Brake master cylinder

[xrunnr]

I am rebuilding the dual brake master cylinder for my 109 but I have run into a problem. Everything was coming apart just fine but once I got the the "B" plunger I couldnt get it to come out. I can push it back down into the cylinder and it will pop back up to it original spot but it will not come out. I even put the air compressor on it and it still will not pop out. It seems to be hitting something but there is nothing in front of it in the chamber. Has anyone come across this problemand would know how to get the plunger to pop out? Any help would be great!

Have you removed the hex fastening on the front feed from the reservoir?
This holds the piston in place.

If the front feed is the one closest to the vacuum, yes I took a hex screw out and that released the longest plunger "A". The other or “B” plunger is the one that won’t come out. Is there anything holding it in other that the front "A" plunger?

I dont see another hex fastening, am I missing something?
