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!!!!! 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?
