  • Patent number: 5172792
    Abstract: The disc brake (10, 210) comprises a support member (12, 212) having circumferentially spaced apart pin support portions (16, 18; 216, 218) with pin openings (20, 24). A cordal type carrier having inboard (32, 232), outboard (34, 234), and circumferentially spaced apart sides (36, 236; 38, 238) is mounted slidably by pins (22, 28; 222, 228) on the support member (12, 212). The pins extend slidably through the pin openings (20, 24) and are each fixed to the carrier (30, 230). One (22, 222) of the pins (22, 28; 222, 228) has a larger diameter than the other (28, 228) of the pins (22, 28; 222, 228), and the smaller diameter pin (28) has disposed thereabout an axially extending and slidable sleeve member (26).

  • Patent number: 4969540
    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.
