BLEEDING
3.4.1.
BLEEDING THE FRONT BRAKE SYSTEM
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 caliper
efficiency during braking.
If some air is present inside the circuit, the brake control is
"spongy" and the braking efficiency is reduced.
DANGER
It is fundamental that air is bled off the
hydraulic circuit after the brakes have been
refitted and the braking system has been
restored to its standard operating conditions,
since it would be very dangerous for the vehicle
and the rider not to do so.

While bleeding the hydraulic circuit, top up reservoir with
brake fluid as required. Make sure there is always some fluid
in the reservoir throughout the process.

Remove the bleed valve rubber cap.
•
Insert one end of a transparent plastic tubing inside the
front brake caliper bleed valve and the other end in a
container for collection.
•
Pull and quickly release the front brake lever a few
times, then keep it pulled.
