I think that you might find the its not the springs that are the problem its the
bore of the cylinders them selves.
I consulted Neville and Andy on this very problem and they advised as follows:-
First strip the unit down into its basic components and clear out all of the
polishing
debris out and off all of the components.
locate the PTFE disc that retains the seal and carefully with 400 wet and dry
pare
down the edge to take approx 1mm off the Dia
Then clean all of the components and soak them in dot 5 silicone brake fluid.
The cylinders should recover as required but only if the brake system is
installed,filled
and bleed.
If you have had normal car brake fluid anywhere near the components the seals
are
scrap and need replacing.

Has anybody experienced the springs in the cylinder of the finger brakes not
being powerful enough to return the plunger assembly to its usual resting
position after operation?
If so, what is the cure?
