How much ps fluid did you replace after repairing the hose?
Customer: replied 6 years ago.
I was using a 32 oz container, and put in around 3/4ths of it.
Expert:  Ray M. replied 6 years ago.

That should be enough fluid,it may be air locked,to bleed it you need to jack up the front end so the wheels are off the ground and turn the wheels back and forth stop to stop with the engine running,this should push the air out,then you will need to top up the fluid.

Why would it effect the brakes?
Expert:  Ray M. replied 6 years ago.
It will effect the brakes because the brakes use a hydroboost system that is run off the power steering pump pressure.
