Was hoping someone can advise. I have 06 pre-facelift model 2.2 I-CTDI. Recently i've been having problems with the brakes. The pedal seems to be harder than normal and brakes are are sluggish to slow and stop the car. It seems to be worse at different times but not predictable in any way. I thought it was possibly the vacuum pump. I tested the suction from the pipe and there definitely is some suction from it. Im not sure how much there should be. Would a faulty vacuum pump account for these 'symptoms' i.e. Intermittent/varying degrees of poor braking? Is the vacuum pump problematic in thia model? Could there be something else i'm not considering?
