Dan,

I rode mine for years and tens of thousands of miles after I first noticed the
rattling. I finally changed them around 88K miles. I don't recommend waiting
that long.  A couple of the pins came out in pieces, but the carriers and
disks weren't damaged. See the three articles at http://ibmwr.org/ktech.shtml
, especially Mick's suggestion to re-orient the disk. Changing rollers is easy
to do with the wheel off the bike and doesn't take very long, either. There
was a noticable improvement in brake feel, but no change in brake performance
that I could detect.
