3.37.2 Bleeding the brake system
Figure 3.91
Following maintenance or other work on the hydraulic system, the brake system must be bled be-
fore use.
1 Top up the container with oil to the Max marking.
2 Connect a brake bleeding tool (max. 1 bar) to the main ram
or
connect the compressed air line and the control line to the tractor and apply the brakes
or
connect the compressed air line and the control line to an external compressed air source (max.
6 bar).
3 Bleed the system using the nipple (B), which is located adjacent to the brake line connections
at each wheel. Be careful! First bleed the wheel that is furthest away from the main ram (i.e.
the wheel furthest away on the right-hand side) and continue to bleed left wheel/right wheels
until all the air has been forced out of the lines. Connect the transparent hose to the nipple and
allow surplus oil to run into a suitable container. Close the nipple when no more air bubbles
can be seen in the hose.
If the oil is not topped up when the level is below the Min marking, there is a risk that air
NOTE!
can penetrate the system.
3.37.3 Replacing brake components
The brake system's main ram, wheel cylinders, brake pads and brake drums are wearing parts.
The brake pads must not be replaced individually. All the brake pads must be replaced si-
NOTE!
multaneously. The same applies when replacing the wheel cylinders, which must also all be re-
placed at the same time.
