A disc brake which can suppress pad vibration includes an outer pad which while contacting the disc rotor is turned such that the side wall of a guide groove in a support arm on the outer peripheral side abuts with the side face of a projecting section on the outer peripheral side of the pad. A pad support is positioned between the guide groove and the projecting section. The pad support includes a supporting portion, an urging portion and a connecting portion. A projection is provided in the region a little to the bottom of the guide groove on the side face of the projecting section on the outer peripheral side.

Disc brake

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.

Rotor for disc brake

An inner arm for receiving a brake torque applied to an inner pad when a car is running forwardly includes a reinforcing rib, in the portion thereof situated near the opposite side to the side where a torque receiving portion of the inner arm is located. The reinforcing rib projects inwardly from a mounting portion 31A of the inner arm 31A to the slightly upper portion of the torque receive portion 31A of the inner arm 31A in such a manner that the amount of projection of a portion thereof situated near the torque receive portion is greater than the amount of projection of a portion thereof situated near the mounting portion.
