Abstract:
1. A bellows for use on a guide member of a disc brake, the bellows comprising: a plurality of corrugations of the bellows; a circumferential sealing ring at one axial end of the bellows, the circumferential sealing ring being operatively configured to bear sealingly against a surface of an annular groove of the guide member that is located at least one of in and immediately adjacent to, and radially below, a guide surface of the guide member when the sealing ring is in a functional position around the guide member, wherein the guide surface of the guide member is a bearing surface supporting sliding guidance of one component of the disc brake relative to another component of the disc brake; a circumferential sealing lip at an opposite axial end of the bellows operatively configured to bear sealingly against the guide surface of the guide member in a manner that allows axial displacement of the guide surface and the sealing lip relative to one another when the guide member and the bellows are installed in the disc brake; and one or more webs located on a radially inner surface of the bellows and being operatively configured to rigidly connect the sealing lip to an adjacent one of the plurality of corrugations such that upon compression of the bellows after the bellows is in an installed position on the guide member, an air gap is formed at the circumferential sealing lip of the bellows.
