    Long enough to get ALL its good removed. Just for the record the brakes on the hub this came off of were not sticking and still retracting sufficient enough to keep anything dragging. There is that spring between the shoes that also aids in the function. When it brakes the bottom shoe drops and drags and wears out rapidly seen that plenty over the years too.

    Gill.....when u show this to a coustomer and they ask is that bad how do u respond? What should I infer from the question? Lol

    Back to s cam tid bits

    If u leave them in there long enough with nylon bushings and no grease they will look like this. This is the riding surface fot the bushing next to the spline where the slack adjuster is. It will always wear more than the surface at the cam end and the cam end always wears more uniformly . It will also wear really bad on the backside that is what i was trying to display with the photo of this worn used s cam. Bottom in the photo.

    Back in the day it was common practice for some types to
    Flip them 180 and wear the other half down when they look like this It does take out a certain amount of slop and these r for sure beyond safe service I'd never reinstall this, accept for Captain Kangaroo, and I do have him for a coustomer.

    BUT

    It is defiantly a step that should be used when reinstalling just slightly worn ones, IE, all u guys. Get them all turned 180. In fact when reusing serviceable cams ALSO make a point of being sure they r all either as was or all flipped to keep them all in harmony. When just slightly worn u gotta look close to be sure too.
