Bolt Guide Device for a Floating Caliper Disc Brake and Corresponding Floating Caliper Disc Brake

A floating caliper disc brake having at least one guide bolt that is mounted on a brake caliper and movably guided relative to a brake carrier in axial direction of the guide bolt, wherein the floating caliper disc brake is configured with a bolt guiding device, wherein the bolt guiding device is disposed between an inner circumferential surface of a location hole of the brake carrier and an outer circumferential surface of the guide bolt accommodated therein, wherein 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,

• wherein the slide bush has, facing the sliding surface:
• at least one guiding surface on each side of a centre of the slide bush and at least one intermediate surface extending in the circumferential direction on each side of the centre of the slide bush,
• wherein a diameter of the guiding surfaces is dimensioned in such a way that the guiding surface is in close contact with the sliding surface, and
• wherein a diameter of the intermediate surfaces is dimensioned in such a way that the intermediate surface is provided in direct contact with or with a slight radial spacing from the sliding surface, and wherein the intermediate surfaces are configured to come into supportive action with the sliding surface in the event of a deformation of the guiding surfaces.
