Recently ive noticed this strange squeak. After the car has sat for a bit (few hrs or so) when i back out of my parking space i hear this sometimes loud squak. It does not do this if i dont back out of a spot. The squeak only lasts for a few seconds. New brake rotors/shoes, calilers/pads all around. Does it in/out of gear with clutch in or out. No noticeable issues with the clutch or any other parts. Just an intermittent squeak..ideas?
