Claim 0:
1. A disk brake for a motor vehicle, comprising:
an internally ventilated brake disk having a friction ring with an external friction surface on each one of two friction ring halves connected by ribs which are located therebetween, the ribs forming cooling channels between the friction ring halves;
a brake disk nave, which is connected to the friction ring via radially directed connecting means and has on its casing a collar, which extends in the radial direction and forms a fit to an external diameter of the friction ring by way of an outer circumferential surface and to an internal diameter of the friction ring by way of an inner circumferential surface; and
radially directed first bores, in which the connecting means are introduced such that they extend further into radially directed second bores in the friction ring, wherein
the brake disk nave forms the fit with a single friction ring half and this fit has material convexities, which point inward toward the cooling channels or the ribs, at the points at which the second bores are introduced for the connecting means.
