For the maintenance intervals, see 2.1.1 (REGULAR
SERVICE INTERVALS CHART) under:
– Brake fluid.
a
CAUTION
If the brake lever features excessive free play, if it is
excessively spongy or in the event of air bubbles in
the circuit, bleed the system, see 2.17 (BLEEDING
THE BRAKING SYSTEMS).
The leak of brake fluid damages painted or plastic
surfaces.
Before setting out, make sure that the hoses are not
twisted or holed and that there are no leakage from
the connectors.
Do not use or mix different types of silicone or oil-
based liquids.
Do not use brake fluids taken from old containers, or
not sealed.
Prevent water or dust from accidentally getting into
the circuit.
CHECK
N
Remove the right side panel, see 7.1.4 (REMOVING
THE RIGHT AND LEFT SIDES).
N
Keep the vehicle in vertical position.
N
Make sure that the fluid level exceeds the "MIN" mark.
MIN= minimum level
MAX= maximum level
If the fluid does not reach at least the "MIN" mark:
a
CAUTION
When the disc pads wear out, the level of the fluid de-
creases progressively to compensate for their wear.
N
Check the brake pad wear, 2.21 (CHECKING THE
BRAKE PAD WEAR) and the disc wear.
If the pads and/or the disc do not need replacing, provide
for topping up.
TOPPING UP
Carefully read 1.2.4 (BRAKE FLUID).
a
CAUTION
The brake fluid may flow out of the tank. Do not pull
the rear brake lever if the brake fluid tank cover has
been removed.
a
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.
N
Unscrew and remove the plug (1).
N
Remove the gasket (2).
a
CAUTION
In order not to spill the brake fluid while topping up,
keep the fluid in the tank parallel to the tank rim (in
horizontal position).
Do not put additives or other subtances into the fluid.
If you use a funnel or other similar items, make sure
that they are perfectly clean.

N
Fill the tank (3) with brake fluid, see 1.6 (LUBRICANT
CHART), until reaching the correct level between the
"MIN" and "MAX" marks.
a
CAUTION
It is advisable to top up until reaching the "MAX" level
only with new pads.
Do not reach the "MAX" level with worn out pads,
since this will cause a fluid outflow when the pads are
changed.
Check the braking efficiency.
