Don't forget to clean up your caliper slide pins and put some brake grease on them before you put them back in. Also, you could probably get away with not doing this but you want to clean up the contact points for the pads on the caliper mounting bracket with brake cleaner and sand paper. I used a dremel with a sanding head that did a great job of cleaning them up.
If you are changing your rotors its a good idea to sand down the hub and put a light coat of antiseize on there to make your next rotor change a snap. You probably want to clean up the corrosion on the back of your rim where it mates to the hub so your rim won't get fused to the rotor assembly like mine were. I couldn't even get my tires off when I first attempted this job.
I've also heard that its necessary to change the clips that go over the front of the calipers every 48 months. Anyone have any insight on that?
