Abstract

A method for manufacturing a brake rotor which includes a disc-shaped carrier and friction rings arranged on or on top of the carrier, so that the friction rings and carrier form a single piece construction. The carrier and friction ring(s) are separately molded into pre-forms, subsequently joined and finished formed in a press tool. The carrier and friction rings are made from carbon/carbon materials and ceramic materials respectively. The carrier has a hat-shaped cross-sectional shape with a flanged outer edge and the friction rings are attached to each side of the flanged edge of the carrier. The brake rotor may be directly mounted onto the wheel flange via the carrier using bolts.
