A disk brake comprising a disk (1) which carries on each side a secondary friction layer (7) to which a primary friction layer (6) is affixed, wherein the friction layers (6, 7) are actuable by force-exerting means (4, 5), wherein when at least one of the primary friction layers (6) is worn away contact between the secondary friction layer (7) and respective force-exerting means (4, 5) will give rise to an indicating sound, and wherein cooling grooves (9) are provided in the primary friction layer (6), wherein each cooling groove (9) extends at least through the full thickness of the primary friction layer (6). <IMAGE> |
