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.

2. BRAKING PERFORMANCE AND BRAKE EQUALISATION
2.1 GENERAL
EBS tyre class
The tyre sizes are classified into tyre classes.
This tyre class information is necessary
to be able to assess the brake presentation,
by measurements of brake force.
This tyre class information is also necessary
for the EBS system to be able to evaluate
whether the electric EBS unit is programmed
when the tyre size is changed..
Tyre size change in EBS system
If the tyre size is changed in an EBS system and
the tyre size of the front and rear axle no longer
fall in the same tyre class, the changed tyre sizes
must be programmed into the electronic EBS
unit.

Tyre size change in EBS 2 system
If the tyre size is changed in an EBS 2 system and
the tyre size of the front and rear axle no longer
fall in the same tyre class, it is not necessary to
program the electronic ESB 2 unit because the
electronic ESB 2 unit will automatically recognise
this change in tyre size.
OVERVIEW OF BRAKING FORCES OF
EBS SYSTEM
This overview lists the braking forces graphs
based on tyre size. These braking force graphs
apply to the prime mover with EBS; these braking
force graphs can be used to check the braking
performance of an EBS prime mover.
Graph explanation
1 Brake force per wheel (N)
2 Tyre size
3 Type of brake cylinder + brake lever length
(if applicable)
4 Brake drum design
5 Disc brake construction
6 Pressure in brake cylinder (P)
7 Reference line of measured braking force
per wheel; the example shows a brake drum
construction and a 27" brake cylinder with
a brake lever length of 165 mm.
8 Reference line of the measured braking force
per wheel; the example shows a disk brake
construction and a 24" brake cylinder.
