Complete with pretty picture.
Which looks like a mechanically operated valve that would normally be on rear suspension somewhere.
Specifically says fitted to the CO6 models but you would need to work out what one of them is.

All I can suggest is looking round the suspension areas and seeing if you can find it.
If not, I reckon there isn't any proportioning valve as standard and any load sharing is down to brake design.
This is helpful, since this is for Bendix system, and i have Lucas system.
Will work on it next weekend. thanks for the tips. will take some pictures.

However i came to ask experts how the system works when there is no proportioning valve. Who does proportioning, master cylinder? and on which priniciple? Dont want to hunt the problem by changing parts that are alright.
