ABSTRACT:
The present invention relates to an improvement on a floating spot type disc brake in which the caliper slides in the disc axial direction. The brake has a U-shaped arm of the torque member that extends to the outer circumferential part of the disc from one side of the rotatable disc which is to be braked. Bush boots of an elastic material are provided between the penetrating holes provided in the disc axial direction in the U-shaped arms of the torque member which is fixed to a non-rotating part and the slide pin parts provided on the other hand in the caliper member which straddles over the outer circumference of the disc and is slidable in the disc axial direction. A bush dust boot which is capable of freely expanding and contracting in the axial direction is provided at the root of this bush boot attached to the caliper member and a small aperture is provided at the other end to enable air to come in and go out when the slide pin moves in this boot while preventing the entry of foreign bodies from outside. Pad retainers which engage elastically with the torque member, caliper member and friction pads contained in the torque member is provided.
