41 00... Opening Brazed Joints
WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2013 BMW 328xi, 2013 BMW 328i, 2012 BMW 328xi, 2012 BMW 328i, and 2011 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.
The "Bonding and Riveting" repair method involves replacing the watertight brazed joint with adhesive.
This gives rise to a new procedure for opening brazed joints.
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.
