Obviously it depends on what your dealer charges for the work, but in general, the maintenance plan covers more than just brakes and inspection. i.e. it covers, as indicated, oil service with microfilter change, Inspection I, Inspection II, annual oil change, brake service (pads, rotors, sensors), brake fluid flush, windshield wipers, topping off of fluids, and so forth. It's also a good selling point in case you will get rid of the car during the period.
