Grob 103 Twin II Brake Master Cylinder
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.
