BLEEDING THE BRAKING SYSTEMS

Carefully read 1.2.1.
For maintenance operations schedule, see
The air, if any, present inside the hydraulic circuit will serve
as "pad" by absorbing most of the pressure coming from the
brake master cylinder and thus reducing the callipers
efficiency during braking.
If some air is present inside the circuit, the brake control is
"spongy" and the braking efficiency is reduced.
DANGER
Safety critical operation. In order to avoid any
damage to both rider and vehicle, after brake
reassembly and after having restored the braking
system standard operation, make sure that all air
is bled out of the hydraulic circuit.
If the brake fluid gets in contact with the skin or
the eyes, it can cause serious irritations.
Carefully wash the parts of your body that get
in contact with the fluid. Consult a doctor or an
eye specialist if the fluid gets in contact with
your eyes.
WARNING
Handle the brake fluid with extreme care: it may
damage the vehicle paintwork and the plastic,
rubber and other parts.
In case maintenance operations are to be
performed on the hydraulic circuit, it is
advisable to use latex gloves.
When using the brake fluid, take care not to
spill it on the plastic or painted parts, since it
can damage them.
NOTE This vehicle is equipped with a braking system
consisting of:
- a front disc brake;
- a rear disc brake;
- a delay valve under the instrument panel.
Through the brake line (1), the action on the right (front)
brake lever exerts a pressure on front brake calliper pistons
A and C.
Through the delay valve, the action on the left (rear) brake
lever exerts a pressure on the front brake calliper piston B
and on the rear brake calliper.
NOTE To bleed air out of the circuit, proceed in the following
order: delay valve, front brake calliper and rear brake
calliper.
