FRONT BRAKING SYSTEM BLEEDING
The braking system must be bled after the fluid replacement or when, due to air in
the circuit, the lever stroke is long and spongy.
Proceed as follows:
- Remove the rubber cap on the bleeding valve (1).
- Attach a clear plastic hose to the bleeding valve on the brake caliper and turn the
other end of the hose into a container (make sure that the end of the hose is sub-
merged in brake fluid during the entire bleeding operation).
- Remove fluid reservoir cap (2), the rubber and fill the reservoir with fresh brake
fluid.
- Open the bleeding valve and pump with brake lever (3) several 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 reser-
voir cap (2).
WARNING!
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 corrosive substance, in the case it comes in con-
tact 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 competitions, or after
repair work in shops, repeat the bleeding operation described above. As the
bleeding operation does not fully eliminate the air inside the circuit, the small
quantity of air remaining 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 stro-
ke shorter.
