•
Refit and block the front brake oil reservoir cap.
•
Refit the rubber protection cover.
Integrated
Any air trapped in the hydraulic circuit acts as a
cushion, absorbing much of the pressure applied
by the brake pump and minimising the braking
power of the calliper.
The presence of air is signalled by the "spongi-
ness" of the brake control and poor braking effi-
ciency.
CAUTION
CONSIDERING THE DANGER FOR VEHICLE AND RIDER,
IT IS STRICTLY NECESSARY, AFTER REFITTING BRAKES
AND RESTORING THE BRAKING SYSTEM TO THE REGU-
LAR USE CONDITIONS, THAT THE HYDRAULIC CIRCUIT
BE AIR PURGED.
THE VEHICLE MUST BE ON LEVEL
GROUND TO BE PURGED. WHILE PURGING THE HY-
DRAULIC SYSTEM, FILL THE RESERVOIR WITH THE NEC-
ESSARY QUANTITY OF BRAKE FLUID. CHECK THAT,
DURING THE OPERATION, THERE IS ALWAYS BRAKE
FLUID IN THE RESERVOIR.
•
Remove the rubber protection cover
from the bleed valve.
•
Insert the transparent plastic pipe in
the rear brake calliper bleed valve and
insert the other end of this pipe into a
container to collect the fluid.
•
Remove the rear brake fluid reservoir
cap.
•
Press the rear brake pedal to the bot-
tom, then release it and wait some sec-
onds before performing the following
pumping.
•
Loosen the bleed valve 1/4 of a turn so
that the brake fluid flows into the con-
tainer. This will release the tension on
the rear brake pedal and will make it
reach the end of stroke.
•
Close the bleed valve before the rear
brake pedal reaches its end of stroke.
