Maybe it's just me, but I would NEVER change brake pads without either
putting on new rotors or getting the current ones "turned" (re-surfaced).

Take the rotors off and take them to an auto parts store.  Most of them can
turn rotors (in my area, they would need the rotors for about two hours, and
would charge you around $25 for the pair).  But first, have them measure the
rotors to make sure they are still "turn-able" (that they aren't so thin
that there isn't enough surface left to effectively re-surface).  Unless
your brakes got down to metal on metal, they should be good to be re-turned,
though usually only once - the next time you put on new pads you will HAVE
to put on new rotors.

The biggest trick I have seen with these Kias is that sometimes those rotors
don't want to come off so easily.  You might need a block and hammer to pry
them off. But you won't get optimal braking performance unless the rotor
surface is perfectly smooth for the new brake pads.

Thankfully, even high quality ceramic brake pads for the Sedona are not all
that expensive.  So don't try to get the absolute cheapest ones out there.
Most of my area parts stores have a choice of two, and even the more
expensive ones are only in the vicinity of $40 for the set.

After that, few if any surprises.

Hope this helps.
