Abstract
The invention is directed to a method of forming a vented rotor for caliper disc brakes and the like. Such a vented rotor includes an outer friction portion having one or more ring sections with opposed friction surfaces adapted to interface with associated friction members. The vented rotor is formed by first casting a rotor to the desired configuration including at least the ring section. This initial casting is formed in such a manner that one or more depressions are provided a surface of the ring section. Then, material is removed in one or more machining steps from portions of the friction surface opposite the friction surface having the depressions, to the point that the depressions extend completely through the ring section to form the vents.
