ABSTRACT:
A disc rotor for a disc brake which is designed to make it difficult to cause brake squeal includes inner and outer discs, and first and second radially extending long holes formed in the outer and inner discs. The angular intervals between the long holes are made to differ between the outer disc and the inner disc, and two vibration modes are produced to interfere with each other during braking operation by which the occurrence of a steady-state vibration mode is restrained. In addition fins are provided between the two discs, with the fins including several fins arranged to reinforce both the inner and outer discs.
