of the key features here is that the light spring inside the
slave cylinder will keep the train of working parts in intimate
contact. There will be no clearance or backlash between the seal
cup, piston, pushrod, release arm, release bearing, and the
input thrust plate on the clutch cover. This mechanism is
therefore self-adjusting to compensate for clutch wear and
gradual change of position of the operating parts, The graphite
faced release bearing will run with gentle intimate contact with
the release thrust plate. Graphite against a smooth steel
surface is self-lubricating, so it will last a long time before
it wears out (perhaps 80,000 miles or more)."</span></p>
<p>It's not physically possible for the hydraulic system to take up
play in part of that train without taking up play in all of it.
You can test this for yourself by using the release arm to push
the push-rod all the way into the cylinder, then release it. It
should slowly move back, while it is moving there is free play in
the linkage, when it stops there should be none. If yours doesn't
do that then the slave piston is sticking or the spring is missing
or broken. Make sure you have enough space in the master
reservoir before doing that to prevent an overflow, but with a
combined reservoir that is less likely to happen than with the
small clutch-only reservoir on the MGB.</p>

<div class="gmail_default" style="">Yes, the hydraulic clutch
will compensate for wear in the *clutch* components. But wear
in the operating parts (like the slave's pushrod/clevis)
results in lost motion - the first bit of movement of the
slave cylinder will only take up the slack and not actually
move the clutch fork. </div>
