Caliper pad break-in

[Skip Osmundsen <gosmund@mail.jax.bellsouth.net>]

Hello all,
I'm about to install new semi metallic pads on my TR6 (one small item
in a long to-do list); anyway, I seem to recall reading somewhere that
it's a good idea to use some fine grain emory cloth on the rotors
to impart some fine scratches on the surface in a radial direction so
that the pads will wear in properly and not become glazed.  Can anyone
comment on this?
Thanks.
