A few ideas...
This might not work for the pugs it wouldn't have worked for the passat I was working on at the weekend either, but I'll get to that.
For the hondas the brake line is banjo'd to the calliper.
So if replacing a piston it's put a drift through the hole and push the piston out.
For the passat I used large pliers on the piston, held the calliper and wiggled it out.
Elsewise if/when that doesn't work, I have a small length of brake line rubber hosed to an old tyre valve with the rubber scraped off it.
Thus can be applied to a foot pump even to push the piston out the calliper. I have a compressor, but I've done it with a 12V mini tyre inflater previously.
