2.15 Modifications to the Braking System
2.15.1 General remarks
!
The braking system and components are very important for driving safety and vehicle use.
No changes may be made to the following parts: brake cylinders and callipers, adjustment units and
valves, parking brake, brake control and auxiliary systems.
Any modification to the braking system requires authorisation from IVECO.
It is recommended that when new units are fitted they should be the same makes as those fitted to the original vehicle.
When required by n ational regulation s, the vehicle must be submitted for testing to the respective authority.
2.15.2 Brake pipes
!
Pipes must not be welded for any reason whatsoever.
In the event that the vehicle wheelbase is modified, the brake pipes affected by the change must be replaced by new one-piece
pipes. If this is not possible, fittings of the same type as the ones originally used on the vehicle must be used. When replacing pipes
the minimum internal dimensions of th e new pipes must not be less than that of the existing pipes.
The new pipes must have the same characteristic s and be of the same material as those used originally on the vehicle. The installation
must be carried out so that the piping is protected and the correct function of the system ensured.
For the supply and fitting of material we recommend that you contact our Service Centres or specialised workshops.
Metal pipes
For the hydraulic system pipes, any additions and replacements must be as follows:
- pipes (materials, dimensions, fitt ings): : ISO 4038 standard
- bending radii (referred to the pipe centre line = 4.76 mm): : min. 25 mm
- tightening torque:
