Claim 14:
15. A method for producing a brake disk comprising:
producing corresponding fitting surfaces on the external diameter of a collar of a brake disk nave and on an internal diameter of a friction ring half which, as seen in the axial direction of a brake disk, is located closer to a nave base of the brake disk nave;
pressing the brake disk nave into the friction ring half in the axial direction of the brake disk, with the nave base in front, from the side of the friction ring with the friction ring half which does not have a fit;
ending the pressing of the brake disk nave into the friction ring half when shape parity is reached between the inner side of the friction ring half which has the fit to the brake disc nave, and the brake disk nave collar, as seen in the axial direction of the brake disk, on the inner side of the friction ring half, which has the fit to the brake disc nave;
boring first and second bores, at least in a respective work step, per bore pair composed of one first and one second bore, and boring the cooling-air outlet channel; and
introducing a respective connecting means into each bore pair.
