Abstract: A mounting arrangement for use in a floating-caliper spot-type disc brake including a carrier component and a caliper component, for mounting on one of the components a guide bolt which is slidably received in a bore of the other component, includes a recess in the one component for partially receiving the bolt, this recess being open, over its entire axial length, onto the periphery of the one component to provide a free path for the movement of the bolt into and out of the recess. The bolt and the one component have cooperating abutment surfaces either within or outside the recess, which prevent the bolt from turning about its longitudinal axis once properly received in the recess. The abutment surface of the bolt may be provided either on a key-bit-shaped or on a cross-sectionally polygonal, especially square, portion of the bolt.
