3.5.4 Notes on ceramic brake disc wear limit
Note
♦ The degree of wear is determined by measuring the brake disc
thickness AND the wear value using the tester - VAS 6813- ;
both values must be measured three times each.
♦ The brake disc hub is engraved with the minimum permissible
thickness of the brake disc (“min.th.”) and the wear value -C-
for the tester - VAS 6813- .
♦ The wear value -C- varies depending on the brake disc and
the measuring point.
Note
♦ If the thickness of the brake disc is below the “min.th.” value
at one of the measuring points, the brake disc must be re‐
newed.
♦ “Or”
♦ If the value is less than or equal to one of the three wear values
-C- when determining the degree of wear with the tester - VAS
6813- , the brake disc must be renewed.
Note
The wear value -C- varies 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.
