Braking system

Remove the brake pads
Bleeding the braking system
Front
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 "sponginess" of the brake control and by 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.
NOTE
THE VEHICLE MUST BE ON LEVEL GROUND TO BE PURGED. WHILE PURGING THE HYDRAUL-
IC SYSTEM, FILL THE RESERVOIR WITH THE NECESSARY QUANTITY OF BRAKE FLUID.
CHECK THAT, DURING THE OPERATION, THERE IS ALWAYS BRAKE FLUID IN THE RESER-
VOIR.
The bleeding procedure can be performed in a traditional way or using specific tools such as vacuum
pumps or similar.
In the following is shown the "traditional" bleeding procedure.
•
Remove the rubber protection cover
from the bleed valve.
