Claim 14:
15. The method of the claim 1, wherein:
at least one of said blanking steps is a circular crown blanking whereby making said second disc-shaped portion; and/or wherein
at least one of said blanking steps is a circular crown blanking with inner radial extensions whereby making said second disc-shaped portion; said method further comprising
approaching the first disc-shaped portion to said third portion forming said ventilation spacer and approaching said second disc-shaped portion to said ventilation spacer on an opposite side of said ventilation spacer;
connecting by said weld spots said ventilation spacer to said first or second disc-shaped portion whereby making a ventilated braking band;
inserting said inner radial extensions into a cavity of a die; and
providing a step of co-casting a bell which, when solidified, with a peripheral portion thereof embraces at least in part said inner radial extensions to connect said bell to said ventilated braking band allowing a radial thermal expansion movement of the ventilated braking band with respect to said bell.
