The output of a power steering pump is the high pressure side which goes to the steering box. It creates hydraulic pressure which makes steering much easier.

A power steering pumps as much as the power steering pump can pump.
Around 500 to 800
Rule of thumb says that it will make in excess of 1500 psi
Check the tension on the belt. A power steering pump will whine if there is too much belt tension, putting pressure on the side of the pulley.
Honda Accords are equipped with a hydraulic assisted steering system. The rotation of the motors crankshaft also drives the vehicles accessory belt system. The belts drive the power steering pump which pressurized fluid into the steering gear. The turning of the steering wheel actuates the rack-and-pinion to move right of left. The hydraulic pressure assists the gear in this movement. Without this pressure assist turning the steering takes much more force.
when the pressure gets high in the power steering system, its harder to turn the pump. when the pump is hard to turn it slows the engine rpms, acting a little like a brake on the engine. this sensor tells the computer how much pressure there is in the system and increases the idle to compensate for it.
Steering becomes much harder.
Brake fluid in the oil won't be much of a problem. It probably won't hurt anything, but to be on the safe side, just change the oil. In the power steering pump it will be harder to get out. You'll have to disconnect the high pressure line and let it pump out, then re-fill it with power steering fluid.
The 2010 Chevy Cobalt Power Steering costs about $400.
