I'm having a similar issue, I'm leaning towards shitty pads with a very linear brake feeling, The person who owned the car before me had the brakes done.
I would say put some new pads on, wearever's from advance auto parts have a pretty good brake feeling for a OE replacement pad, and they're cheap so that would atleast help in the problem. And plus it never hurts to replace your brake pads.
