A fluid level indicator for a brake fluid reservoir is disclosed which comprises a socket and circuit board which, once assembled, are installed within a chamber integrally molded with the fluid reservoir. The circuit board is assembled to the socket, which is in turn attached to an instrument panel warning device. In an alternative embodiment, the circuit board is formed integrally with connector pins, and injection molded about to form a socket assembly. The assembly is then attached to the instrument panel and installed within the chamber.

Hydraulic brake fluid reservoir level indicator system

A reservoir for a master cylinder including an upper reservoir section forming a portion of a float damping chamber and a lower reservoir section forming a portion of the float damping chamber. The upper reservoir section and the lower reservoir section are so dimensioned so that when they are fastened together, they define the float damping chamber at least one metering orifice formed along their mating surfaces. This metering orifice allows fluid to flow between the float damping chamber and the reservoir of the master cylinder in a controlled manner. Thus, a float device provided within the float damping chamber will not be susceptible to initiating false signals.

A combination of a master cylinder and a fluid reservoir includes a master cylinder, a reservoir, and a pair of elastomeric seals between the master cylinder and the reservoir. The master cylinder has a first bore which defines a first reservoir seat and a second bore which defines a second reservoir seat. The first bore and the second bore are spaced a predetermined distance from each other. The master cylinder also has a rigid snap-in attachment seat disposed between the first bore and the second bore. The reservoir has a first cylindrical seating projection and a second cylindrical seating projection spaced the predetermined distance from the first seating projection. A snap-in attachment member is disposed between the first and second seating projections for alignment with and engagement with the snap-in attachment seat. The seals are disposed between each of the first bore and the first seating projection and the second bore and the second seating projection. When the snap-in attachment member is engaged with the attachment seat, the seals are both compressed between the reservoir and the master cylinder preventing any fluid leakage therepast.
