Abstract: An anti-rattle spring (11) is mounted in a backing plate (31) of one a pair of opposed backing plate and friction pad assemblies (15) in a generally planar parallel relationship with a rotor (17) engaging friction surfaces and stationary torque support members (19, 37). The spring (11) comprises a base portion (21) disposed in a plane which is generally parallel to the planes of the friction surfaces. The base portion (21) is fastened to one of the pads (15) through an elongated boss (39) in backing plate (31) and a corresponding hole (45) in the backing plate (31). The relationship between the elongated hole (45) and boss (39) prevents the anti-rattle spring (11) from rotating on the backing plate (31). The spring (11) also includes a web portion (23) which extends generally perpendicularly from the base portion (21) and a U-shaped resilient cantilevered blade (25) which extends from the web portion (23). The curved blade (25) has a free end (27) which engages the torque support member (19) to provide a resilient biasing between the torque support member (19) and the pad (15). The curved resilient cantilevered blade (25) extends initially from the web portion (23) in a direction away from the torque support member (19) and is subsequently curved back toward and into engagement with the torque support member (19). There is also a relatively flat resilient cantilevered blade (29) extending generally orthogonally from the base portion (21) in a direction opposite the web portion (23). This blade (29) will engage the brake rotor (17) during brake operation only if the thickness of the friction material of the outer brake assembly (15) is less than a predetermined thickness, thus providing an audible wear-limit warning.
