Hello, I'm new to the group.
I have spent some time looking around the various forums and topics looking for some assistance with a Stag brake servo, I haven't found what I was looking for so here's the question (apologies if it has been asked / answered before, I did spend quite a bit of time looking before posting the question).
How does the shaft from the pedal come out of the disc which holds the diaphragm, see photo?
The disk appears to be rigid plastic, possibly bakelite. I don't want to risk damaging the disk by applying to much pressure in the wrong direction.
