What I've heard is that the static brush is more of a vestige (on 5.25"
drives and smaller) than a necessary component.  At one time, on the
hard disks that had the diameter of hula hoops, it was crucial to damp
the static that would accumulate with use, else all kinds of spectacular
but annoying events would occur.  An engineer told me that the amount
of static which is generated by a well-built small hard disk is
negligible to none, and that the brush is probably more trouble than
it's worth (like the human appendix).
