Master brake cyl

[Patrick Baize <speedracre@netzero.net>]

Hi All
    I have disassembled my 74's Master Brake Cylinder.  I can not get
the
rear piston shaft out. Its feels as though there is something holding it
in place.

I push it back with a screw driver. Then let go. It springs forward a
bit and stops
as if there were a circlip there stopping it

Any Ideas?

THnx
