ABSTRACT:
The brake piston adjuster mechanism includes an expandable or deformable tube (80) which is attached to the piston (60) and engaged by a deforming member comprising a pin (190) having a threaded end (194) receiving thereon a nut (193) and tube expander (192). The nut (193) biases the tube expander (192) against a chamfered pin shoulder (191). The tube expander (192) has at least one inner diameter chamfer (198) which engages the chamfered pin shoulder (191) in order to impose preload forces upon the chamfered pin shoulder (191) and reduce stresses at a smaller diameter portion (195) of the pin. The (193) nut may be a castellated nut (193) which receives a locking wire or pin (200) extending through an opening (199) in the threaded end (194) of the pin (190). Alternatively, the tube expander and nut may comprise a one-piece expander nut (293, 393, 493) having an enlarged radially extending end poriton (294, 394, 494 ) and the nut (293, 393, 493), when advanced along the threads of the pin (190), causes a chamfer (298, 398, 498) of the end portion (294, 394, 494) to advance along the chamfered pin shoulder (191) and cause the end portion (294, 394, 494) to deform elastically, improving the preload retention of the connection.
