41 00... Opening Brazed Joints
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 BMW 128i, 2012 BMW 128i, 2011 BMW 128i, 2010 BMW 135i, and 2010 BMW 128i. 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.
