I am about ready to hook up the power steering on a vehicle that received a 454 transplant. The Power steering feeds a hydroboost brake system. The lines are empty though I have had fluid in the pump for some time. I'm guessing I need to get fluid in the system by firing it up and then shutting down and filling repeatedly then start slowly working the wheels back and forth to get the fluid through the system. Then after fluid is in the system I assume I should pull a low pressure hose and start flushing with the engine running and keeping the remote full of fluid. Is this the proper way to add fluid and flush the power steering on a hydroboost brake equipped system?
