[Alan]

Hi Jim,
No, England till 26th.
Went to the Cherbourg submarine museum in Normandy on the way.
Well worth the visit & have taken oodles of photos.

This gives you better brake force, but it would hurt you when you put water pressure against it.  You want a small piston like a hydraulic clutch in a car.  I would use the clutch parts because they would also be aluminum and much tougher.  You would need to remove the piston and machine an o-ring  glove because the normal seal is designed to push in one direction only.
