I just noticed this issue a week ago. It seems like when I slow down (10MPH or less) or come to a stop I hear a squeaking sound coming from the passenger side. It doesn't do it every time, but I have been hearing it. I am thinking that it isn't the brakes, because I can hear the squeal when I slow down with my manual transmission, without braking. I got like 80 something thousand miles on my car.
