Abstract
A device can indicate the total load of a brake disk made of carbon-fiber-reinforced ceramic material. In order to create such a device, which can be used for brake disks and other friction elements made of carbon-fiber-reinforced ceramic material, an indicator element can be provided in the brake disk starting from the friction surface. The oxidation stability of this indicator element is reduced with respect to the material of the brake disk.
