BLEEDING THE BRAKE SYSTEM

FRONT CALLIPER
NOTE Position the scooter so that it is stable and
perfectly level.
• Remove master cylinder reservoir cover (A) (right-hand
side), unscrewing the relative two screws, so that you
can replenish the brake fluid.
• Fill the right-hand brake fluid reservoir to the max. level.
• Remove rubber cap (B) from bleed screw (C) and fit a
rubber tube to recover escaping brake fluid.
• Pull the right-hand brake lever to pressurise the brake
circuit.
• Keeping the lever pulled, loosen the bleed screw to
allow any air in the circuit to escape. Now tighten bleed
screw (C).

• Keep repeating this procedure until brake fluid only flows
out of the rubber recovery tube.
• Replenish the brake fluid level in the reservoir.
While bleeding the brakes ensure that no
brake fluid comes into contact with the
scooter bodywork (risk of damage). In addi-
tion, while bleeding the brake callipers avoid
contamination of brake discs or pads with
brake fluid. Failure to comply with this pre-
scription will have a negative effect on the
efficiency of the brake system.
If the escaping brake fluid continues to con-
tain air bubbles during the bleed operation,
check all unions carefully: if the unions are
perfectly tight, check the gaskets on the
master cylinder and the calliper plungers for
the possible ingress of air.
When performing the bleed operation brake
fluid may leak from the bleed screw and
contaminate the calliper or the disc: In this
case dry the calliper thoroughly and de-
grease the disc.
REAR CALLIPER
• To bleed the rear calliper, follow the procedure out-
lined above, but using the left brake lever.
