Periodic Maintenance Procedures
Front Brake Fluid Change
•
Remove the reservoir cap and the rubber cap on the bleed
valve.
•
Attach a clear plastic hose to the bleed valve on the
caliper, and run the other end of the hose into a con-
tainer.
•
Fill the reservoir with new brake fluid.
•
Change the brake fluid as follows:
○
Open the bleed valve [A].
○
Apply the brake lever and hold it [B].
○
Close the bleed valve [C].
○
Release the brake lever [D].
•
Check the fluid level in the reservoir often, replenishing it
as necessary.
NOTE
○
If the fluid in the reservoir runs completely out any time
during fluid changing, air will enter the line, and the sys-
tem must be bled.
•
Repeat this operation until fresh brake fluid comes out into
the plastic hose or the color of the fluid changes.
WARNING
Do not mix two brands of fluid. Change the brake
fluid in the brake line completely if the brake fluid
must be refilled but the type and brand of the brake
fluid that is already in the reservoir are not known.
•
Tighten:
Torque - Bleed Valves: 7.8 N·m (0.80 kgf·m, 69 in·lb)
•
Apply the brake l ever forcefully for a few seconds, and
check for fluid leakage around the fittings.
If necessary, bleed the air from the brake line (see Brake
Line Air B leeding section in the Brakes chapter).
WARNING
If the brake lever has a soft or “spongy feeling”
when it is applied, there might be air in the brake
line or the brake may be defective. Since it is dan-
gerous to operate the vehicle under such condi-
tions, bleed the air from the brake line immediately.

Dust Cover Replacement
