Braking system
FRICTION GASKETS AND CHECK THAT THEY ARE NOT OILY OR GREASY, SPECIALLY AFTER
MAINTENANCE OPERATIONS OR CHECKS. CHECK THAT BRAKE PIPES ARE NOT TWISTED
OR WORN. PAY UTMOST ATTENTION THAT NO WATER OR DUST INADVERTENTLY GETS INTO
THE CIRCUIT. IT IS ADVISABLE TO WEAR LATEX GLOVES WHEN SERVICING THE HYDRAULIC
CIRCUIT. BRAKE FLUID MAY CAUSE IRRITATION IF IN CONTACT WITH SKIN OR EYES. RINSE
CAREFULLY ALL BODY PARTS THAT HAVE COME INTO CONTACT WITH THE FLUID. SHOULD
THE FLUID COME INTO CONTACT WITH YOUR EYES, SEEK MEDICAL ADVICE OR CONTACT
AN EYE SPECIALIST. DO NOT DISPOSE OF THE FLUID INTO THE ENVIRONMENT. KEEP OUT
OF THE REACH OF CHILDREN WHEN USING BRAKE FLUID, PAY ATTENTION NOT TO SPILL
IT ONTO PLASTIC OR PAINTED COMPONENTS AS IT WILL IRREPARABLY DAMAGE THEM.
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 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 front brake calliper bleed valve and
slide the other end of this pipe in a con-
tainer to collect the fluid.
•
Quickly press and release the front
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-
tainer. This will release tension on the
brake lever and will make it go to the
end of stroke.
•
Close the bleed valve before the lever
reaches its end of stroke.
