Problems with Civic 2004 Hydraulic Bomb

Good afternoon everyone I have a problem with my Honda Civic 2004 has 56 thousand miles right that starts to sound ugly the Hodraulic Eye pump and the banada is schoing, I rebel by leaks and air inputs everything is fine, so I decided to disassemble the pump to the bomb and not grat is intact as new to the arm again and the liquid gives it to it and I put it to the liquid. Boot for the oil boat plug that believe it can be the problem sympre sounds and the truth has my hair,
thank you,
I hope your answers

Usually that symptom is air in the Deves system and it already comes out because a against precion is generated.

Good afternoon, how I make that purge
you could be more explicit thanks

Sorry I thought that savias, well lift the vehicle the two front wheels, start and move from end to end the direction loading the steering wheel a bit when you reach the top, this is done without the cover of the installed container, and you are filled tail up, be careful because on the occasion it is possible to commit the twin to put the drive strap incorrectly and the pump turns to the other way.
