MAINTENANCE
WARNING
Top up to "MAX" level only after changing the brake
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.
In case of excessive stroke of the brake lever or
reduced efficiency of the braking system, contact an
aprilia Authorized dealer, since it may be necessary
to bleed the system.
REAR BRAKE
Check
• Set the vehicle in vertical position.
•
Make sure that the fluid level exceeds the "MIN" mark.
MIN = minimum level
If fluid does not reach at least "MIN".
WARNING
When the disk pads wear out, the level of the fluid
decreases progressively to compensate for their
wear.
• Check the brake pad wear and the disk wear.
If the pads and/or the disk 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 screws (9) are
loose or, most important, if the brake fluid tank
cover (10) has been removed.
• Using a wrench, loosen the two screws (9) from the brake
fluid reservoir (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 tank (2) open ONLY for the
time necessary for topping up.
•
Raise and remove the cover (10) together with the screws
(9) and the gasket (11).
WARNING
In order to avoiding spilling brake fluid while topping
up, do not shake the vehicle.
Do not put additives or other substances into the
fluid.
If you use a funnel or other similar items, make sure
that they are perfectly clean.
