A vehicle washing apparatus is provided with an improved side and rear washing brush system. A generally cylindrical side and rear washing brush is provided which is mounted for rotation about a vertical axis at the end of an arm terminating in upper and lower lateral members that carry the brush. The arm is rotatably mounted for lateral rotational movement with respect to a washing station framework and is biased so that the brush contacts the side of the vehicle as the vehicle moves through the washing station. As the vehicle passes the brush, a biasing means rotates the arm and forces the brush in behind the vehicle to maintain contact therewith and to traverse the rear of the vehicle with a force greater than that applied to hold the brush in contact with the side of the vehicle.
