FRONT AND REAR BRAKES
4. Fill:
• brake fluid reservoir
(with the specified amount of the rec-
ommended brake fluid)
• Use only the designated brake fluid.
Other brake fluids may cause the rub-
ber seals to deteriorate, causing leak-
age 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 fluid reser-
voir. Water will significantly lower the
boiling point of the brake fluid and
could cause vapor lock.

faces and plastic parts. Therefore,
