PIAGGIO X9 Evolution 125 2008 - Brake Bleeding Procedures

Front
- Rest the scooter on its stand on level ground.
- Refill the brake circuit reservoir to the maximum
level with the recommended fluid;
- Connect the bleed fitting to the appropriate tool
pipe (Mityvac manual pump);
- Actuate the tool at the bleed fitting, at the same
time constantly top up the brake reservoir to pre-
vent air being drawn into the system, until no more
air escapes at the bleed fitting:
The operation is finished when only oil comes out
of the bleed screws;
- Close the bleed screw and tighten to the prescri-
bed torque.
N.B.
IF AIR CONTINUES TO COME OUT DURING THE BLEED
OPERATION, EXAMINE ALL THE FITTINGS. IF SAID FIT-
TINGS DO NOT SHOW SIGNS OF BEING FAULTY, LOOK
FOR THE AIR INPUT AMONG THE VARIOUS SEALS ON
THE PUMP AND CALLIPER PISTONS. WHEN CARRYING
OUT THE OPERATION, BRAKE FLUID MAY LEAK FROM
THE BLEED SCREW ON THE CALLIPER AND ON THE
DISC. IN THIS CASE; CAREFULLY CLEAN THE CALLIPER
AND DEGREASE THE BRAKE DISC.
CAUTION
The left brake pump is for the integral braking system and, be-
sides controlling the rear brake calliper, it also controls the front
left calliper. Therefore utmost care must be paid when bleeding
these two callipers.
