Absolutely. This is the first thing to do when a caliper starts hanging, not the last. The caliper pistons and their bores in the caliper body corrode. Brake fluid is hydroscopic, meaning it attracts water, which is what leads to this corrosion.
And no, those are not "slider" pins that go through the tabs on the tops of the pad backing plates and into the caliper body. They only serve to keep the pads from falling out, the pads do not "slide" on them. There is a great deal of clearance between the slots in the pad backing plates and these pins, the pads rattle around pretty freely on those pins. There should never be any "lubrication" of any kind on those pins.
Rebuilding calipers is pretty darn easy and the rebuild kits are pretty darn cheap. The only real problem can be getting those pistons out of their bores. Most of us use compressed air through the bleeder port, some pump them up with a grease gun.
