11.9.4.3 Brake check on hydraulic component of brake system (workshop work)
Brake check on the hydraulic part of the braking system:
check all flexible brake hoses for wear
check all brake lines for damage
check all screw unions for seal tightness
renew any worn or damaged parts.
11.9.4.4 Replacing brake fluid (workshop work)
If possible, change the brake fluid after the winter.
11.9.4.5 Checking brake pad thickness (workshop work)
Checking brake pad thickness:
The brake pads must be checked for wear every 500 operating hours
or at least once before the start of the season.
This servicing interval is a recommendation. Depending on the
deployment, e.g. constant driving on hilly terrain, this may have to be
shortened.
If the remaining brake pad is less than 1.5 mm, replace the brake
shoes (only use original brake shoes with type-tested brake pads).
When you do this, the shoe return springs may have to be renewed.
11.9.4.6 Bleeding the brake system (workshop work)
After each brake repair, for which the system has been opened, vent
the brake system, because air may have entered the pressure lines.
The brake system is bled in the specialist workshop using a brake
filling and bleeding device as follows:
1. Remove the equalising tank screw union.
2. Fill the equalising tank up to the top edge.
3. Fit the venting muff to the equalising tank.
4. Connect the filling hose.
5. Open the stop valve of the filling union piece.
6. Vent the main cylinder.
7. Via the system's venting screws, remove brake fluid until it flows
out clear and bubble-free. To do so, the transparent venting
hose, which leads to a collecting cylinder one-third filled with
brake fluid, is pushed onto the venting valve to be vented.
8. After venting the complete brake system close the stop valve on
the filling union piece.
9. Relieve the residual pressure coming from the filling device.
10. Close the last venting valve when the residual pressure coming
from the filling device has dropped and the brake fluid level in
the equalising tank has reached the "MAX" mark.
11. Remove the filling union piece.
12. Close the equalising tank.
