Refilling front brake fluid reservoir
Loosen screws (1), remove cover (2)
and membrane. Place hand brake
cylinder in a horizontal position and fill
the brake fluid reservoir up to the MAX
mark with clean brake fluid DOT 4.
Replace membrane, lid and tighten
screws. Clear off spilled or overflowing
brake fluid with water.
!
CAUTION !
Don’t let brake fluid get in contact
with paint; it is an effective paint
remover.
Use only clean brake fluid from a
sealed
or hermetic closed
container.
!
CAUTION
!
Do not remove front or rear brake
cover while handlebar is not in a
position where reservoir is leveled
and motorcycle vertical.
Avoid actuate brake lever with cover
removed. Brake fluid will spill over if
lever is actuated.
Do not mix different fluids, once they
can be incompatible.
Avoid spill fluid over painted parts,
plastic or rubber. Place a cover over
those parts whenever braking system
is under maintenance.
Checking front brake pads
The front brake pads can be inspected
from below. The linings must have at
least 1 mm thickness.
! WARNING !
At their most worn point brake pad
linings should not be thinner than
1mm, otherwise can lead to braking
failure.
! WARNING !
If brake pads are replaced too late
so that the lining is partly or entirely
worn, steel components of brake
pad will rub against brake disc,
thereby reducing braking effect and
destroying brake disc.
Replacing front brake pads
Remove calliper assembly, unscrewing
screws (1).
Press the brake calliper away from
brake disc to put the brake piston in its
basic position. Remove clips and the
brake pads from the calliper.
