If it goes away when you step on the brake, you should also check for missing brake pad anti-rattle springs. If the rotor is slightly warped, and the anti-rattle springs are missing, the pad will be lifted and then drop back once per revolution and make a rhythmic clunk at low speeds. Stepping lightly on the brake clamps it in place and stops the noise. I have this problem on both front wheels of my car, because Midas lost the springs when the previous owner took the car in for a brake job.
