WARNING
_
• Use only the designated brake fluid.
Other brake fluids may cause the rubber
seals to deteriorate, causing leakage and
poor brake performance.
• Refill with the same type of brake fluid
that is already in the system. Mixing
brake fluids may result in a harmful
chemical reaction, leading to poor brake
performance.
• When refilling, be careful that water does
not enter the brake master cylinder reser-
voir. Water will significantly lower the
boiling point of the brake fluid and could
cause vapor lock.
CAUTION:
_
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
NOTE:
_
In order to ensure a correct reading of the
brake fluid level, make sure the top of the
brake master cylinder reservoir is horizontal.
