AbstractA pair of arms have opposite bearing portions between which disc-passing regions are defined. Each of the disc-passing regions has a centerline offset outwardly from the centerline of a disc. A pair of pad springs have respective engagement regions engaged with the disc-passing regions. By this arrangement, a pair of inboard and outboard return springs are laterally symmetrical with respect to the centerline of the disc-passing region or pad spring. The return springs are deformed to cause their free ends or bias portions to be resiliently contacted with the inner surface of bent portions of wear warning elements. This enables the amount of deformation of the outboard return springs to be greater than the amount of deformation of the inboard return springs. Thus, the outboard return springs exert a force greater than that of the inboard return springs.
