Carefully read 0.2.1 (PRECAUTIONS AND GENERAL
INFORMATIONS) and 1.2.4 (BRAKE FLUID).
Bleed the braking system after the first 1000 km (625 mi).
The air present in the hydraulic system acts as a bearing,
absorbing most of the pressure exerted by the brake
pump and reducing the effectiveness of the caliper action
during braking.
The presence of air is revealed by the "sponginess" of the
brake lever and by the reduced braking capacity.
a
CAUTION
Handle brake fluid with care; it may chemically alter
painted surfaces and the parts in plastic, rubber, etc.
DO NOT DISPOSE OF BRAKE FLUID IN THE ENVI-
RONMENT.

WARNING
Considering the danger for both rider and vehicle, it
is absolutely essential to bleed the hydraulic circuit
once the brakes have been refitted and the braking
system restored to its normal conditions. Proceed as
follows:
NOTE
Only for the front braking system.
First bleed the system using the bleeder (1) located on the
pump, and then using the one (2) located on the caliper.
Top up the brake fluid tank, see 2.17 (CHECKING AND
TOPPING UP THE FRONT BRAKES FLUID) and 2.18
(CHECKING AND TOPPING UP THE REAR BRAKE
FLUID).
Remove the plastic protection cap.
Insert a transparent plastic tube on the bleeder (1) on
the pump and then on the bleeder (2) or (3) on the cal-
iper and put the other end of the tube in a container.
Rapidly pull and release the brake lever several times,
then keep it completely pulled.
Loosen the bleeder a quarter turn so that the brake fluid
flows into the container; this eliminates the tension on
the brake lever, allowing it to touch the handgrip.
Tighten the bleeder (1), pull the lever several times,
then keep it completely pulled and unscrew the bleed-
ing screw again.
Repeat this operation until the liquid flowing into the
container is completely free of air bubbles.
NOTE
During the bleeding of the braking system, fill
the tank with as much brake fluid as needed.
Make sure that the brake fluid is always present in the
tank during the operation.
Tighten the bleeder and remove the plastic tube.
Driving torque of bleeder (1): 15 Nm (1.5 kgm).
Top up the brake fluid tank to the right level, see 2.17
(CH EC K IN G AN D T O PP IN G U P TH E FR O NT
BRAKES FLUID) and 2.18 (CHECKING AND TOP-
PING UP THE REAR BRAKE FLUID).
Refit the rubber protection cap.
