Yamaha CRYPTON T105E/SE Owner's Manual page 53

Observe these precautions:
8
When checking the fluid level, make
sure that the top of the master cylin-
der is level by turning the handlebars.
8
Use only the recommended quality
brake fluid, otherwise the rubber seals
may deteriorate, causing leakage and
poor braking performance.
Recommended brake fluid: DOT 4
NOTE:
If DOT 4 is not available, DOT 3 can be
used.
8
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead to
poor braking performance.
8
Be careful that water does not enter
the master cylinder when refilling.
Water will significantly lower the boil-
ing point of the fluid and may result in
vapor lock.
8
Brake fluid may deteriorate painted
surfaces or plastic parts. Always clean
up spilled fluid immediately.
8
As the brake pads wear, it is normal
for the brake fluid level to gradually
go down. However, if the brake fluid
level goes down suddenly, have a
Yamaha dealer check the cause.
