Abstract: A hydraulic fluid bleeding apparatus for removing air from a closed hydraulic brake system. The invention includes a container, a sealable lid for the container, and two conduits air tightly mounted through the lid. The first conduit includes a liquid level check valve positioned at the inner distal end within the container when the lid is secured thereto for closing off the vacuum source to the inside of the container when fluid level therein reaches a certain level. The outer distal end of the first conduit is connectable by flexible hose or the like to a vacuum source such as that within a running engine's intake manifold. The outer distal end of the second conduit is connectable to the brake system's bleed valve or petcock. The inner distal end of the second conduit is maintained at negative pressure by the vacuum condition within the container to effect brake fluid withdrawal from the bleed valve.
