Start your car's engine and press on each brake pedal 20 times to push any excess air out of the system (it will take less effort than before because there is no more air in the lines).
Will air work itself out of brake lines?
It won't get better on its own, and it could get worse – eventually, a bunch of small air bubbles in the line will join together to become one big, dangerous bubble. So your brakes won't have their normal pressure – and they could fail entirely, McGraw says.

How do I know if my power steering pump or Hydroboost is bad?
If the pump never whines, or the engine never reacts to the load of the pump, suspect a bad pump or slipping belt. While not a perfect test, it is an indicator of a problem. If the power brakes work, but the power steering does not, disconnect the hydro-boost input and output lines and join them together.
How to collect draining fluid from a hose?
Place a large container under the fluid return hose in order to collect the draining fluid.
How does hydraulic brake boost work?
The hydraulic brake boost system uses fluid from the power steering pump (8) through the hydraulic boost inlet hose (3) and to the brake booster assembly (4) . In addition to supplying the brake system with fluid for increased apply, the power steering pump is also connected to the power steering gear (6) and cooler (7).
How does PS fluid work on a steering pump?
Anyways, PS fluid flows from the belt driven pump to the brake booster. From there, it returns to the steering gear, cooler, and ends up back at the pump. At 3-4 years old, the PS fluid is due for replacement. Steering pumps usually fail due to poor maintenance that only entails replacing the fluid since its lubricating properties is not infinite and the fluid eventually becomes saturated with contaminants made up of metals from the pump rotor and pieces of inorganic materials lining the hoses. You will flush the PS loop by removing the return hose at the pump, plugging the pump return fitting, and then begin filling the pump resv with new fluid just as the old fill approaches the emptying out of the resv. as it drains from the PS pump return pipe.
What happens if you don't flush your PS pump?
If you didn't completely flush the PS when you last replaced the pump, some might advise a more diligent approach at this point, before the replacement pump is damaged by the contaminates that remained in the system. These contaminants, in theory should inflict the same damage to the brake booster & seals as occurred with the original PS pump (underlying cause of spongy brake pedal maybe) so more importance should be placed on timely maintenance regarding a hydroboost steering system.

The orig steering pump could prob have run forever given a complete fluid replacement at the intervals spec by GM through their various literatures.
