A housing ( ) for a master cylinder ( ) having a bore ( ) in which a piston ( ) is slideable to pressurize fluid ahead of a main seal ( ) on the piston for the supply of pressurized fluid to an outlet ( ). Two inlet openings ( ) are provided into the bore, a first opening ( ) for recuperation of fluid from an associated reservoir to that part ( ) of the bore ahead of the main piston seal ( ) when the piston is in a retracted position and a second opening ( ) placing that portion ( ) of the bore between the main piston seal and a second piston seal ( ) behind the main seal in permanent communication with the reservoir. The housing also has an external inlet connection ( ) formed integrally with the housing. The inlet connection has a free end for direct connection with a conduit ( ) connected with the associated reservoir and having a passage ( ) for connection with the conduit which opens into the housing bore at the first ( ) and second ( ) openings. The configuration of the passage and the first and second openings is such that the passage ( ) and the first and second openings ( ) can be formed by a single moulding core ( ).
