It's more than likely to be the caliper not sliding on the pins. Very easy to sort.

Agreed, either the pistons are stuck because of salt and crud stick to the pistons and seals, or the sliding pins are stuck as Lozzo said.
One caliper at a time take them off and clean the pistons up, grease the caliper sliding pins properly using a rubber safe grease that won't harm the rubber boots. If you can push the pistons back into the body by hand that should be fine, if not I'd push the pistons out, pull the seals out and clean up the caliper body and clean & inspect the seals. New ones are unlikely to be a bad bet, but you can sometimes get away with using the old ones if they're in good nick, I certainly have on a number of occasions. This does mean bleeding the brake system through though so if you're going to pop the pistons out make sure you are happy doing this.

Yes you use the brake system to push them out if they're stuck, or compressed air if they move OK anyway. (after removing pads etc.)
I use this method, yes you do get some brake fluid over you but don't whinge it won't kill you (much), then I detatch the caliper from hoses, remove the seals, scrape any corrosion out of the seal grooves, clean them up with dremel brush thing, clean the rest of the caliper like where the pads sit with a wire brush, then use brake cleaner to get the lot sparkly clean, especially the fluid passageways. Then, I pack the seal grooves with red rubber grease, put the seals in and press them into the grooves and wipe out excess grease, keeping the amount in the cylinder itself to a minimum, wipe this excess over the sides of the piston and slide it back in. Copperslip the back of the pads, pad springs and retaining pin, rubber grease on the rubbers and put it all back together.

Having spent more hours doing this than some (6 pot tokico calipers on the ZX6R) I can say that hot water, an old toothbrush and some Jif/Cif/Ownbrand cream cleaner, work wonders on the pistons and caliper bodies.
The best tool in the world ever for cleaning up the recesses in the calipers was made by Sid Squid, who took a long nail, filed the head so it looked like a slice of cake / cheese (2 flat edges, one curved) and took the sharp points off. Then tapped it into a short length of broom handle as a holding point. Works well that does... Jambo
