There's a thread about this he

some old G103 maintenance manual on the web http://tinyurl.com/G103MM
doesn't mention anything about changing brake fluid every two years as is
common in most cars, however the DG505 needs it done every 4 years.

This thread started with the necessity of replacing the brake master
cylinder, right? Did anyone mention why it needed replacement? My
first
guess is wear or corrosion in the cylinder bore causing it to leak
pressure. If this is the case, there are places that will bore the
cylinder and sleeve it with either stainless steel or brass. It's done
all the time for old cars.

On the other hand, I don't know anything about the legality of doing
that
for an aircraft brake system. And on the Gripping Hand, I would
probably
do it that way myself.
