Interesting too is the design that sees the single piston in a "blind" cylinder. Can't knock out through the other end, near impossible to pull out unless the cylider is in good working condition.

Rich,
These are the same wheel cylinders as a Ferret. They are alloy and hence why corrosion can take place, especially if the gasket between backplate and cylinder is not in place or damaged, then water can easily enter. as with all brake systems, if neglected and not checked they can suffer. Once you have the cylinders off the vehicles, clean up the bore that is visible then drop them in a pot of boiling water, for a few minutes, take out, holding it with a leather glove and thump the open end down on a block of wood. This usually frees them, might take several goes at heating and thumping. You could also rig an airline on the pipe connection, but stuff a rag in the open end to save injury.
