A brake rotor adapted for use in a vehicle brake system includes a brake rotor formed by a casting process. The brake rotor includes an inner mounting flange and an outer friction disc. The inner mounting flange includes an inner surface, an outer surface, and a center pilot hole formed therethrough. The outer friction disc includes an inner friction plate and an outer friction plate. The inner friction plate has an outer facing surface, an outer peripheral edge and an inner peripheral edge. The outer friction plate has an outer facing surface and an outer peripheral edge. The outer friction plate is connected to the inner mounting flange by a hat, and the hat has an outer facing surface and an inner facing surface. The inner mounting flange of the brake rotor includes a plurality of lug bolt receiving holes formed therethrough which are formed during the casting process.
