Abstract
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.
