'08 Acura TSX, squealing/squeaking when backing up?

did you have the struts checked out and also maybe there is some dirt or other substance stuck on the brake pads or calipers. How many miles do you have on your tsx. I own a 06 6MT tsx, bought new 11/06. It still has the original brakes after 120,000+miles. I do not race up to red lights and jam on my brakes.
