The invention relates to a method for producing a brake disk (B) that comprises a supporting part ( 2 ) and a friction ring (R). The inventive method involves the following working steps: manufacturing, especially by casting, the supporting part ( 2 ) with at least one radially protruding projection ( 10 ) situated on the periphery of the supporting part; forming a cast core ( 14 ), which is made of core sand and which surrounds the projection ( 10 ) over a foot section ( 10 a) that is assigned to the supporting part ( 2 ), onto the supporting part ( 2 ) while sealing a free end section ( 10 b) of the projection ( 10 ) so that this end section ( 10 b) is not made wet by the sand of the cast core ( 14 ); casting the friction ring (R) onto the supporting part ( 2 ), which is provided with the cast core ( 14 ), while casting around the free end section ( 10 b) of the projection ( 10 ). The inventive method enables the production of brake disks, which are additionally optimized with regard to their function, with a supporting part and friction ring that are cast at different times. The invention also relates to a core forming tool, which is particularly suited for carrying out the inventive method.
