BRAKES
Bleeding the front braking system (SMS)
A long travel and mushy feel of the brake lever indicate that there is air in the
system and the brake needs bleeding. Bleeding is also required after changing
brake fluid.
To bleed the front brake, begin with the control on the handlebar and then
bleed the calliper: the procedure is the same.
Proceed as follows.
- Take the rubber cover off the bleed valve (1) or (1A).
- Attach a clear plastic hose to the calliper bleed valve and place the other
end of the hose in a vessel (make sure the hose end stays dipped in the
fluid throughout the procedure).
- Remove the reservoir cover (2) and the rubber gaiter and fill the reservoir
with fresh fluid.
- Slacken the bleed valve and operate the lever repeatedly until the fluid
flowing out of the hose looks clear and free of air bubbles: now tighten the
bleed valve.
- Top up fluid level (A) and refit rubber gaiter and reservoir cover (2).
Fluid level inside the reservoir shall never drop below the minimum
notch during the bleeding procedure.
Brake fluid is corrosive. In the event of contact with eyes, rinse
with abundant water.
Motorcycle handlebar must be turned to the left during the bleeding
procedure. This will keep the master cylinder reservoir higher, making
bleeding easier.
The bleeding procedure does not remove all air from the circuit;
any small amounts of air left in the circuit will disappear after a short
period of usage; this will eliminate the mushy feel of the lever and restore
its travel to proper length.
If brake lever or brake pedal feel mush after a fall or a repair resul-
ting in loss of braking, bleed the circuit as described above.
Bleed valve tightening torque: 12-16 Nm, 1.2-1.6 Kgm, 8.8-11.8 ft/
