Removing air dryer filter element
1.

Bleed the air dryer by allowing it to
regenerate or by loosening the compressor
pipe (1), so that the interior of the air dryer is
depressurised.

2.

Remove the filter element by turning it
anti-clockwise using a filter strap spanner.

3.

The filter element should be disposed of as if
it were an oil filter.

4.

Clean the air dryer internally.

5.

Check the air dryer threaded connection (2)
for damage and then lubricate it sparingly
with grease.

Installing the air dryer filter element
1.

Lubricate the sealing ring of the new filter
element sparingly with grease.

2.

Fit the filter element by manually tightening it
until the sealing ring abuts. Then tighten the
filter element by hand (approx. 1 turn).

3.

Fasten the compressor line (1).

4.

Pressurise the system and then check the air
dryer for air leaks.

5.

Fill in the date on the sticker with a
waterproof felt pen by which the filter
element must be replaced (max. 1 year after
fitting).

3.18 REMOVAL AND INSTALLATION, BRAKE PADS

Make sure no fingers get trapped
between the brake calliper and the
brake calliper carrier during and
following removal of the brake pads.
Always take hold of the brake
calliper on the outside.

Removing the brake pads
1.

Apply the parking brake.
If the respective axle has spring brake
cylinders, place chocks in front of and behind
the wheels of another axle and release the
parking brake.

2.

Remove the wheels in question.

3.

Remove the hairpin spring (26) and washer
(45) from the yoke pin (44) of the locking
strip (11).

4.

Press the strip on and remove the yoke
pin (44).

5.

Check the strip for corrosion; replace
if necessary.

6.

Remove the sealing cap (37).

7.

Using a ring spanner and the adapter,
turn the hexagonal bolt (23) anti-clockwise
until the brake pads (12) can be removed
(a clicking noise can be heard).

Note:
Never turn the hexagonal adjusting bolt
without using an adapter. The adapter is
a torque safety and will break off when the
torque is too high. Without the use of an
adapter the mechanics in the brake calliper
may become damaged when the torque is
too high, so that replacement of the brake
calliper may be necessary.

8.

Remove the brake pads.

Note:
If the brake pads have wear end indicators,
they must be removed at the same time as the
brake pads, including accessories.

Installing the brake pads
1.

Check the brake calliper play.
See "Inspection and adjustment".

2.

If necessary, turn the hexagonal adjusting
bolt (23) back completely, using the adapter.

3.

Clean the brake pad seats.

4.

Check all brake calliper seals (guide bushes,
thrust pieces).

5.

Shift the brake calliper (1) towards the wheel
side.

6.

Fit the outer brake pad.

7.

Shift the brake calliper towards the brake
cylinder side.

8.

Fit the inner brake pad.

9.

Separate the inner brake pad from the thrust
pieces.

10. Position a feeler gauge with the correct

thickness between the brake pad and the
thrust piece of the adjuster with the
hexagonal adjusting bolt. See "Technical
data".

11. Turn the hexagonal adjusting bolt clockwise

with the ring spanner and the adapter until
the feeler gauge just fits. Remove the feeler
gauge.

12. Check the play between the end of the brake

pads and the brake calliper carrier
(see "Technical data"). If the play is too
small, material must be ground off the steel
plate of the brake pad. If the play is too large,
the brake pads and/or brake carrier must be
replaced.

13. Vet de afdichtdop licht in (zie hoofdgroep

"Technische gegevens") en plaats deze
terug op de remsteller.

14. Fit the locking strip (11).

15. Press the strip and fit the yoke pin.

16. Fit the washer (45) and the hairpin spring

(26) on the yoke pin (44).

17. Apply the service brake once and check that

the hub can move freely. If necessary,
increase the play.

18. Put the wheels back on.
