Wear limit technical Data - GT2

Two condition criteria can make replacement necessary depending on the wear of PCCB brake discs:

1. Surface changes in the brake disc friction surfaces at an advanced stage.
2. Brake disc minimum thickness is not attained due to wear (material erosion due to friction).
