the brake lever and will make it reach
the end of stroke.
•
Close the bleed valve before the lever
reaches its end of stroke.
•
Repeat the operation until the fluid
draining into the container is air-bubble
free.
NOTE
WHILE PURGING THE HYDRAULIC SYSTEM, FILL THE
RESERVOIR WITH THE NECESSARY QUANTITY OF
BRAKE FLUID. CHECK THAT, DURING THE OPERATION,
THERE IS ALWAYS BRAKE FLUID IN THE RESERVOIR.
•
Screw the bleed valve and remove the pipe.
•
Top-up the reservoir until the right brake fluid level is obtained.
•
Refit and block the front brake oil reservoir cap.
•
Refit the rubber protection cover.
Rear
If there is air in the hydraulic system, it acts as a bearing, absorbing a large part of the pressure from
the brake pump and minimising calliper efficiency during braking.
The presence of air is signalled by the "sponginess" of the brake control and poor braking efficiency.
CAUTION
CONSIDERING THE DANGER FOR VEHICLE AND RIDER, IT IS STRICTLY NECESSARY, AFTER
REFITTING BRAKES AND RESTORING THE BRAKING SYSTEM TO THE REGULAR USE CON-
DITIONS, THAT THE HYDRAULIC CIRCUIT BE AIR PURGED.
THE VEHICLE MUST BE ON LEVEL
GROUND TO BE PURGED. WHILE PURGING THE HYDRAULIC SYSTEM, FILL THE RESERVOIR
WITH THE NECESSARY 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 oil reservoir
cap.
•
Quickly press and release the rear
brake lever several times and then
keep it fully pressed.
•
Loosen the bleed valve 1/4 of a turn so
that the brake fluid flows into the con-
