A hydraulic apparatus such as a bleeder screw comprises an inner end, an
outer end, and a main body extending between the inner end and the outer
end. The main body includes a first section having a threaded outer
peripheral surface a second section disposed between the first section
and the inner end. The second section has a smaller diameter than the
threaded outer peripheral surface of the first section, and an axial
length of the threaded outer peripheral surface is less than an axial
length of the second section. An internal fluid passage opens through an
outer peripheral surface of the second section at a location between the
inner end and the threaded outer peripheral surface, and the internal
fluid passage opens through the main body at a location between the
threaded outer peripheral surface and the outer end. Another hydraulic
apparatus comprises a first fluid reservoir having a first reservoir
chamber and a first reservoir outlet; a second reservoir having a second
reservoir chamber and a second reservoir outlet; and a common fluid
passage in fluid communication with the first reservoir outlet and the
second reservoir outlet to flow fluid from both the first reservoir
chamber and the second reservoir chamber to the atmosphere.
