  1. Place a dial gauge about 10 mm (0.2 in.) from the outer circumference of the brake disc, and measure the runout of the disc.

  2. If the runout of the brake disc exceeds the limit specification, replace the disc, and then measure the runout again.
  3. If the runout does not meet the limit specification, remove the disc, turn it 180° and reinstall. Then check the runout of the brake disc again.
  4. If the runout cannot be corrected by changing the position of the brake disc, replace the brake disc.
