A disc brake for a motor vehicle, wherein it is possible to displace the actuating piston in the housing both by hydraulic pressure activation of a hydraulic chamber formed in the housing and via a mechanical actuator, wherein the sealing ring is accommodated in an annular groove formed in the housing. Provision is made here for the annular groove to have a groove floor, which runs substantially parallel to the longitudinal axis of the piston, and two groove walls, which adjoin the groove floor, wherein&#x2014;as seen in the direction of the longitudinal axis of the piston&#x2014;a first groove wall is directed away from the hydraulic chamber and a second groove wall is directed towards the hydraulic chamber, wherein the first groove wall merges into the groove floor via a rounded or bevelled transition region at a varying distance from the longitudinal axis of the piston.

A bolt guiding device for a floating caliper disc brake, having at least one guide bolt that is supported in a brake carrier and mounted on a brake caliper, wherein the brake caliper is movably guided over the guide bolt in the axial direction thereof. The bolt guiding device comprises a slide bush, wherein one surface of the inner circumferential surface and outer circumferential surface acts as a retaining surface on which the slide bush is retained, and wherein the other surface of the inner circumferential surface and outer circumferential surface acts as a sliding surface on which the slide bush slides. For this purpose, the slide bush has, facing the sliding surface, at least one guiding surface on each side of the center of the slide bush and at least one intermediate surface extending in the circumferential direction on each side of the center of the slide bush, wherein the diameter of the at least one guiding surface is dimensioned in such a way that said guiding surface is in close contact with the sliding surface, and wherein the diameter of the intermediate surface is dimensioned in such a way that said intermediate surface is provided in direct contact with or with a slight radial spacing from the sliding surface.
