Checking The Brake Fluid Level; Changing The Brake Fluid - Yamaha Ego Avantiz Owner's Manual

Periodic maintenance and adjustment

Checking the brake fluid level

1. Minimum level mark
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 flu-
id 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.
EAUU0831 Use only the recommended quali-
ty brake fluid, otherwise the rub-
ber seals may deteriorate, causing
leakage and poor braking perfor-
1
mance.
Recommended brake fluid:
YAMAHA GENUINE BRAKE FLUID
or equivalent DOT3 or DOT4
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.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.

Changing the brake fluid

Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the brake master cylinder and cali-
per as well as the brake hose replaced
at the intervals listed below or whenev-
er they are damaged or leaking.
Oil seals: Replace every two
years.
Brake hose: Replace every four
