A disc brake rotor apparatus includes an annular inner member for mounting to a hub, an annular outer member concentric with the annular inner member and having opposite braking surfaces, a first intermediate member extending radially outwardly from the annular inner member to the annular outer member, and a second intermediate member extending radially outwardly from the annular inner member to the annular outer member. The first intermediate member is at least partially and axially spaced apart from the second intermediate member and forms a chamber therebetween.
