There's no reservoir for pressure, like with vacuum brakes. Be sure your seat bolts are good before trying this!
P.S. I thought with the extra work the power steering fluid does, I changed the fluid in the reservoir several times over a few weeks. A litre is cheap enough.
And of course the serpentine belt was replaced.
Actually, there IS a reservoir. There is a small hydraulic accumulator that will provide oil pressure for one, possibly two assisted stops in the event of a pump loss. It is plainly visible. You can test yours by turning off the engine in your driveway/garage, and applying the brakes several times. You should notice increasing pedal resistance as the oil supply in the accumulator is depleted.
