Abstract:
A rotor adapted for use in a vehicle disc brake assembly includes an inner annular mounting flange portion defining a rotational axis and an outer annular disc portion. The outer annular disc portion includes a pair of friction plates which are connected together in spaced apart relationship by a plurality of posts located about the circumference of the rotor. The plurality of posts are divided into a plurality of groups of four posts. Each group of four posts includes a first post and a second post which are radially aligned with one another along with respect to a first bisecting radius extending outwardly from the rotational axis of the rotor. Each group of four posts also includes a third post and a fourth post which are radially aligned with one another with respect to a second bisecting radius extending outwardly from the rotational axis of the rotor. The first common bisecting radius and the second common bisecting radius are disposed at a predetermined angle relative to one another. The first, second, and third posts are formed having a tear-drop cross sectional shape, while the fourth post is formed having a circular cross sectional shape.
