Adjusting the brake air gap
IMPORTANT
The mechanical braking torque is factory set.
NOTE
This brake system is boosted by the pressure
in the lifting circuit.
– Check the brake in the engaged position, in
other words with the power off and with no
load on the forks.
– Check the air gap on the brake using a set
of shims. The original air gap is 0.25 with
a tolerance ranging from – 0.1 to 0.05 mm.
The maximum air gap after partial disc wear
is 0.5 mm. Beyond this, there is a risk of
the brake not releasing fully and a risk of
overheating.
– If the air gap is close to the limit value of 0.5
mm, it must be adjusted.
To do this, it is necessary to:
– Tilt the tiller support backwards.
– Loosen the three mounting screws (3).
– Adjust the three banjo bolts (4) to set the air
gap to its original value of 0.25 mm.
– Retighten the three mounting screws (3).
– Check the air gap at three points at 120°
intervals.
– Make sure that the air gap is equal right
around the brake.
– Return the tiller support to its original
position.
– Switch on the ignition and check that the
brake releases completely.
NOTE
Use an offset open-ended spanner to adjust
the banjo bolt (4) at the bottom near the
chassis.
We recommend that this work is carried out by
our service engineers.
