Abstract:
A rotor comprising:a ring shaped first brake pad contact surface and a second brake pad contact surface spaced from the first brake pad contact surface by a plurality of circumferentially disposed vanes, wherein each contact surface is bounded by an inner circumference and an outer circumference and each vane extends in a direction from the inner circumference toward the outer circumference, wherein at least one of the first and the second brake pad contact surfaces includes an array of grooves formed therein; the array of grooves being formed of a circumferentially repeating pattern of groups of groove segments, wherein each group of groove segments includes a plurality of groove segments and each groove segment within a group is radially and circumferentially offset from other groove segments within the group, each groove segment having a length less than the radial distance measured on the surface between the inner circumference and the outer circumference and extending in a direction substantially aligned with an adjacent vane; and an attachment portion secured to at least one of the first and the second brake pad contact surfaces.
