The disc consists of a core (1), being a hub (3) surrounded by spokes (2), and friction pads in the form of annular sectors (8) having recesses (15, 16) in their inside backs (10) to cooperate with the spokes (2) in providing radial guidance and angular locking. Elastic means are provided for removably axially mounting the sectors on the core (1), which elastic means (19, 6) also serve to removably radially mount the sectors on the core.

A disc brake disk comprising a core designed to withstand mechanical stresses, said core including a hub, a plurality of spokes surrounding said hub and hooks at the end of said spokes, each of said spokes having two opposite flat faces and two opposite edges, removable friction pads fitted on both sides of said core, each of said friction pads including a plurality of annular sectors, each sector having an axially outside friction surface and an axially inside mounting surface with lands and recesses, each sector having a radially outer edge with an oblique surface and a radially inner edge with an oblique surface, said hooks cooperating with the oblique surfaces of the outer edges of said sectors to form stops against both axial and radial movement of said sectors, said lands of said sectors on each side of said core bearing axially against one another back to back, each sector covering two angular spaces between spokes by overlapping one middle spoke and halves of two side spokes, said lands and recesses comprising a radial center slot having a bottom and edge walls and two radial half-width slots in the ends of the sector, said edge walls cooperating with said edges of said middle spoke for radial guidance and annular locking of the sector, a clearance being left between said bottom and said flat surface of said middle spoke, said half-width slots leaving room with clearance for said side spokes, the sectors on one side of the core being offset circumferentially relative to the sectors on the opposite side of the core by a half-sectors breadth and spring rings attached to the hub pushing elastically against corresponding oblique surfaces of the inner edges of the sectors so as removably to mount the sectors on the core.
