Changing The Brake Fluid; Checking The V-Belt - Yamaha Aerox GDR155 Owner's Manual

 Use only the recommended quali-
ty brake fluid, otherwise the rub-
ber seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Recommended brake fluid:
YAMAHA GENUINE BRAKE FLUID
or equivalent DOT3 or DOT4
 Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
 Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
 Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled
immediately.
 As the brake pads wear, it is nor-
mal 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.
