A vehicle-washing apparatus which has a brush support mechanism which uses fixed support shafts and linear bearings, and a brush stabilization device using secondary fixed shafts. The entire weight of the brushes is supported by the fixed support shafts and the brushes are permitted to slide and pivot about the fixed support shafts via a primary bearing assembly having linear bearings which are sealed against air-borne contamination and which are provided with a self-contained lubrication system. A retraction/retention mechanism for the brushes uses a single continuous cable and a single air cylinder.
