DIRECTION PROBLEMS

Hello everyone. I have a 306TD Peugeot and when I turn the steering wheel several times to park or make a maneuver usually gets hard. But it only does after turning the steering wheel from side to two or three times. It is as if the assisted direction lacked. I would like to know if anyone knows that it can be devoid. The liquid level is fine. Thank you very much in advance.

Well, you tell us that the direction's liquid is fine, so what you can do is verify the state of the pump and other components; and also that water has not been leaked.

You review or reynestos The level of the direction fluid, there are two things to check the tension of the belt, and the pressure of the pump can also be the pump regulation valve, if in the end everything is well possibly have an internal pressure loss inside the box, also check the front train possibly some rotary or terminal of direction damaged.-

Thanks for your help. The front train is fine and there is no liquid leak. Could you tell me where is the valve? How is the pump pressure verified? How much does it have to give? Thank you.
