Rotary brush apparatus usable in the environment of a street sweeper includes a generally circular plate to which are secured brush segments. The brush segments are secured to the plate by pins on plates movable vertically upwardly in response to rotation of a bolt. The use of the pin and bolt elements allow for the quick change of the brush segments. The pins move vertically upwardly and downwardly and are locked in place to keep from rotating by guide elements used for alignment purposes. Apertures in the plate allow for the visual alignment of the brush segments.
