• Use only the designated quality brake
fluid: other brake fluids may deteriorate
the rubber seals, causing leakage and

mixing brake fluids may result in a harm-
ful reaction and lead to poor brake perfor-
mance.
• Be careful that water does not enter the
brake master cylinder when refilling.
Water will significantly lower the boiling
point of the brake fluid and may result in
vapor lock.
