REAR BRAKE

CHECKING
NOTE
Position the vehicle on firm and
flat ground.
WARNING
Danger of fall or overturning.
When the vehicle is straightened from
the parking position to the driving
position, the stand goes automatically
up.
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
CAUTION
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).
◆
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.
NOTE
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).
Remove the gasket (3).
◆
By means of a syringe, top up the brake
◆
fluid tank (1), see p. 76 (LUBRICANT
CHART) until reaching the correct level
between the ≈MIN∆ and ≈MAX∆ marks.
CAUTION
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.
WARNING

necessary, contact your aprilia Official

In case of excessive stroke of the brake
lever, of excessive elasticity or in case

aprilia Official Dealer, since it may be
necessary to bleed the system.
