If the ISO7638 cable is not connected, the ABS and additional functions will NOT be
operative. In this case, the brake system will operate as a conventional brake
system.

It may be possible that a lorry/trailer combination does not brake properly. Upon further investigation, it
is usually found that in case of a trailer with drum brakes, the brake lining has been glazed or burnt and
the brake drums have torn. In case of a trailer with disc brakes, it appears the brake pads have
completely worn after a limited number of kilometres and the brake discs show deep grooves.
For articulated vehicles, the lorry as well as the trailer conform with European directives or the
regulations of the United Nations. In practice however, it appears that with a combination of these two
optimum braking is not performed. Nevertheless, it is most important that each of the vehicles takes its
share of the braking force in a correct manner and under any loading conditions.
Synchronisation of the brake system (see § 3.5) on the lorry and the trailer prevents these problems.
Please also refer to the additional documentation supplied with the trailer.

Between the first 2,000 and 10,000 km and after each change of lorry brake
synchronisation is recommended.
This brake synchronisation, which should be carried out by the lorry manufacturer, is recommended in
order to obtain optimum brake force distribution and an optimum wear pattern between the lorry and the
trailer.
Damage and wear as a result of poor brake synchronisation will not be accepted under warranty under
any circumstances. We therefore recommend brake synchronisation is performed and the
synchronisation report is kept in a safe place. Always ensure that the report clearly states the details of
the lorry and the trailer, including the date on which the synchronisation was performed.
Please also refer to the additional documentation supplied with the trailer.

As the braking system is fitted with EBS, the brake plate has been replaced by a sticker. The
parameters of the EBS controlled brake system can be found on this sticker.
The EBS system may only be checked by a recognised Wabco service point
which has the appropriate software.
