2.12.4. CHECKING AND TOPPING UP THE
REAR BRAKE FLUID
Carefully read 1.2.1 and see 1.3.1 .
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
2.12.5 .
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.
•
Keep the vehicle in vertical position, so that the fluid
contained in the tank (1) is parallel to the plug (2).
•
Make sure that the fluid level exceeds the "MIN" mark.
•
If the fluid does not reach at least the "MIN" mark, top
up as follows.

TOPPING UP
WARNING
The brake fluid may flow out of the tank. Do
not operate the rear brake lever if the brake
fluid tank plug is loose or has been removed.
•
Undo and remove plug (2).
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 reservoir open ONLY for
the time necessary for topping up.
