2.12.1. CHECKING AND TOPPING UP THE
FRONT BRAKE FLUID LEVEL
Carefully read 1.2.1
Check the brake fluid after the first 1000 km (621 mi) and
then every 4000 km (2485 mi) or 12 months, change it every
year.
WARNING
In case of excessive stroke of the brake lever,
excessive elasticity, or air bubbles, bleed the
air out of the circuit, see
When using the brake fluid, take care not to
spill it on the plastic or painted parts, since it
can damage them.
Before starting, check that the brake lines are
neither twisted nor worn out and that the
connectors are not leaking.
Do not use or mix different types of silicone
or oil fluids.
Do not use neither old brake fluid nor fluid
taken from containers opened for a long time.
Prevent water or dust from accidentally
getting into the circuit.
CHECK
NOTE Place the vehicle on a firm and flat surface.
•
Position the vehicle on the stand and steer the
handlebar completely rightwards.
•
Make sure that the fluid level exceeds the "MIN" mark.
•
If the fluid does not reach at least the "MIN" mark,
proceed as follows:
WARNING
When the disc pads wear out, the level of the
fluid decreases progressively to compensate
for their wear.
•
Check the brake pad wear, see
2.12.3.
•
If the pads and/or the disc do not need replacing,
provide for topping up.
TOPPING UP
WARNING
The brake fluid may flow out of the tank. Do
not operate the front brake lever if the brake
fluid tank plug is loose or has been removed.
Use a cloth under the brake fluid tank.
•
Unscrew and remove the cover (1).
WARNING
Avoid any prolonged exposure of the brake
fluid to the air.
The brake fluid is hygroscopic and when in
contact with the air it absorbs its humidity.
Leave the brake fluid tank open ONLY for the
time necessary for topping up.
