Changing The Brake Fluid - Yamaha YFZ 2018 Owner's Manual

TIP
To check the rear brake fluid level, remove the
seat. (See page 4-10.)
Specified brake fluid:
DOT 4
EWB02721
WARNING
Improper maintenance can result in loss of
braking ability. Observe these precautions:
 Insufficient brake fluid may allow air to enter
the brake system, reducing braking perfor-
mance.
 Clean the filler cap before removing. Use
8
only DOT 4 brake fluid from a sealed contain-
er.
 Use only the specified brake fluid; otherwise,
the rubber seals may deteriorate, causing
leakage.
 Refill with the same type of brake fluid. Add-
ing a brake fluid other than DOT 4 may result
in a harmful chemical reaction.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Water will
significantly lower the boiling point of the flu-
id and may result in vapor lock.
ECB01161
NOTICE
Brake fluid may damage painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.
As the brake pads wear, it is normal for the brake
fluid level to gradually go down. A low brake fluid
level may indicate worn brake pads and/or brake
system leakage; therefore, be sure to check the
brake pads for wear and the brake system for
leakage. If the brake fluid level goes down sud-
denly, have a Yamaha dealer check the cause be-
fore further riding.
