PERIODIC MAINTENANCE AND MINOR REPAIR
6-19
6indicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22540
Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to dis-
assemble the brake. To check the
brake shoe wear, check the position of
the wear indicator while applying the
brake. If a brake shoe has worn to the
point that the wear indicator reaches
the wear limit line, have a Yamaha
dealer replace the brake shoes as a
set.
EAU37001
Checking the front brake fluid
level Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
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
the brake pads for wear and the brake
system for leakage.
Observe these precautions:


When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.


Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
NOTE:If DOT 4 is not available, DOT 3 can beused.

Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.


Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.

lows.
1. Turn the key to “OFF” and turn off
all electrical circuits.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
CAUTION:
ECAT1061


Do not use a fuse of a higher
amperage rating than recom-
mended to avoid causing exten-
sive damage to the electrical
system and possibly a fire.


After removing and installing
the main fuse, be sure to turn
the main switch from “ON” to
“OFF” three times in 3 seconds
intervals to initialize the idlespeed control system.
3. Turn the key to “ON” and turn on
the electrical circuits to check if the
devices operate.
