Abstract:
1. A brake rotor comprising: a rotor support; and a braking band disposed on and encircling the rotor support, the braking band having first and second brake pad receiving surfaces on opposite sides of the braking band, with at least one brake pad receiving surface defining a plurality of non-intersecting curvilinear asymmetrical grooves having groove paths extending along the at least one brake pad receiving surface, and groove regions of at least three adjacent, equally sized concentric rings each having inner and outer circumferences with the groove regions arranged circumferentially about a center axis corresponding to the center of rotation of the brake rotor when installed and functioning on a vehicle; wherein the non-intersecting curvilinear asymmetrical grooves are arranged in at least eight groove groups each having at least three grooves, with the grooves of each group radially spaced from each other and with the grooves of each groove group having a different geometry than the grooves of the other groove groups; wherein the three concentric rings correspond to innermost, central and outermost groove region rings, wherein no grooves of the braking band extend from the inner circumference of the innermost groove region ring to the outer circumference of the central groove region ring, and no grooves of the braking band extend from the inner circumference of the central groove region ring to the outer circumference of the outermost groove region ring.
