A brake disk characterized in that it comprises two half-disks (1, 2), each having a friction surface able to interact with a brake pad and directly linked to each other by brazing on a face opposite to said friction surface. The half-disks have edge profiles and holes offset between the two half-disks, so as to create closed cavities on the faces exposed to the brake pad. A method for obtaining a brake disk as described above.
