Changing The Brake And Ycc-S Clutch Fluids - Yamaha FJR1300AS 2017 Owner's Manual

Periodic maintenance and adjustment
 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 or dust
does not enter the brake or
YCC-S clutch fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock, and dirt may clog the ABS
hydraulic unit valves.
NOTICE
Brake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.

The brake and YCC-S clutch fluid res-
ervoir diaphragms will lose their shape
from the negative pressure if the fluid
level goes down too far. Be sure to re-
turn the diaphragms to their original
shape before reinstalling them.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. A low
YCC-S clutch fluid level may indicate
YCC-S clutch system leakage; there-
fore, be sure to check the YCC-S
clutch system for leakage. If the brake
or YCC-S clutch fluid level goes down
suddenly, have a Yamaha dealer check
the cause before further riding.
Changing the brake and
YCC-S clutch fluids
Have a Yamaha dealer change the
brake and YCC-S clutch fluids at the
intervals specified in the periodic main-
tenance and lubrication chart. In addi-
tion, have the oil seals of the brake and
YCC-S clutch master cylinders and
calipers as well as the brake and
YCC-S clutch hoses replaced at the in-
tervals listed below or whenever they
are damaged or leaking.
