Abstract
The invention relates to spring (40) for a disc brake. The spring is mounted elastically in an opening (68) of a caliper and exerts on the support plates (26, 28) a radial force (F1) as well as a tangential force (F'5) ensuring that the plates assume a preferred lateral position. The spring (40) comprises a metal leaf with two main arms (42, 44) connected to each other and to a central arm (48) by a main fold (46), the spring having the general shape of a "trident", the end prongs of which comprise the main arms (42, 44), the latter cooperating by way of their free ends (50) with a surface (52) formed on the caliper (10) and by way of central portions (54) with bearing surfaces (56) formed on the support plates, the central arm (48) having at its free end (62) a Z-shaped fold cooperating with two surfaces (64, 66) of the caliper, the main fold (46) having a lug (74) cooperating radially with another surface (76) of the caliper (10).
