This is hissing noise. Dodge 2500 cummins manual trans 4x4. Noise is at master cylinder where it bolts to the assist from the power steering pump. When steering is wheel is moved the hissing stops or when the brake is applied. Is there a diaphragm in that valve that is serviceable or is that valve just bad and has to be replaced?
