    Hi all
    i have a 2001 2.0. A few weeks ago i was coming up to junction pressed the break pedal then lifted off, then went to press the break down as i pulled up, pedal was rock hard with no response. That was a fun seconds!!!!! :scared2: i have now noticed that the pedal is softer and is not smooth when pressed, the is also a hissing noise from the pedal when pressed. Can anyone shed some light?

    hard to be exact, but could be a vacuum leak, a faulty master cylinder, faulty ABS pump etc, try getting it VAG-COM'd to see if the ECU has recorded any errors.

    If you press the brake pedal down and hold, with the engine off, then start the engine the pedal should "sink" slightly as the vacuum builds when the engine starts, if not then the brake servo may have a vac leak.

    Is it a diesel? They have a seperate vacuum pump to create it cos diesels don't have vacuum of their own in the inlet manifold like a petrol car does, could be that.
