3.3 REMOVAL AND INSTALLATION OF PIPE ON PIPE CONNECTOR

When disconnecting pipes and/or
quick-release couplings, ensure that
the relevant connection has first
been made pressureless.

Removal of pipe on pipe connector
1.

Remove the plug from the socket.

2.

Cut the pipe at right angles just in front of the
pipe connector.

Note:
When removing the remainder of the pipe,
do not use any sharp objects. This is to avoid
damaging the pipe connector. Damage to
the pipe connector could result in leakage.
Remove the remainder of the pipe using heat
or the "cutting point" of a soldering iron.

Installation of pipe on pipe connector
1.

Check that there are no burrs in the pipe.

2.

Check the pipe connector for damage.
If the pipe connector is damaged, the pipe
connector and socket must be replaced.

3.

Check that the pipe connector is clean and
grease-free.

4.

Fit the plastic cap onto the plug to prevent it
from being damaged during installation.

5.

Using the special tool (DAF no. 0694829)
and a plastic hammer, attach the pipe to the
pipe connector.

3.5 REMOVAL AND INSTALLATION, SPRING BRAKE CYLINDER

Removal, spring brake cylinder on drum brake
1.

Place chocks in front of and behind the
wheels and ensure that there is sufficient
system pressure (> 7.5 bar).

2.

Place the parking brake valve in the "Driving"
position. Unscrew the release bolt in the
spring brake cylinder with a 24-mm spanner
as far as possible (anti-clockwise).

3.

Place the parking brake valve in the
"Parking" position and disconnect the two air
pipes from the spring brake cylinder.

4.

Remove the yoke pin from the yoke and the
brake lever.

5.

Remove the attachment nuts and take the
spring brake cylinder from the support.

Installation, spring brake cylinder on drum
brake
1.

Fit the spring brake cylinder onto the support
and tighten it to the specified torque. See
"Technical data".

2.

Pass the yoke pin through the yoke and the
brake lever. The bracket should be flat
(tolerance < 0.4 mm).

3.

Connect the air pipes:
connection point (11); service brake,
connection point (12); parking brake,

4.

Pressurise the air reservoirs and put the
parking brake valve in the "Driving" position.
Turn the release bolt all the way in and
tighten it to the specified torque. See
"Technical data".

5.

Check the connections for leakage.

Removal, spring brake cylinder on disc brakes

Note:
Prevent dirt from entering the disc brake
construction and cover the opening.

1.

Place chocks in front of and behind the
wheels and ensure that there is sufficient
system pressure (> 7.5 bar).

2.

Put the parking brake valve in the "Driving"
position (provide sufficient system pressure:
+ 6 bar). Unscrew the release bolt in the
spring brake cylinder with a 24-mm spanner
as far as possible (anti-clockwise).
