ABSTRACT:
A reservoir (20) for a master cylinder (16) has a body (22) with an end member (82) attached thereto by tangs (92, 92' . . . 92.sup.N) that engage a surface (69) on a flange (70). A shoulder (86) concentric to peripheral lip (84) on the end member (82) retains a seal (96). A projection (90) that extends from the end member (82) acts as a stop to assure that a pin (52) on a lever (54) that carries a magnet (60) remains attached to arms (44) extending from the body (22). While motion may move the fluid in compartments (34 and 36) toward flange 70, shoulder (86) acts a first barrier and seal (96) acts as a second barrier to prevent fluid from leaking through the mechanically formed joint. If fluid is lost from the compartments (34 and 36) a float (58) tracks the fluid level and moves magnet (60) toward sensor (64) to inform an operator of the change in fluid level.
