Thank you Barten! Yesteray i saw on a picture in the repair manual that the springloaded thingy indeed is supposed to be there. I have not opened the old cilinder yet but I suppose it is in there as well.
I hope replace the master cilinder this afternoon. followed by the bleeding which I know is a pain . I once fitted a one way bleedscrew in the rearbrakes so that helps I hope.

So succes!!!!!

I used the old connectors from the old master cilinder. They fit like Barten pointed out.





I ended up using the backplate of the actionvalve because the new one had very little room between the cilinder and de hose. The old one was poining the right direction and has moor room for a hoseclamp.

I mounted the new master cilinder and we have brakes!! Bleeding went wel. Blocked the 5 way junction with a torx bit. Then first bleed direct at the brakeservo . Then the frontwheels and then the rear. Luckily there was no air in the rear!

Thanks all for your help!! The mastercilinder was the culprit!

As I've said, mine is irregular, and can be pumped to give resistance further out. Which indicates that the rears aren't ratcheted up as close as they should. Sometimes, the pedal action is softer, progressive and smooth exactly like a modern. But usually not. Glad you've sorted yours!

Glad to hear your brakes are sorted. Are you happy with them, if you compare to a newer car? My brakes could have been much better, but i am searching for the reason why they are not as good as I had hoped. It seems like they have no servo assistance.

I am happy compared to what it was. My 1980 Volvo 245 or 2006 Volvo V70 brakes much better. All is relative. I think this is as good as it gets for now.
But I agree it could be better indeed
