Abstract
The center loop anti-rattle spring (50) comprises a pad biasing plate (52) which biases disc brake pads radially inwardly to prevent rattling. The pad biasing plate (52) has at one axial edge (55) a loop arm (56) which extends around approximately 270.degree. in order to position an axially extending axial arm (58) orthogonally relative to the pad biasing plate (52). The axial arm (58) extends into circumferentially extending ear members (62) each having an opening (64) for receiving a pin (60) which connects the spring (50) to a torque support member (18). Each ear member (62) extends into a radial retention tab (66) which extends axially under an arm end (22) of the torque support member (18). The pad biasing plate (52) has oppositely disposed corner recessed areas (54) for reception of the radial retention tabs (66). The axial arm (58) includes a center notch (63) for receiving a base portion (57) of the loop arm (56) during manufacture of the spring.
