Hi LFrank,
You should be able to see the piece of metal with all the teeth on it, that the pawl engages. This piece is held in place by both the main pivot bolt, as well as its own smaller bolt just to the rear of the pivot bolt. It can't go anywhere, but I guess the teeth could wear out over time.
Did you just have work done on your rear brakes? The lever has to be raised quite a bit before the first tooth can engage, so you may have to loosen the chrome adjuster nut on the lever to put some more slack in the cable.
If you decide to remove the pivot bolt to investigate further, remember that it is REVERSE THREADED (turn CW to loosen).
