A master cylinder assembly has a stamped steel reservoir and a cover in which a switch, appropriate electrical conduits, and a connector are integrally molded. A fluid level sensor float and rod are arranged to open and close the switch depending upon the level of fluid in the reservoir. A diaphragm seal is assembled to the underside of the cover and has a rod guide provided for the sensor rod. The guide also provides a suitable vent between the fluid chamber of the reservoir and the otherwise sealed space between the diaphragm and the cover. The cover has a peripheral channel receiving a peripheral mounting edge of the diaphragm so that the diaphragm also acts as a seal between the cover and the reservoir housing. The sealing action is primarily radial, between a channel wall and the reservoir housing wall, therefore not requiring the cover to be tightly clamped in place in order to compress a seal. The cover assembly is snapped into place on the reservoir housing. The reservoir also has a plastic inserted baffle dividing the reservoir into a plurality of baffled chambers.
