So i noticed it today for the first time. I was getting my car wash and right before the entrance of the wash i had to make a slight right turn so I let the car role and stepped on the brakes to put it to complete stop. The car made a sound like my brakes where wet. So car wash done i tested it on the street brakes no sound what so ever. So im getting home steeper hill parking spot open at the bottom I let the car role and make the right into the spot same noise like wet brakes. Put car in reverse trying to duplicate the noise driving around. Nothing happened parked in the same spot no noise. Should I be worried or what can cause this?
