ABSTRACT:
A hydraulic control apparatus, having a master cylinder, a slave cylinder and a conduit connecting the master cylinder to the slave cylinder, is made of separate modular units interconnectable by leakproof connectors. The apparatus is prefilled with hydraulic fluid while the separate modular units are interconnected, and after filling the separate modular units are disconnected and shipped to a user, unconnected but filled with hydraulic fluid. Alternatively, the separate modular units may be individually filled with hydraulic fluid, and shipped to a user unconnected but each filled with hydraulic fluid. After installation on a utilization device, for example a motor vehicle, the complementary connector members are reconnected for placing the individual modular units in hydraulic fluid communication. The connectors take the form of complementary members which are arranged to open fluid passageway during connection. A one-way locking or retainer clip is disposed in one connector member for interlocking engagement with appropriate abutments in the other connector member for preventing separation of the members after coupling. The connector members may be disconnected by using an appropriate tool, or by providing a disconnect element built in one of the connector members, to enable disconnecting the members after installation of the apparatus on a motor vehicle for example, for the purpose of repair or replacement of components.
