they're not necessary from a mechanical viewpoint - they have no
relevance whatsoever when the wheel is on. they are however useful in
the way that curly describes, but that is a minor detail since behind
the hub is not exposed in the same way the front is. if you have any
problems, remove the caliper housing, remove the disk, clean, replace,
etc. 20 minutes, max.
