FRONT BRAKING SYSTEM BLEEDING
The braking system must be bled when, due to air in the circuit, the lever stroke is long
and spongy.
To bleed the system:
- Disconnect the brake caliper and position it so that the pipe
is perpendicular to the ground.
- Remove the pump body cover (1).
- Remove the anti-emulsion disc and fill up the
- Attach a clear hose to bleed the valve and run into a clear glass container as shown
in figure.
Make sure that the end of the hose is submerged in brake fluid during the entire blee-
ding operation.
- Open the bleed valve on the caliper and pump the lever. Allow the pads to contact
the disc.
During this operation, you'll notice that air bubbles will come out of the brake pump
reservoir. This is normal. Watch the hose. When new, clear fluid, without bubbles,
come out, close the bleed valve.
- Carefully pry the pads apart, using a soft pry bar, forcing them back into the caliper
housing.
Repeat the entire sequence until no bubbles are seen at the hose or in reservoir.
WARNING!
During bleeding the motorcycle handlebar must be turned left. Thus, the pump tank
will be higher, making the braking system bleeding easier Tightening torque for
bleed valve is 1,2÷1,6 Kgm (12÷16 Nm; 8.8÷11.8 ft/lb).
REAR BRAKING SYSTEM BLEEDING
The braking system must be bled when, due to air in the circuit, the pedal stroke is long
and spongy.
To bleed the system:
- Remove the reservoir cover rubber boot and top up with (DOT 4) brake fluid.
- Attach a clear plastic hose to the bleed valve on the caliper and turn the other end of
the hose into a container.
- Depress the pedal and keep it full down.
- Loosen the bleed union letting out fluid (at first, only air will come out), then, closing the
union slightly.
- Release the pedal and wait for a few seconds before repeating the operation until only
fluid
come out of the tube.
- Close the bleed union to the prescribed torque and check the fluid level inside the reser-
voir before replacing the cap.
