ABSTRACT:
An improved mechanical disc brake, of the type in which a rotational operating force applied to a nut member adjustably carrying a push rod is converted into linear axial movement of the nut member and push rod to cause the push rod to move a brake pad engaged thereby into braking engagement with the disc, is provided in which the nut member is floatingly mounted on the housing of the brake for minimizing the wear and other adverse effects of natural vibration of the housing, and in which there is a device for urging the nut member into a self-centering position for maintaining the push rod in optimum relationship with the associated brake pad. The improved brake construction also facilitates provision for proper dust covers, lessens the precision required in the manufacture of certain parts, and permits proper adjustment of the brake to be accomplished even after replacement of the brake pads. The improved construction employs an opposed groove and ball mounting of a flange portion of the nut member upon the associated leg portion of the housing and a spring device for biasing the position of the nut member relative to such leg portion of the housing, with there being no direct engagement between the nut member and such leg portion of the housing.
