Checking the brake fluid level
Insufficient brake fluid may let air enter the brake
system, possibly causing the brakes to become in-
effective.
Before riding, check that the brake fluid is above
the minimum level and replenish when necessary.
A low brake fluid level may indicate worn brake
pads and/or brake system leakage. If the brake flu-
id level is low, be sure to check the brake pads for
wear and the brake system for leakage. The rear
brake fluid master cylinder reservoir is located be-
hind panel B. (See page 8-23 for panel removal
and installation procedures.)
Observe these precautions:

When checking the fluid level, make sure the
top of the master cylinder reservoirs are level.


Use only the designated quality brake fluid, oth-
erwise the rubber seals may deteriorate, caus-
ing leakage and poor brake performance.
Recommended brake fluid: DOT 4
