ABSTRACT:
A brake rotor assembly for a dual brake disc braking system includes an annular ring having a plurality of teeth. The teeth are disposed radially about a central axis of the annular ring, and extend inward toward the central axis. The teeth are for slideably engaging a hub (wheel end) having a plurality of channels. The annular ring includes a plurality of pins extending outwardly from the annular ring. A friction disc is disposed radially about the annular ring, and is in interlocking engagement with the plurality of pins. The annular ring and the plurality of teeth are integrally cast from a high strength corrosion resistant material having a tensile strength greater than 260 megapascals to resist fracture during high stress braking conditions and high thermal loads. The friction disc is cast around the annular ring from a grey cast iron.
