value, as specified in the table below.
As soon as this diameter is exceeded, the brake
drum must be replaced.

vehicle)
The ovality (deformation) of the brake drum is
checked with the drum in position on the hub,
or on a brake dynamometer.
Brake drums with cracks exceeding a width of
0.7 mm or a length of 50 mm may not be reused.

1.2 TIGHTENING TORQUES
Note:
The tightening torques stated in this section are
different from the standard tightening torques
stated in the overview of the standard tightening
torques.
The other threaded connections not specified
must therefore be tightened to the torque stated
in the overview of standard tightening torques.
When attachment bolts and nuts are replaced,
it is important that - unless stated otherwise -
these bolts and nuts are of exactly the same
length and property class as those removed.
SAFETY VALVE
BRAKE CALLIPER - BRAKE CARRIER
(1) Always use new bolts, provided with locking compound.
New bolts are supplied with locking compound already
applied.
(2) In the case of versions with Knorr disc brakes,
the attachment of the brake caliper against the stub axle
changed starting from production week 2002-25.
Five bolts are now used instead of six bolts. There is still
a hole for the 6
th
bolt (5) on the brake carrier, but there is
no hole on the stub axle.
