REAR BRAKE
CHECKING
Position the vehicle on firm and
flat ground.
◆ 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 the “ MIN ”
mark, provide for topping up.
TOPPING UP
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.
◆ Unscrew and remove the plug (2).
Avoid any prolonged exposure
of the brake fluid to the air.
The brake fluid is hygroscopic
and when in contact with the air it ab-
sorbs its humidity.
Leave the brake fluid tank open ONLY
for the time necessary for topping up.
In order not to spill the brake flu-
id while topping up, keep the flu-
id in the tank parallel to the tank rim (in
horizontal position).
◆ Remove the gasket (3).
◆ By means of a syringe, top up the brake
fluid tank (1), see page 81 (LUBRICANT
CHART) until reaching the correct level
between the “ MIN ” and “ MAX ” marks.
It is advisable to top up until
reaching the “MAX” level only
with new pads.
When the disc pads wear out, the level
of the fluid decreases progressively to
compensate for their wear.
Do not reach the “MAX” level with worn
out pads, since this will cause a fluid
outflow when the pads are changed.
◆ To reassemble the components, follow
the reverse order.
Check the braking efficiency. If
necessary, contact your Conces-
sionario Ufficiale aprilia .
In case of excessive stroke of the brake
lever, of excessive elasticity or in case
there is air in the circuit, contact your
Concessionario Ufficiale aprilia , since it
may be necessary to bleed the system.
