DISC BRAKE FOR A COMMERCIAL VEHICLE

The invention relates to a disc brake for a commercial vehicle, comprising a brake caliper (2) which comprises a brake disc and which is fixed to a stationary brake support (1) by means of two fixing elements in an axially movable manner relative to the brake disc. Each of the fixing elements has a guiding bar (9) which is rigidly connected to the brake support (1), one of said guiding bars being guided in a sliding bearing in the form of a fixed bearing and the other being guided in a sliding bearing in the form of a floating bearing for the axial displacement of the brake caliper (2). At least the floating bearing has a guide bush (7) which surrounds the guiding bar (9), is held in a caliper bore (21) of the brake caliper (2) so as to prevent displacement, and comprises an elastic inner sleeve (11). The disc brake is designed such that a first rolling bellows (12) is arranged at least on the guiding bar (9) end region facing away from the brake disc, said rolling bellows sealing the end region from the surroundings, and the rolling bellows is fixed to the guiding bar (9) and in the guide bush (7).
