This is not a screeching sound, or other high pitch brake wear indicator sound. It really is a gurgling sound, and it doesn't happen all the time, just when cold or at low speeds, although I need to pay more attention today to see if it does it at low speed when warm.
My mom had her mechanic check the brakes before she gave me the car because she thought the sound meant brakes about to go out, she was told brakes were fine, and indeed it does brake well.
Any ideas?
