AMG brake systems aredesig nedfor
heavy loads.This may leadto noise when
braking. Thiswilldepend on:
R Speed
R Braking force
R Ambient conditions, e.g.temperature and
humid ity
The wearof individ ualcomponents ofthe
brake system, suchasthe brake pads/linings
or brake discs, depends onthe individ ualdriv-
ing style andopera tingconditions.
For this reason, itis impossi bletostate amile-
