Abstract

A brake rotor and a method for manufacturing the same are provided. The brake rotor includes first and second spaced apart annular plates, a plurality of radially disposed ribs extending therebetween and at least one heat sink having fins located between the plates for dissipating heat from the rotor. The plates may be formed separately from one another in a casting process. In one embodiment, the plates and ribs are foil led of cast iron and the ribs protrude from the inner surfaces of the plates. The ribs of one plate generally correspond to the ribs of the other plate so that the ribs mate up when the plates are assembled. Heat sinks, which may be machined from aluminum, each include a base having relatively thin fins extending therefrom. The heat sinks are assembled between the plates and in contact with inner surfaces of the plates.
