Abstract
A master cylinder having a first housing with an axial bore therein which is connected to a second housing of a reservoir. The axial bore has a first replenishing port surrounded by a first boss and a second replenishing port surrounded by a second boss. A first radial bore in the first boss extends from the first replenishing port while a second radial bore in the second boss extends from the second replenishing port. First and second spigots which extends from the second housing are respectively located in the first and second radial bores to provide first and second flow communication paths from the reservoir to the axial bore. The first housing is secured to the second housing by a connecting arrangement characterized by a first pin that extends through the first boss and first spigot and a second pin that extends through the second boss and the second spigot to respectively retain first and second seals within the first and second radial bores without the introduction of side load forces which may provide a leak path between either the first or second flow communication paths and the surrounding environment.
