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.

Note:

Push back the pressure plate (5) manually, while 

releasing the adjuster. This is to ensure that the 

pin of the adjusting screw remains in the slot of 

the pressure plate. Otherwise, there is a chance 

that the adjusting screw will start turning and 

damage the gaiter.

10. Remove the brake pads (3) and the pressure 

plate.

11. Check the pressure plate, the pressure plate 

guide and the brake pad slots for corrosion. 

Remove any corrosion carefully with a steel 

brush.

12. Shift the brake calliper towards the cylinder.

13. Check the dust covers, guide pins and 

adjusting screw for wear and damage. 

Replace in the event of damage and/or wear.

14. Shift the brake calliper manually over the 

guide pins and check the freedom of 

movement in this way.

15. Check the brake adjuster.

-

Hold the adjusting screw while turning 

the hexagon (7) anti-clockwise. Check 

that the piston can move freely.

-

Turn the hexagon (7) completely back 

(clockwise).

-

Depress the brake pedal lightly a few 

times to check that the automatic brake 

adjuster works.

-

Turn the hexagon (7) back (clockwise).

Installing the brake pads
If the brake pads have wear end indicators, they 

must be replaced at the same time as the brake 

pads, including accessories.

Note:

Brake pads must always be replaced on both 

sides of the axle.

1.

If necessary, turn the hexagon (7) back 

completely.

2.

Clean the brake pad seats.

3.

Place the pressure plate in the brake calliper 

and attach it to the adjusting screw.

4.

First, place a brake pad on the brake piston 

side.

5.

Shift the brake calliper towards the wheel 

until it touches the brake disc.
