Steve,
Often corrosion is all that keeps the piston from sliding out once the
pushrod is removed.  I have found that the best way to get a stuck piston
out is to bang it gingerly on a block of wood until the piston comes all the
way to the front of the bore.  Then angle the master a bit and bang the
thing on the wood so that only the edge contacts the surface, allowing the
piston to come clear of the body.

The wood will not damage the aluminum body.

Hello, Triumph fans -
 
I am not a Triumph guy, but have a '66 Austin-Healey 3000 (since 1984) and a
'73 MG Midget (since 1987).  I've been on the Healeys list for 13 years and
just signed up here.
  
I'm helping a neighbor resuscitate a '79 Spitfire 1500 that he bought on
eBay.  At the moment, we are rebuilding the clutch system.  
My question is:  how do you disassemble the clutch master?   The Haynes
manual isn't much help.  It says (page 135, section 3):
"5.  Referring to Fig. 5.3 pull off the rubber boot to expose the circlip
which must be removed so the pushrod complete with metal retaining washer
can be pulled out of the master cylinder."  [DONE]
"6.  With a small electrical screwdriver lift the tag [tab?] on the spring
retainer..."  This step appears to apply to the valve assembly inside the
cylinder, but nothing tells you how to get the valve out.  The piston is
free to move and the cylinder bore is clean.  Air pressure will push the
piston out only until the reservoir port is uncovered, then pressure is lost
and the piston stops.  Is it supposed to be shaken out somehow?  I haven't
had any luck so far doing that, and before I bust something I thought I
would ask the experts.  Although I suspected it would happen I tried it
anyway - pressurizing the cylinder with the reservoir cap on it just blew
the cap off.
 
Thanks very much!
