Abstract
A bellows arrangement on a guide bar of a disc brake, particularly of a commercial vehicle, has an end of the bellows comprising a sealing ring, particularly a quad ring, lying in a circumferential groove of the guide bar. The bellows is pressed into the groove by a retaining ring placed thereon, and is designed so that an air passage can form in the contact area of the sealing ring at the base of the groove, reducing the volume enclosed by the bellows and the guide bar. To this end, the contact shoulder formed on the retaining ring is circumferentially interrupted in segments.
