Citroen XM Forum

hi all.(sorry for english, iam lithuanian) my xm is sinking in my eyes when the engine is off. so i think that brake control valve is fault. have anyone have new brake control valve or knows where i can get it? i need new. the price please.
happy new year.

Are you loosing any fluid from the valve as it is not an uncommon fault at least with S1 cars? Regards, Matthew T.

Are all the spheres in good order and before suspecting the doseur valve I would look at the FDV.
