I have a 2002 Subaru Outback that recently started making an odd noise. This noise is somewhat hard to describe, but sort of sounds like “urrh ah urrh ah” almost like a rubbing noise or a deep squeak (not high pitched). This noise only occurs when I’m braking, starts when I’m slowing down (going below 20mph) and becomes more pronounced as I reach a full stop. The noise starts out fast (urr ah urr ah urr ah) and slows down as the car slows down (and gets louder as I come to a complete stop…urrrrrrh ahhhhh urrrrh ahhhhh urrrrrrrh). It is more pronounced when I’m braking going down a hill (louder than when I’m stopping on a flat surface). It does NOT do it when I’m braking in reverse, or when I’m braking going up a hill. You also cannot hear the noise outside the car- only inside the cabin. Anyone have any clues as to what this might be? Thanks!!!
