intervals of 120°.
Measure the brake disc thickness at these three points.
Example shows third measuring point
The minimum permissible thickness of the brake disc is engraved
as "min.th." on the brake disc hub.
– Measure the thickness -x- of the brake disc at the measuring
points all around the brake disc (three times).
If the thickness of the brake disc is below the "min.th." value at
