15.3 Electromechanical disc brake,
drive motor
The brake is a single stage electromechanical spring force brake that
releases when the magnetic coil is energised.
The brake acts as a parking brake, emergency and a third travel brake
at the end of the brake pedal's stroke.
The resistance in the coil is approx. 32 ohm at 20 degree Celcius.

15.3.1 Assembling

• Fit the brake on the motor shaft.
• Fit the O-ring (10) in the groove on the hub
• Ensure that the friction disc (4) is centred in relation to the magnet
housing before you try to install the brakes.
It may be necessary to energise the magnet coil with 48 V DC to po-
sition the brake disc.
• Fit the brake assembly onto the motor. Check that the splines on the
friction disc were not damaged during installation.
• Fit and tighten the brake unit's three securing bolts.
• Check the play between the magnet housing and the pressure plate
with the brake applied, should be 0.25-0.40 mm.
The play may need to be adjusted, see section adjustment.
• Connect the brake cable (11) to the truck's electrical system.
• Switch on the ignition switch and release the parking brake.
Check that the friction disc rotates freely.
Cut the voltage and check that the pressure plate locks the friction
disc and that the play (0.25-0.40 mm) is correct.
NOTE!
The seat switch must be made.
Use the strap contact 159747 to strap the switch so that you can work
without the need of sitting on the seat.
Bear in mind safety, the system is energised.
