Abstract:
1. An arrangement for a disc brake, the arrangement comprising: a guide bar of the disc brake, the guide bar having an encircling groove; a bellows arranged on the guide bar, the bellows having an end with a sealing ring, the sealing ring being configured to seal against air flow between the sealing ring and the guide bar in the absence of a higher pressure in a volume of space enclosed by the bellows than in a region outside the bellows; a retaining ring operatively arranged to press the sealing ring of the bellows radially into the encircling groove of the guide bar; wherein the sealing ring, groove and retaining ring are operatively configured such that an inner circumference of the sealing ring seals against an entire radially inner base of the encircling groove when the sealing ring is in a rest position, and in an event of an operationally induced reduction in volume of the space enclosed by the bellows and the guide bar, an air passage is formed in at least a portion of a contact region of the inner circumference of the sealing ring against the radially inner base of the encircling groove.
