- Remove fluid reservoir cap (2), the rubber and fill the reser-
voir with fresh brake fluid.
- Open the bleeding valve and pump with brake lever (3) sever-
al times until the fluid, clear and without bubbles, comes out of
the hose: now close the bleeding valve.-
- Restore the brake fluid level (A) then reassemble the rubber
and the fluid reservoir cap (2).
During the bleed operation the fluid level
inside the reservoir must never be lower
than the minimum level.
Tightening torque for bleed valve is 1,2 ÷
1,6 kgm (12 ÷ 16 Nm; 8.8 ÷ 11.8 ft-lb).
As the braking fluid is a very corro-
sive substance, in the case it comes
in contact with your eyes wash
them abundantly with water.
During the bleeding of the braking
circuit keep the handlebar turned
leftwards. This is the way to lift
the pump tank and to make easier the
bleeding of the braking system.
If the lever stroke gets stretchy
and the braking action results as
poor in the case of falls during com-
petitions, or after repair work in shops,
repeat the bleeding operation described
As the bleeding operation does not
fully eliminate the air inside the
circuit, the small quantity of air re-
maining inside will be eliminated after a
short time of use of the brake. In this case
however, the action of the lever will be
harder and the stroke shorter.
