ABSTRACT:
The disc brake (10) comprises a support member (12) having horizontal (11C) and vertical (11A) surfaces intersecting at chamfered corner surfaces (11B) forming torque receiving portions (11B). The caliper (20) of the disc brake (10) has a top central opening (13) comprising sloped side walls (15) intersecting with sloped top inner walls (17) of the caliper (20). Friction pad backing plates (26, 28) include circumferentially spaced apart lateral projections (21) each having a chamfered corner surface (2B) which engages the corresponding chamfered corner surface (11B) of the support member (12), and a radially outwardly extending extension (27) having a V-shaped groove (29) engaged by a unitary leaf pad spring (40). The unitary leaf pad spring (40) comprises a generally H-shaped spring (40) having a central body portion (41) forming a depending longitudinal rib (41) and a pair of opposite outwardly extending multiple bend change-of-direction arms (42) at each end of the central body portion (41), each arm (42) terminating in a radially outwardly extending finger terminal end (43). The terminal ends (43) of the spring (40) engage the sloped top inner walls (17) of the caliper (20) and the depending longitudinal rib (41) engages the grooves (29) of the extensions (27) to bias the chamfered corner surfaces (2B) of the lateral projections (21) into engagement with the torque receiving portions (11B) of the support member (12).
