What I eventually learned back then is that SRAM disc brakes often have this problem (Shimano does not have that reputation, but hey sound is just vibration, so similar mechanical causes could apply)
The solution for the SRAM brake goose noise, which I don't see on this thread, is to take the brake pads out, apply a small dab of grease to the BACKS of the pads (obviously not the braking surfaces!), and for me that eliminated whatever vibration was causing the noise.
I think in my case, I got either lube or soap on the rotors and it got imbedded in the pads. The pads were ruined and in turn ruined the rotors.
My bike shop will do a lot of things for me for free. Torquing a caliper would be one of those things. My problem is time. Not home often, and one phrase my wife hates hearing, “I have to go back to the shop”.
