• 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 and brake fluid reservoir. Water will
significantly lower the boiling point of the
brake fluid and could cause vapor lock.
