How can I test my hydraulic booster?

Will I need to retain my master cylinder pushrod?

Will I need to bleed my power steering system after installation?

What type of fluid does a hydraulic booster require?

As part of the power steering system, hydraulic boosters require O.E. power steering fluid.
