Am I supposed to hear that tapping noise, or the creak that happens when the car stops or changes direction?
The tapping sounds like something out of alignment in the brake - possibly as simple as something that's not torqued to spec, a rotor's not quite perfectly flat, or the splash shield on the back is hitting something. Sorry to say I'd just take it apart and put it back together again very, very thoughtfully. Also could get it up in the air, take the wheel off, and spin the hub to see if you can locate the exact source of the noise.
