This is a common fix for antique car and other auto restoration projects.


but is it a valid repair for an aircraft?
is the Grob flown under a Standard airworthiness certificate or an
Experimental?

it does make a difference..

I can see the accident report now, Grob on Commercial passenger carrying
scenic glider ride, lands long and goes off the end of runway.. brake fails
to stop the glider before hitting airport fence. Fencing injures passenger's
face in front seat. Discovered improper repair to brake master cylinder.
Lawsuit follows.....

you get the picture.
