Actually, all I meant was to remove the pistons from the calipers and replace all the seals and dust seals with a caliper repair kit; as the calipers get older, sometimes bits of rust can work thru seals and get into the bore, causing seized pistons - it's an easy job, just the same as on any car you'll find, but you have to get the pistons out by pumping them out with pedal, unless anyone else knows a different way.
