ABSTRACT:
A disc brake free from dragging torque while being in non-braking state. In this brake, a gap between the friction surface of a rotary disc and the acting surface of an actuator for urging a braking pad assembly onto the disc is made progressively larger into a wedge shape toward the axis of the disc. The torque receiving surface of a torque receiving member is made so slant as to produce a component for moving the pad assembly in a direction away from the axis of the disc in a wedging manner into the gap. The pad assembly is of corresponding shape to the above-mentioned gap and the torque receiving surface. The pad assembly is moved in case of brake application in a direction away from the axis of the disc by virtue of the slantingly shaped torque receiving surface until it comes to abut on a stopper, and it is restored in case of brake releasing in a direction approaching the axis of the disc, due to the action of return springs, with a result of appearing of a preset brake clearance responding to the restoration of the pad assembly in the wedge shaped gap.
