Hello. I've in intermittent brake problem. The brake pedal feels like abs has kicked in and after a judder, it sinks lower to the floor. Brakes still work although van pulls to the right. However, I get a warning in the form of a whooshing sound from air vents. When I hear this I know the brakes are...

Not the oldest but makes me want to look after it and get it pristine all the more. My Bongo's birthday is 20.09.1995
