ABSTRACT:
A disc brake that is less likely to squeak during braking. A guide portion on a torque member has a point at which the force counteracting the braking force is produced. This point is disposed nearer to a line pass through the center of the disc than is a parallel line passing the center of the brake cylinder and extending tangentially to a circle concentric with the disc. Thus, due to the tangential force produced during braking, angular moment is produced in the same direction as the angular moment produced due to the braking force. The sum of these two angular moments act to restrain the rotation of the pads. The movement of the pads are thus strongly restrained, so that they are less likely to vibrate. Thus, it is possible to prevent squeaking of the brake resulting from vibrations of the pads.
