here's the link from another post that goes into detail about "bedding" the brake pads.

this sounds right to me.
also, when doing brakes, be sure to use that little tube of lube that comes with them to lube the moving parts of your caliper or shoe assembly. it is very important that both halves of the disc brake squeeze the rotors equally and do not hang in a "closed' position. that can cause many bad things including low gas mileage, premature wear and eventual rotor and pad replacement and in the worse case, can cause your brakes to overheat to the point the fluid boils and you have no or very decreased braking power! same deal on the rear drums although not as likely or dangerous (probably?).
i toasted a set of rear calipers on my nissan by not lubing them with each brake shoe change. some moisture got in under the rubber grommets and rusted the inner caliper into an immovable state.
