Abstract
A disc brake rotor has a plurality of radial groves on its opposite sides that are equiangularly spaced. The angular interval of the grooves on one side is different from the angular interval of the grooves on the other side, so that the vibrations of two different modes caused by the grooves on the opposite sides interfere with each other during braking operation. By thus suppressing stationary wave mode vibrations, the disc brake rotor prevents production of brake squeals.
