Maintenance and Adjustment
Disc Brake Fluid
Inspect the level of brake fluid in both
reservoirs and change the brake fluid in
accordance with scheduled maintenance
requirements. Use only DOT 4 fluid as
recommended in the Specification section.
The brake fluid must also be changed if it
becomes, or is suspected of having become
contaminated with moisture or any other
contaminants.
Front Brake Fluid Level Inspection
and Adjustment
1. Upper level line
2. Lower level line
The brake fluid level in the reservoirs must be
kept between the upper and lower level lines
(reservoir held horizontal).
To inspect the fluid level, check the level of
fluid visible in the window at the front of the
reservoir body.
To adjust the fluid level, release the cap
screws and detach the cover noting the
position of the sealing diaphragm.
Fill the reservoir to the upper level line using
new DOT 4 fluid from a sealed container.
Refit the cover, ensuring that the diaphragm
seal is correctly positioned between the cap
and reservoir body. Tighten the cap retaining
screws to 1. 5 N m .
Brake fluid is hygroscopic which means it
will absorb moisture from the air.
Any absorbed moisture will greatly reduce
the boiling point of the brake fluid causing
a reduction in braking efficiency.
Because of this, always replace brake fluid
in accordance with scheduled maintenance
requirements.
Always use new brake fluid from a sealed
container and never use fluid from an
unsealed container or from one which has
been previously opened.
Do not mix different brands or grades of
brake fluid.
Check for fluid leakage around brake
fittings, seals and joints and also check the
brake hoses for splits, deterioration and
damage.
Always rectify any faults before riding.
Failure to observe and act upon any of
these items may cause a dangerous riding
condition leading to loss of control and an
accident.
