Combined Brake - PIAGGIO X9 500 cc Service Manual

Braking system
Note: If air keeps coming out during the bleeding,
check all connections. If these are tight, check the
different pump seals and the caliper pistons.
During the operation oil may trickle from the bleeder
screw onto the caliper and the disc. In that case,
carefully dry the caliper and degrease the disc.

Combined brake

A control system allows the left brake lever to
simultaneously operate the left-hand front caliper and
the rear caliper.
To empty the circuit, follow the procedure given for the
right-hand front brake, using the bleeder of both brake
calipers, front and rear.
To bleed the system, follow these steps:
1) Attach the specific Mityvac tool to the bleeder fitted
on the pressure divider valve shown in the figure.
2) Fill the left brake fluid reservoir to the maximum
level.
3) Slowly operate the left brake lever while pouring
fresh fluid into the reservoir until all the air has come
out, thus obtaining the bleeding of the first section
of the combined brake line. Tighten the bleeder
valve with the prescribed torque.
4) Proceed to bleed each caliper - the front caliper first
and then the rear caliper - following the same
procedure used for the front brake.
