<p>A caliper slide pin 19 is carried in an axially extending bore 21 in a boss 24 of a torque plate 30 and is secured by means of a draw key 60 received in a second bore 58 normal to but laterally displaced from axis of bore 21. The draw key is held in the position of Figure 3 by a lock nut 69 but is movable to a position (see Figure 4) to permit withdrawal or insertion of slide pin 19. The pin 19 is undercut at 17 and the key 60 is recessed at 64 but only one of these elements need be recessed. The pin 19 is one of two such pins slidably received in respective pairs of axially spaced bosses 14, 15 of caliper 12. <IMAGE></p> |
