It's different to the MGB clutch slave then.  That has a spring which =
pushes the piston out to take up play and push the release bearing onto =
the clutch cover plate.  The cylinder is backfilled with fluid from the =
reservoir so you get the same travel as before.  You have to reduce the =
pedal throw to get less movement of the release arm - BT, DT.

For the other post one of the techniques in the MGB world is to clamp =
the push-rod and hence piston fully into the bore of the cylinder for =
bleeding, to push as much air and fluid out as you can before starting.  =
The piston doesn't retract at all on its own, the above spring is trying =
to push the piston out.

Easy to check, push on the release arm so the push-rod goes into the =
cylinder, then let go.  If it slowly comes back out again there is a =
spring inside.

  If the clutch is engaging/disengaging very near top of pedal stroke, =
you can shorten the clutch master pushrod a bit to provide some =
pre-travel for the pedal, which may be more for to your preference.
