The method of claim 1, wherein supporting an insert comprises supporting the insert with a plurality of spacers each constructed from cast iron, and wherein introducing a molten material comprises introducing molten cast iron into the mold cavity. 3. The method of claim 1, wherein supporting an insert comprises supporting the insert with a plurality of spacers that are imbedded in the casting die. 4. The method of claim 1, wherein the mold cavity is shaped to form a brake component. 5. The method of claim 4, wherein the mold cavity shaped to form a disc brake rotor. 6. The method of claim 1, wherein the casting die is constructed from packed sand. 7. The method of claim 1, further comprising solidifying the molten material in the mold cavity and around the insert. 8. The method of claim 1 further comprising solidifying the molten material to provide a product and wherein the insert has a coating thereon to protect the insert from interacting with the molten material and so that the insert friction damps the product. 9. The method of claim 1 wherein the insert is annular shaped or comprises a plurality of arch shaped segments. 10. The method as set forth in claim 1 wherein the spacers have at least one of a spike of I shape. 11. The method as set forth in claim 1 wherein the mold cavity is defined by an upper die member and a lower die member, wherein the upper die member and the lower die member also define the rotor cheek of a disc rotor, and wherein the insert, spacers and the upper die member and the lower die member are constructed and arranged so that the insert is approximately equidistant from a portion of the upper die member and the lower die member defining the rotor cheek. 12. A method comprising: providing a casting die having a mold cavity shaped for casting a brake component, wherein the casting die includes an upper die member and a lower die member each constructed from packed sand and that, when closed, define the mold cavity, and one or more spacers of a first composition imbedded in either of the upper die member or the lower die member of the casting die;providing at least one insert the at least one insert individually having an arcurate shape and size that substantially coincides with annular and radial dimensions of the mold cavity and being annularly aligned and axially spaced in an end-to-end relationship within the mold cavity;thereafter supporting the at least one insert in the mold cavity with one or more spacers of a first composition; andcasting a brake component in the mold cavity around the at least one insert using a molten material of the first composition. 13. The method of claim 12, wherein the casting a brake component in the mold cavity around the at least one insert using a molten material of the first composition is conducted so that the one or more spacers are melted and consumed by the molten material. 14. The method of claim 13, wherein the casting a brake component in the mold cavity around the at least one insert using a molten material of the first composition is conducted so that the insert is at least partially encased by the molten material. 15. The method of claim 12, wherein the one or more spacers of a first composition comprise a plurality of spacers each constructed from cast iron. 16. The method of claim 12, wherein the mold cavity is shaped to define a disc brake rotor. 17. The method of claim 12, wherein the casting results in the one or more spacers of a first composition being melted and consumed by the molten material of the first composition. 18. The method of claim 12 wherein the insert has a coating thereon to protect the insert from interacting with the molten material and so that the insert friction damps the brake rotor component. 19. The method as set forth in claim 12 wherein the mold cavity is shaped to define a disc brake rotor, wherein the casting results in the one or more spacers of a first composition being melted and consumed by the molten material of the first composition, and wherein the insert is annular shaped or comprises a plurality of arch shaped segments. 20. The method as set forth in claim 19 wherein the spacers have at least one of a spike of I shape. 21.
