FRONT AND REAR BRAKES
CAUTION:
_
Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
brake fluid immediately.
WARNING
_
• Use only the designated quality brake
fluid: other brake fluids may deteriorate
the rubber seals, causing leakage and
poor brake performance.
• Refill with the same type of brake fluid:
mixing brake fluids may result in a harm-
ful chemical reaction and lead to poor
brake performance.
• Be careful that water does not enter the
master cylinder when refilling. Water will
significantly lower the boiling point of the
brake fluid and may result in vapor lock.
