Depending on how much the bike sat, and how much it was abused, rebuilding may not even be necessary, just a real good cleaning.
If you are handy, you will need to unbolt the calipers, but do NOT disconnect the brake lines yet. While the calipers are hanging there, stick a small screwdriver blade in between the brake pads and pump up the brake lever. Make sure the resevoir doesn't go dry too.... When the pistons are squeezing the brake pads, remove the screwdriver and brake pads. Stick something smaller and smaller in there and keep pumping. Basically, you are trying to force the pistons out of the calipers with brake fluid. Make sure you try and get all 4 pistons out at nearly the same time. Once one piston comes out, you have no more pressure anywhere. Unless you pinch off the brake line with a vise-grip or something like that. When the piston pops out, you'll have plenty of fluid, so have the rags ready!
yeah, you can use compressed air to get the pistons out, but if they are badly crudded up, you'll never have enough pressure to free the pistons with air.
Once the pistons are out, you remove the seals (two per piston) and replace them. Make sure you clean out the caliper and especially the grooves where the seals go. There are many places to get caliper rebuild kits, I like to use http://www.partsnmoreonline.com (For some reason, the board is filtering out the web address). There are others too.
The difference in the '82 Aspencade and Interstate isn't much. Already mentioned here, plus the two tone paint, colored seat, etc.. In '83 they gave it a nice digital dash.
