Fluid change
The brake fluid should be checked and changed in accordance with the Periodic
Maintenance Chart (page B.9) or whenever it is contaminated with dirt or water.
Don't change the fluid in the rain or when a strong wind is blowing.
Use only brake fluid from a sealed container (DOT 4). Never use old
brake fluid.
Never allow contaminants (dirt, water, etc.) to enter the brake fluid
reservoir.
Don't leave the reservoir cap off any length of time to avoid moisture
contamination of the fluid.
Handle brake fluid with care because it can damage paint.
Don't mix two types of fluid for use in the brake. This lowers the brake
fluid boiling point and could cause the brake to be ineffective. It may also
cause the rubber brake part to deteriorate.
To replace the fluid, proceed as follows:
- Remove the rubber cap on the bleeding valve (1) or (1A).
- Attach a clear plastic hose to the bleeding valve on the brake caliper and turn
the other end of the hose into a container.
- Remove fluid reservoir cap (2) or (2A, 21 mm wrench) and the rubber.
- Loosen bleeding valve on the brake caliper.
- Pump with brake lever (3) or brake pedal (3A) in order to push brake fluid out
of line.
- Close the bleeding valve and fill the reservoir with fresh brake fluid.
- Open the bleeding valve, apply the brake using the brake lever or pedal, close
the bleeding valve with the brake lever or pedal applied and then quickly release
the lever or pedal.
- Repeat this operation until the brake line is filled and clear fluid starts coming
out of the plastic hose: now close the bleeding valve.
- Restore the brake fluid level (A) or (B) then reassemble the rubber and the
fluid reservoir cap.
After the brake fluid replacement, it is necessary to operate the braking sys-
tem
bleeding.
