14.4 Maintenance
The brake is included as a checkpoint in the truck's maintenance chart,
for intervals see the maintenance chart C-code P2.
Maintenance comprises inspection and adjustment of the play between
the pressure plate and magnet housing, wear, braking force and cleaning.
NOTE!
The friction surfaces must not come into to contact with oil or grease
as this will seriously reduce the brake's braking force.

14.4.1 Adjusting the play

• The play must be checked every 1000 operating hours.
• The play (A) is measured between the magnet housing and the
pressure plate in three positions, by the adjuster sleeves (6) with the
brakes actuated.
• Nominal play with correct adjustment is 0.25-0.40 mm.
• Maximum permitted play is 0.50 mm before adjustment is necessary.
Tools
• Feeler gauges, 14 mm box spanner and 6 mm allen key
• Loosen the three bolts (8).
• Adjust the play using the three adjuster sleeves (6) to 0.25-0.40 mm.
Measure, using the feeler gauges, by the side of the adjuster sleeve
when adjusting.
Turning anticlockwise reduces and clockwise increases the play.
• Tighten the bolts to 20 Nm.
• Recheck the play after tightening the bolts.
Repeat the adjustment if necessary until the play is correct.
• Check the play all the way around the pressure plate. Maximum per-
mitted deviation from the set play is 0.075 mm.

14.4.2 Wear

• Check the friction disc for wear every 3000 operating hours.
• Strip the brake as set out in the section "Dismantling".
• Measure the thickness of the friction disc. Minimum thickness = 8.0 mm.
