Rebuilding clutch master cylinder

[John Mitchell <jmitch@snet.net>]

   I had a slow leak around the the push rod, so I bought a rebuild kit 
for the clutch master.  I removed the circlip and the push rod, but how 
do you get the rest of the guts out?  Bentley simply says to remove 
piston seals and spring without much elaboration.  Thanks for any help.
