hahahh obviously not where you are thinking.
Lube all contact surfaces between caliper, mount, and pads including:
Back side of brake pads
Don't forget any shims that are present between the pad and the piston.
If the pads have aluminum clips that "snap" them into the piston then make sure to lube these.
Style points count on this: don't slop it all over the place. I usually explain "too little" as: "If you're trying to be Picasso, you're not using enough".
Put a light layer of lube between the large center opening of the rotor and the hub, and on the rotor hold-down screw, if the vehicle has one.
This helps keep the metals from bonding/rusting together and requiring extensive force (some real swings of a hammer) for removal the next time it's needed.
If the caliper is equipped with slide pins, then pull them out of the caliper housing, clean them off, apply your lube, and put them back in.
Once you have the pins reinstalled, work them back and forth a few times to make sure that the lube is spread properly and there is no binding.
If there are metal slides that sit between the caliper and mount, lube (lightly) between the slide and the mount, and also between the caliper mount and where it contacts the brake pad ears.
