98Use only the designated quali-
ty brake fluid. Otherwise, the
rubber seals may deteriorate,
causing leakage and poor
brake performance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
8Refill with the same type of
brake fluid. Mixing fluids may
result in a harmful chemical
reaction and lead to poor
brake performance.
8Be careful that water does not
enter the master cylinder when
refilling. Water will significant-
ly lower the boiling point of
the fluid and may result in
vapor lock. Recommended brake fluid:
