ABSTRACT:
A generally annular rotor insert is formed by casting a metal matrix composite. The rotor insert includes a pair of brake friction plates which are disposed in mutually spaced apart relationship. The brake friction plates include inner surfaces and generally parallel outer surfaces. At least one of the inner surfaces of the brake friction plates is provided with a plurality of spacing elements for engagement with the inner surface of the other one of the brake friction plates for maintaining the plates in predetermined spaced apart relationship. The rotor insert is placed in a rotor mold. A hat-shaped rotor body is cast in the rotor mold whereby the spacing elements are effective to maintain the plates in a predetermined spaced apart relationship.
