refers to the front disc brake only.
The following information may refer to just

CHECKING THE SYSTEM
NOTE
Carry out these checks only on a
firm, flat surface such as a concrete garage
floor.
◆
Place the vehicle on the center stand.
MIN = minimum level.
◆
Rotate the handlebar, so that the fluid
contained in the brake reservoir (1) is
parallel to the “
MIN ” mark stamped on
the glass gauge (2), if not, level lines in
the reservoir will give an inaccurate indi-
cation.
◆
Ensure that the fluid contained in the res-
ervoir exceeds the “ MIN ” mark stamped
on the glass gauge (2).
If the fluid does not reach the “MIN”
mark:
a
CAUTION
When the disc pads wear out, the level
of the fluid decreases progressively to
compensate for their wear.
◆
Check the front brake pad wear, p. 66
(CHECKING THE BRAKE PAD WEAR)
and the front disc wear.
If the pads and/or the disc do not need
replacing:
◆
Top up the reservoir, see below (TOP-
PING UP) .
TOPPING UP
Carefully read p. 37 (BRAKES) and p. 38
(DISC BRAKES).
◆
Remove the front handlebar cover, see
p. 72 (REMOVING THE FRONT HAN-
DLEBAR COVER).
a
CAUTION
To remove the two screws (3) which
hold the reservoir cover (4) in place, the
handlebar must be rotated so that the
fluid contained in the brake reservoir is
parallel to the “MIN” mark stamped on
the glass gauge (2).
If not, brake fluid will spill from the res-
ervoir.
◆
Rotate the handlebar so that the fluid
contained in the brake reservoir is paral-
lel to the “MIN” mark stamped on the
glass gauge (2).
