It appears the rotor was rubbing against a clip for one of the pads; the only way for this to happen is if the rotor is not properly seated. If the rotors were held down with screws I could be sure. Also, one of the C clip for the lug was not on the lug, it was stuck against the hub. Anyway, I took it out for a while and no noise, I’ll keep checking since it didn’t do it every time, but more times than not.
