1. Brake fluid reservoir cover 2. Bolt (× 2)
Observe these precautions:
When checking the brake fluid level, make
sure the top of the brake fluid reservoir is
level.
Use only the designated quality brake fluid,
otherwise, the rubber seals may deterio-
rate, causing leakage and poor brake per-
formance.
Refill with the same type of brake fluid. Mix-
ing fluids may result in a harmful chemical
reaction and lead to poor brake perfor-
mance.
Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of
the fluid and may result in vapor lock.
Brake fluid may deteriorate painted surfac-
es or plastic parts. Always clean up spilled
fluid immediately.
Have a Yamaha dealer check the cause if
the brake fluid level goes down.
