    Maximum disc runout:
    0.05 mm (0.00197 in.)
    If the runout is greater than the maximum, change the installation positions of the disc and axle so that the runout will become minimal.
    If the runout is greater than the maximum even when the installation positions are changed, grind the disc. If the disc thickness is less than the minimum, replace the disc.
