BRAKES
Bleeding the rear breaking system
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 (A) (21 mm wrench) rubber boot and top up with
(DOT 4) brake uid.
- Attach a clear plastic hose to the bleed valve (1) on the caliper and turn the
other end of the hose into a container.
- Depress the pedal (2) and keep it full down.
- Loosen the bleed union letting out uid (at rst, 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 uid come out of the tube.
- Close the bleed union to the prescribed torque and check the uid level (B)
inside the reservoir before reassemblle the cap (1). If the bleeding operation has
be done correctly, the pedal will have no mushy feel. If not, repeat the
operation.
During the bleed operation the uid level inside the reservoir must
never be lower than the minimum level.
Should the motorcycle, due to a fall during a competition or shop
repairs, show some elasticity of the brake lever stroke, with a subsequent
braking efciency decrease, you’ll to repeat the circuit bleeding as above
described.
Bleeding valve tightening torque: 12÷16 Nm/ 1,2÷1,6 Kgm/ 8.7÷11.6 ft-lb
