Abstract
A brake disk has an inner annular portion or hub area and an outer annular portion or rub area that are interconnected by a number of spaced arms extending radially and circumferentially between the inner and outer annular portions. The arms can be formed (e.g. stamped) in a number of configurations, whereby the stress on the disk caused by the heat generated in the outer annular portion during braking is relieved by arm deflection, thus preventing warping of the disk. The arms are also configured to distribute stress relatively evenly throughout the arms during expansion and contraction of the outer annular portion, thereby preventing cracks and fractures.
