Abstract
A dual fluid reservoir for a tandem master cylinder includes front and rear fluid chambers communicated to each other and comprises a lateral partition provided within the casing of the reservoir to block free fluid communication between the two chambers after the fluid level within the chambers drops below a lowest level defined by the lateral partition, and an annular partition provided on the lateral partition to form a float chamber therein, the annular partition being higher than the lateral partition in a predetermined length and including a pair of recessed portions corresponding to the lateral partition to permit fluid flow from the two fluid chambers into the float chamber. Thus, a magnetically operable switch device is mounted on the casing between the two chambers to actuate a warning device and a float is disposed within the float chamber for vertical movement and operatively connected to the switch.
