3.5.1 Checking brake disc thickness
The markings for measuring the degree of wear are spaced at
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
one of the measuring points, the brake disc must be renewed.
Example of minimum brake disc thickness (min.th. -3-); the brake
disc thickness must not be less than this value.
Note
Value -3- may vary depending on the brake disc.
WARNING
If one brake disc is damaged or worn, the other discs must also
be checked for damage and wear.
If the thickness of the brake disc is not below the minimum value,
