DG also uses brake fluid with a EPDM (ethylene propylene)
O-ring at least on the 800/808. I would check the manual
for each specific model to determine which is used.
Even if you were to change the caliper O-ring to EPDM
you would still need to verify what is used for a seal
in the master cylinder and lines.

Another example is the Stemme S10 series, which uses
DOT fluid. Stemme uses
a Cleveland 300 caliper with the seals changed from
Buna-N to EPDM rubber.

NEVER use automotive brake fluid for the brakes in
gliders!
Automotive brake fluid will destroy the seals.

Except, of course, in those rare but not non-existant
cases where the
brakes were designed around automotive pistons and
seals. A good
example is the early (pre-MATCO) Rosenhan drum units
used on some 1960s
American gliders.
