PERIODIC MAINTENANCE AND MINOR REPAIR
ing it to become ineffective.
EAU36680
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
1
the brake pads for wear and the brake
system for leakage.
NOTE:
The rear brake fluid reservoir is located
under the seat. (See page 3-14.)
Observe these precautions:
G
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
G Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Recommended brake fluid:
DOT 4
G
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
6-20
lead to poor braking performance.
G
Be careful that water or dust does
not enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of the
fluid and may result in vapor lock,
and dirt may clog the ABS hydrau-
lic unit valves.
G
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled
immediately.
G As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
