The light-weight brake pedal assembly is composed of a metal framework and a plastic shell wrapping the outer portion of the metal framework, and the plastic shell and the metal framework are integrally formed in an injection molding mode through inserts; rhombic net-shaped reinforcing ribs are arranged on the front half section of the back surface of the plastic shell; the back surface of the plastic shell is provided with two cylindrical positioning holes in tandem; the plastic shell comprises a plastic swing arm body, a pedal piece, a switch limiting piece, a ball cage and a main shaft liner tube. The pedal piece, the switch limiting piece, the ball cage and the main shaft lining pipe are sequentially arranged on the plastic swing arm body from front to back and are integrally formed with the plastic swing arm body in an injection molding mode. The left side and the right side of the connecting position of the pedal piece and the plastic swing arm body are respectively provided with three injection molding reinforcing ribs in the mold drawing direction. The light-weight brake pedal assembly is few in working procedure, high in size precision, good in appearance and higher in light-weight degree.
