In a brake disc (1) having at least one friction surface (2), on the edge of which there is at least one recess (10) with a bottom, wherein the bottom indicates the wear limit of the brake disc, a check can be carried out particularly simply as to whether the residual thickness of the brake disc is sufficient if the recess is arranged in such a way that part (12a) of the edge (12) of the recess is swept over by at least one brake pad during braking and another part (12b) of the edge of the recess is not swept over. |
