Disk brake construction

Claim 1

In a disk brake, particularly for automotive vehicles, a combination comprising a rotor disk mounted for rotation about a predetermined axis; a mounting element straddling a section of the periphery of said rotor disk and having at opposite sides of the same a pair of substantially U-shaped cutouts aligned axially of said rotor disk and each extending in direction inwardly of said periphery, said cutouts each having a bottom face provided with a notch extending in direction of said axis and opposite side faces at opposite sides of said axis; a presser element for friction pads also straddling said section and having portions located at opposite axial sides of said rotor disk and each extending into one of said cutouts and having a projection received in the respective notch; yieldable retaining means yieldably retaining said presser element with freedom of displacement both axially and radially outwardly relative to said rotor disk; cooperating slide surfaces on said portions and on said side faces, respectively, for enabling sliding displacement of said presser element axially of said rotor disk; and anticontaminant means for preventing the entry of contaminants between the respective slide surfaces, including strip members of elastically yieldable material interposed between the respective guide members and the associated side faces and each having at least one compressible bead elongated in direction of said axis and sealingly engaging said mounting element and said presser element along the edges of said slide surfaces in any relative position of said elements.
