Abstract
A hand-held bleeder stroke tool for bleeding gas from a cylinder/piston assembly, such as a vehicle master brake cylinder assembly. The present invention utilizes a rod with a push member at one end of the rod. The push member is generally spherical and contacts the piston of the assembly to force or stroke the piston into the cylinder and forcing the gas from the cylinder. At an end generally opposed to the push member, the rod is secured to a handle to provide effective gripping. Furthermore, the present invention utilizes a stroke indicator assembly comprising a slider movably mounted to the rod as well as length markings on the rod as visual gauging features for determining equal length strokes of the piston.
