Abstract
A master cylinder assembly includes a housing and a cover coupled to the housing, defining a reservoir adapted to contain fluid at a level. The cover includes an aperture. A sight glass is received within the aperture and adapted to indicate the fluid level. The sight glass has a top portion, bottom portion, and middle portion between the top and bottom portions. The top and bottom portions each have a perimeter sized to be received within the aperture and to seal the reservoir. The middle portion has a reduced perimeter. The sight glass is movable between a raised position where the bottom portion is received within the aperture, sealing the reservoir and a lowered position where the top portion is received within the aperture, sealing the reservoir. The middle portion allows fluid flow through the aperture when the sight glass is moved from the raised position to the lowered position.
