vw camper t2. servo breather

[dobber]

Hey up all  , can anyone enlighten me on the pipe that is tucked up under the front drivers  wheel arch in steel [apx 15mm] goes through the inside and appears to join to a  flexi pipe and go to the servo for brakes, was slotted on but no way was it tight enough to achieve  anything.
does it need to be there or can it go anywhere , been repairs bodged round it so ripped it all off.
cant get photos up. on phone and wont upload.

hey up mike.  been a while.
the steel end,  ends with a open rubber gromet end and appears to end between the inner and outer wheel arch. the flexi end is on the servo but was a loose raggy end fit that was not tight enough to seal., servo is  right underneath  the bus in a  very exposed area. cant get photo as all cut off.

cheers Archi, will check the flexy bit  as it looks like that may be a non return valve in the middle.  is there an index where that diagram came from.
