Checking The Brake Fl Uid Level - Yamaha YW50FD Owner's Manual

Checking the brake fl uid level
1. Minimum level mark
Before riding, check that the brake
fl uid is above the minimum level mark.
Check the brake fl uid level with the
top of the reservoir level. Replenish
the brake fl uid if necessary.
Specifi ed brake fl uid:
DOT 4
WARNING
Improper maintenance can result
in loss of braking ability. Observe
these precautions:
● Insuffi cient brake fl uid may al-
low air to enter the brake sys-

tem, reducing braking perfor-
mance.
● Clean the fi ller cap before re-
moving. Use only DOT 4 brake
fl uid from a sealed container.
●
Use only the specifi ed brake

fl uid; otherwise, the rubber
seals may deteriorate, causing
leakage.
● Refi ll with the same type of
brake fl uid. Adding a brake fl u-
id other than DOT 4 may result
in a harmful chemical reaction.
●
Be careful that water does not
enter the brake fl uid reser-
voir when refi lling. Water will
signifi cantly lower the boiling
point of the fl uid and may re-
sult in vapor lock.
NOTICE
EWA15990
Brake fl uid may damage painted
surfaces or plastic parts. Always
clean up spilled fl uid immediately.
As the brake pads wear, it is normal
for the brake fl uid level to gradually
go down. A low brake fl uid 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
fl uid level goes down suddenly, have
a Yamaha dealer check the cause be-
fore further riding.
