Although I have not had to rebuild the calipers (knock on arborite cubicle
desktop), while rebuilding the brake system on the DKW I went to a local
rebuilding shop and got a small jar of what they called "rebuilding fluid"
at no charge (they eventually got me in my wallet for sleeving the master
cylinder, so I guess the freebie was a good ploy).  It's about twice the
thickness of brake fluid, and worked perfectly for the wheel cylinders (the
seals did not swell or stick to the bores).
