Drive Train - BMW M5 Owner's Manual

M carbon ceramic brake
The vehicle is fitted with a high-performance
braking system with perforated carbon ceramic
brake discs designed for use on racetracks.
Due to properties of the materials used, braking
may be associated with louder function noises,
particularly in wet conditions, just before the ve‐
hicle comes to a stop. However, this has no ef‐
fect on the performance, operational reliability
and durability of the brake.
The effects of moisture and road salt, from using
a carwash or dew formation overnight for exam‐
ple, may render the braking effect comparable
to that of a conventional braking system. This
may be perceived as reduced braking effect and
can be compensated for if necessary by press‐
ing the brake pedal harder.
Before washing the vehicle in an automatic car‐
wash or wash tunnel, clean the brake discs and
brake calipers with a steam jet or high-pressure
washer as well, to prevent encrustations and dirt
build-ups, caused by salt crystals, for example,
if the car is immobile afterwards. The cleaning
effect of automatic carwashes or wash tunnels
is usually not adequate for this in the area around
the wheels.
To do this, also follow the instructions in Wash‐
ing the vehicle, refer to page 198.

Drive train

With this vehicle, particular value was placed on
the direct connection from engine to the drive
train. Due to the torsionally rigid design of the

drive train, as is typical in a sports car, the trans‐
mission of the torque also gives acoustic feed‐
back.
When there are load changes, this may result in
clacker noises. They do not cause any impair‐
ment of the operation or the service life of the
components.
