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 FOLLOWING OPERATIONS REFER TO ONLY ONE FRONT BRAKE CALLIPER BUT APPLY
TO BOTH CALLIPERS. 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 front brake calliper bleed valve and
slide the other end of this pipe in a con-
tainer to collect the fluid.
•
Remove the front brake oil reservoir
cap.
•
Operate the brake lever and then open
the bleed valve on the calliper 1/4 of a
turn to let the air out.
•
Close the bleed again before reaching
the lever end of the stroke and repeat
the operation until there is no air.
•
Repeat the procedure for both callip-
ers.
•
Screw the bleeding valve and remove
the pipe.
•
Top-up the reservoir until the correct
brake fluid level is obtained.
•
Refit and block the front brake oil res-
ervoir cap.
•
Refit the rubber protection cover.
