DANGER!
Risk of brake function being lost.
When work is done in the brake system, there is a risk of brake function
being partly or completely lost.
Method
Preconditions:
• Truck switched off and the battery disconnected
• Motor compartment open
1. Remove steering yoke and tiller arm from the truck as a unit (See
the repair manual). Note the position of the cable grommet so that
refitting is done correctly.
2. Unscrew the brake retaining screws and disconnect the cable.
3. Remove the brake unit from the truck. Note the position of the
brake so that refitting is done correctly.
4. Place the parking brake on a workbench with the magnet housing
facing downwards.
5. Clean the brake using compressed air. Clean from the inside
outwards.
6. Repeat the cleaning as necessary until a 0.2 mm feeler gauge can
be inserted. If there are particles that cannot be cleared away with
compressed air, these may be carefully scraped away.
Measure the air gap between the magnet housing of the brake unit
and the movable pressure disc. Measuring must be done around
the entire pressure disc, both on the inside and the outside.
Note:
It is extremely important that an air gap of min. 0.2 mm is maintained all
around the brake. If the prescribed measurement cannot be
maintained, the brake must be replaced
7. Turn over the parking brake, and press the dust shield into place.
8. Turn over the brake unit again, and place it with the magnet
housing facing downwards. Use a suitable blunt tool to press on
the dust shield so that it is level with the upper part of the magnetic
housing.
9. Check the position of the dust shield.
10. Refit the brake unit according to your notes, and reconnect the
connector.
11. The brake retaining screws are tightened with 5 Nm.
12. Refit the tiller arm and the steering yoke, and tighten the retaining
screws to 23 Nm.
Make sure that the cable grommet is fastened properly and
according to your notes, when fitting it to the brake unit.
Concluding procedures:
• Connect the battery and close the motor compartment cover.
• Start the truck and check that the brake works correctly.
