A floating-caliper disc brake of a motor vehicle has a component fixed to the vehicle, in particular a brake support member, and a floating caliper ( 2 ) that is displaceably mounted on the component fixed to the vehicle by way of at least two pin guides ( 10, 20 ). A first pin guide ( 10 ) includes a carrier pin ( 11 ), among others, for the transmission of brake circumferential forces. A second pin guide pin ( 20 ) includes a guide pin ( 21, 21', 41 ) for positioning the floating caliper ( 2 ) perpendicular to its direction of displacement. To improve the floating-caliper guide, among others when high brake circumferential forces prevail, it the second pin guide ( 20 ) constitutes a multipart guide pin ( 21, 21', 41 ), with a pin ( 22, 22', 42 ), an elastic sleeve ( 23, 45, 50, 55 ) encompassing the pin ( 22, 22', 42 ), and with a sliding bushing ( 28, 28', 38 ) encompassing the elastic sleeve ( 23, 45, 50, 55 ).
