▶
After every task on the plant and its equipment, perform a complete air bleed operation. The
fluid expelled from the hydraulic circuit during the bleed operation must not be re-used. For
topping up, only use the type of fluid prescribed, contained in sealed original recipients which
must only be opened at the time of use. Then verify the correct efficiency of the brake system.
Air bleed using “MODUS” or “E.A.SY.” on vehicles with ABS/ABD/EBD system
On vehicles equipped with ABS/ABD/EBD system, the conventional manual bleed operation may not be sufficient.
In this case, proceed with the operation piloted by the program included in “MODUS” or “E.A.SY.”.
This program ensures a complete bleed (primary circuit and secondary circuit of modulator) at item Fill/Empty Plant.
Follow the instructions as they are displayed, making sure not to exceed the pump and solenoid activation time to avoid super-
heating the components.
If this happens, the system switches off and you must wait for the preset time before resuming the operation.
▶
When replacing the modulator (supplied by IVECO Parts already filled with brake fluid in every
part), it is enough to use the manual bleed procedure, taking care however not to empty it and
not to cycle the pump and solenoid before filling is completed.
The ABS, ABD, EBD modulating devices are located on the chassis in the engine bay and must not be moved.
▶
Any such work must pay special attention to ensure correct connect on pipelines for each and
every wheel. Perform the necessary checks and controls after every such task at an Authorised
Workshop having specific equipment.
Load sensing valve
For vehicles that are still requested without ABS/ESP, a braking corrector version is envisaged for a single circuit linked with the
twin rear wheels (35C models).
Adjusting the corrector
Adjustment is performed at origin in the production factory and enables the vehicle to transport loads or to receive routine super-
structures, in compliance with the deceleration and road-holding values required by the related EC Directives.
Adjustment and control data are notified by a specific plate; its location on the vehicle is indicated in specific documentation.
If the corrector has to be adjusted differently, proceed as indicated below (see Figure 32).
