Put in simple terms, the procedure for replacing pads ought to be what needs to be understood by an owner confronted by what the OP's asking about, right?
Remove wheel, push pistons outward as far as possible, remove old pads, insert new pads, reinstall wheel, then give a couple quick squeezes on the brake lever. DO NOT squeeze brake lever while wheel is removed, DO NOT open the bleed port.
The whole thing should take ten minutes, unless they are the fiddly Shimano brake pads that are sometimes tricky to reinsert (well, for me anyway) properly.
