2121119 9309360 PCTABS00022 The disc brake (100) with variable width caliper comprises first and second bridge members (14, 15) which are connected with a pair of movable members (20, 30) extending over the periphery of the rotor (51). Each of the movable members (20, 30) is mounted upon an anchor extension (37A, 38A). An inboard end of each movable member (20, 30) includes threads (26, 36) upon which is threadably mounted a nut (28, 29). The nut (28, 29) has ratchet teeth (12, 13) on one axial end which engage ratchet teeth (10A, 11A) of an associated actuator sleeve (10, 11) disposed slidably about the movable member (20, 30). The second bridge member (15) is mounted slidably upon the movable members (20, 30). The actuator sleeves (10, 11) may be rotated by an actuator mechanism (70) which, through the engaged ratchet teeth (10A, 11A; 12, 13), causes the nuts (28, 29) to rotate and effect translational movement of the movable members (20, 30). The actuator sleeves (10, 11) engage roller thrust bearings (44, 45) which, as the nuts (28, 29) change their positions along the movable members (20, 30), displace the second bridge member (15) and a friction lining mechanism (16) against the rotor (51), and by reaction, the movable members (20, 30) bring a friction lining mechanism (17) of the first bridge member (14) into engagement with the other face of the rotor (51). The second bridge member (15) may include one or more bores (50) each receiving therein a piston (52) and actuatable by hydraulic fluid.
