BLEEDING THE BRAKE CALIPER
NOTE
Do not work on both braking systems at the
same time. The operations refer to a single braking sys-
tem, but are valid for both (with the differences indicated).
For the front braking system, the operations described
should be carried out on both brake calipers.
Do not remove the two front brake calipers at the same
time.
N
Only for the front braking system. Partially remove
the front brake caliper, see 7.5.5 (REMOVING THE
FRONT BRAKE CALIPERS).
N
For the rear braking system only. The rear brake cal-
iper has already been removed during the bleeding of
the system.
N
Make sure that the transparent pipe (10) is connected
to the bleeder valve (5) and that the free end of the pipe
is into the container (11).
a
CAUTION
Do not use tools (screwdrivers, punches, etc.) that
may damage the pads.
Proceed with care, in order not to damage the brake
pads.
N ✖
Open the brake pads (13) (Pos.A) and keep them in
this position by means of a fork spanner (12).
a
CAUTION
Before releasing the brake pads, tighten the bleeder
valve (5) to prevent air from getting into the hydraulic
circuit.
N ✖
Loosen the bleeder valve (5) and tighten it when a
small quantity of brake fluid (sufficient to verify the
presence of air bubbles) has flown out of the same.
If air bubbles can be noticed in the brake fluid:
a
CAUTION
Clean and degrease the metal spacer (14), in order to
avoid dirtying the brake pads.
N
Position a metal spacer (14) having the same thickness
as the brake disc between the brake pads.
N
Pull the brake lever (9) (for the front brake, or the brake
pump rod for the rear brake) until feeling the presence
of pressure in the system.
a
CAUTION
Make sure that the brake fluid level is always includ-
ed between the MIN and MAX marks; otherwise, pro-
vide for topping up.
N
Repeat the operations marked with "
If no air bubbles can be noticed in the brake fluid:
The bleeding of the brake caliper has been carried out
correctly.
a
CAUTION
Clean the transparent pipe (for its whole length) and
the bleeder valve, removing any residue of brake flu-
id.
