The "Bonding and Riveting" repair method involves replacing the watertight brazed connection with adhesive.
This gives rise to a new procedure for opening brazed connections.
Grind brazed seam with a belt grinder. This keeps the influence of heat in the area around the brazed seam as small as possible.
IMPORTANT:
Never use a gas flame.
All traces of brazing solder do not have to be removed.
Do not grind body panels thin.
