Self-adjusting disk brakes

Kim said:

My rear brake pads rub a bit on the rotor. I read on the Hayes site
(and elsewhere) that to adjust the distance from the rotor to the pad
you should:

1) push a couple of business cards between each side of the rotor and
the pad
2) pump the brake lever a few times
3) remove the business cards
4) pump the brake lever a few times

I can't see that this does anything and I just don't understand the
principle behind this procedure. If the brake pads are self-adjusting,
won't step 4 undo anything that was done during the previous steps?
Does this procedure really work?

Thanks,

I use two pieces of a soda can on each side of the rotor. Loosen the
bolts holding it to the post/frame, then do the squeeze routine holding
it on the final squeeze, tighten the bolts. Viola, centered discs
(well, works for me).

Musical discs?

I like to first clean those soda can shims with isopropyl alcohol to keep
your finger oils off of the pads. Before I put the shims in, I dowse the
caliper assembly and rotor with the IA and spin the wheel while holding a
paper towel soaked in IA, on the rotor.
