Runout check
Establish a magnetic support 1 on the back shock-absorber.
Attach the indicator to the magnetic base.
Place the indicator probe at a distance of 10 mm from the edge of the brake disc.
Make a complete revolution of the brake disc.
Permissible runout of the brake disc mounted on the hub: less than 0.05 mm.
Thickness check
Use a micrometer with 0/50 mm increments.
Maximum difference in thickness in one plane: 0.01 mm.
