Cleaning, maintenance and repairs
12.5.8.3 Brake check on the hydraulic part of the braking system (specialist workshop)
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.
12.5.8.4 Checking the brake lining thickness (specialist workshop)
The brake lining wear must be checked every 500 operating hours, at
the latest before the start of the season.
This servicing interval is a recommendation. Depending on the de-
ployment, e.g. constant driving on hilly terrain, this may have to be
shortened.
Renew the brake shoes at a residual lining thickness of less than 1.5
mm (use only genuine brake shoes with type-tested brake linings).
When doing so the shoe return springs may have to be renewed.
12.5.8.5 Venting the hydraulic braking system (workshop)
After each brake repair, for which the system has been opened, vent
the brake system, because air may have entered the pressure lines.
At specialist workshops the brake is vented with a brake filling and
venting device:
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.
