Dear All,

I am new to the forum. As I was looking on the net for a problem we have on our old Mercedes truck I stumbled upon this form and really hope that some members with technical experience can help me...

Altough it is about the brake system of the Mercedes 1013 1980 this was the closest forum I could post to.

The question is concerning the following:

We have air escaping in the middle vent seen on the picture. This is according to the local truck inspection not allowed. (if we park the truck with the engine of it looses pressure rather quickly on the brake system).
How can this be solved? or what is the problem on this?

Hope someone can help...
thanks to all...

Thank you for the speedy reply...
I was doubting of what kind of part it exactly was. I thought it was some kind of vent. But you suggest it is some kind of pressure valve?
Is it easy to get off, or should I get the entire unit off (or is this too complicated?)
