Changing The Brake Uid - Yamaha Y16ZR 2021 Owner's Manual

 Use only the speci ed brake u-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
 Re ll with the same type of
brake uid. Adding a brake uid
other than DOT 3 or DOT 4 may
result in a harmful chemical re-
action.
 Be careful that water does not
enter the brake uid reservoir

cantly lower the boiling point of
the uid and may result in vapor

Brake uid may damage painted
surfaces or plastic parts. Always
clean up spilled uid immediately.
As the brake pads wear, it is normal for
the brake uid level to gradually go
down. A low brake uid 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. If the brake
