摘要

A brake disk includes a disk body with an inner ring portion adapted to be coupled to a wheel hub, an outer ring portion disposed around the inner ring portion and adapted to be in frictional contact with a brake pad, and a plurality of connecting ribs extending between and interconnecting the inner and outer ring portions. Each of the connecting ribs has a reinforcing portion which projects relative to one of two opposite side surfaces of the disk body.
