Maximum disc runout: 0.05 mm (0.0020 in.)
(c)If the disc's runout is maximum value or greater, check the
bearing play in the axial direction and check for the axle
hub runout (See page 30±2). If the bearing play and axle
hub runout are normal, adjust the disc runout or grind it
on a ºOn±carº brake lathe.
