A bleeding device (1, 100) for bleeding air from a hydraulic system, which includes a bleed screw (2, 102) and a bleeding needle (3, 103) for unseating the bleed screw (2, 102) to enable any air trapped within the system to be bled. The bleed screw (2, 102) is receivable within a threaded bleed port (41) in a component of the system, such as a brake caliper (4). The bleed screw (2, 102) includes a socket (28, 128), a conical sealing face (27) and a radial fluid passage (24) between the sealing face (27) and the socket (28, 128). The bleed needle (3, 103) includes a plug (34, 134) for releasable engaging receipt within the socket (28, 128) of the valve member and a fluid passageway (31) which is in fluid communication with the radial fluid passage (24) of the bleed screw (2) when the plug (34, 134) is received within the socket (28, 128). The bleed screw (2, 102) is movable, in use, between a sealed position in which the sealing face (27) seats against the sealing face (43) of a bleed port (41) and a bleeding position in which the sealing face (27) is unseated to open fluid communication between the bleed port (41) and the fluid passageways (24, 31).
