Brake discs do not need to be replaced!
Friction surfaces after a long journey and occasional high load. Isolated cases of connected surface fractures less than 1 cm²-arrow-

PCCB surface fractures

No replacement necessary as the connected surface fractures are < 1 cm² !
End of service life of friction surface or after highest load on a racing circuit.
Replace brake discs if the connected friction surface damage is > 1 cm²-arrow- . To do this, follow the instructions provided under

> 465102 Checking front PCCB brake disc (wear assessment) - section on "INFORMATION "

PCCB friction surface damage

The best way to detect a surface fracture is by checking the wear indicators. Based on the wear indicators, this means that at least one wear indicator -arrow- must have a surface fracture of > 50% (damage > 1 cm² /entire surface of a wear indicator with a surface area of approx. 2 cm² ).
