[Mgs] B/GT gearbox mystery

[Paul Hunt]

Exactly.  The only pressure of the release bearing on the cover plate 
should be from the light spring that is inside the slave cylinder.  When 
released you should be able to push the piston further back into the 
cylinder with the release arm, which displaces fluid into the master 
(watch it doesn't overflow).  When you release it again it should slowly 
come back out to put the release bearing back in contact with the cover 
plate.

That's what makes it self-adjusting - the piston moves out bit by as the 
release bearing and friction plate wear down, then is put back in again 
when you replace them.

It's exactly the same as calipers and pads.  Has anyone ever suggested 
you change the length of the pistons if you have a brake fault?  If they 
are too long you wouldn't be able to get the caliper with new pads over 
a new disk.  If they are too short you can push the seals past the end 
of the cylinders.
