322 SERVICING AND MAINTENANCE
Fluid Level Check — Brake Master
Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
Brake System Warning Light is on. If necessary, add
fluid to bring level within the designated marks on the
side of the reservoir of the brake master cylinder. Be
sure to clean the top of the master cylinder area before
removing cap. With disc brakes, fluid level can be
expected to fall as the brake pads wear. Brake fluid
level should be checked when pads are replaced. If the
brake fluid is abnormally low, check the system for
leaks.
For further information page 363.
WARNING!
•
Use only manufacturer recommended brake fluid
page 363. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the origi-
nal factory installed hydraulic master cylinder
reservoir.
•
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from
the air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
•
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
•
Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake fail-
ure. This could result in a collision.

FRONT/REAR AXLE FLUID

For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected, inspect the
fluid level.
Fluid Level Check
Lubricant should be approximately 1/8 inch (3 mm)
below the bottom edge of the oil fill hole.
NOTE:
Make sure that the vehicle is level and supported by
the axles.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Selection Of Lubricant
(Continued) Use only the manufacturer's recommended fluid
