information, refer to Specifications and Brake Disc Machining .
