Checking The Brake Fluid Level - Yamaha YZF-R1 Owner's Manual

Checking the brake fluid level

Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the res-
ervoir in an upright position. Replenish
the brake fluid if necessary.
Specified brake fluid:
DOT 4
NOTICE
Brake fluid may damage painted sur-

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 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
suddenly, have a Yamaha dealer
check the cause before further rid-
ing.
WARNING
Improper maintenance can result in
loss of braking ability. Observe

Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing
performance.
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
Refill with the same type of
brake fluid. Adding 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 signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
