Abstract
The invention provides a disc brake in which a tongue on a yoke is securely received in a blind bore formed in a piston of a hydraulic actuator by means of a pair of insert members of a resilient material. The insert members have grooves, respectively, for receiving the tongue. Each insert member has a part-cylindrical surface and the undistorted radius of curvature of the part-cylindrical surface of each insert member is greater than the radius of curvature of a cylindrical wall of the blind bore to permit easy insertion, during assembly, of the pair of insert members into the blind bore. When the tongue is inserted into the grooves of the insert members disposed in the blind bore, the part-cylindrical surfaces of the insert members are urged into firm engagement with the cylindrical wall and the insert members are caused to be distorted in such a manner as to urge the side walls of the grooves into firm engagement with the tongue.
