hydraulic brake booster (power brakes)
In most hydro brake booster systems the pump also runs the power steering system so if the power steering works the pump is okay. It sounds like you have a master cylinder problem.
yes
The type of brake system with vacum assist will have a large diameter hose from somewhere on the intake manifold to the brake booster. The type of brake system with hydro-boost will have hoses from the power steering pump to the brake booster.
You may have air pockets trap in the cooling system.
The master brake cylinder has nothing to do with the rack and pinion steering. In some vehicles the power steering box and the power brake booster share the same hydraulic power assist system.
Cycle the ignition on and off several times holding it in the on position for a few seconds each time. Doing this 4-5 times will allow the fuel pump to pressurize the fuel system.
The centrifugal pump is use to transfer a larger flow rate of liquid in a low pressure stage, while the booster pump is use to transmit less volume of liquid in a high pressure stage.
you can pressurize the system to find a leak
pressurize the system
If you are talking about a normal house, all you need to do to 'pressurize the system' is turn on the main valve, then open up each tap/faucet in turn until water is flowing freely.
why do we need a steering system
