Hi there,
if this is a pulsation in the brake pedal, get the rotors machined, as one or more will be warped, just make sure that they check the thickness first as there is a min safe thickness that should not be exceeded.

I pulled the tires off and the front(outside) of rotor is smooth and the inside is a bit grooved. It was fine until we parked it and drove it minimal. Think sitting woudl cause them to warp, the pads have at least 3/4 left on them for sure.

You will not see this warpage we are talking about thousandths of an inch, .040"- .060" run out is enough to give you this pulsation, i would get it check out.
