But, but, but-- the main reason there is a problem, is that there is another
circlip under the nylon part. This is what keeps keeps the piston from pushing
it out. Even a lot of pressure isn't going to work, unless you expect the
piston to shear the circlip. (that would make a mess! )
I've tried tapping into the nylon with long sharp screws- no go. Best still
seems to be to break it up, and remove the pieces.
