Brake System - Jeep Grand Cherokee Owner's Manual

Brake System

In order to assure brake system performance,
all brake system components should be peri-
odically inspected. Refer to the "Maintenance
Schedule" in Section 8 for the proper mainte-
nance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly an accident. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
Fluid Level Check – Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood ser-
vice, or immediately if the brake system warn-
ing lamp indicates system failure.
The brake master cylinder has a translucent
plastic reservoir. On the outboard side of the
reservoir, there is a "MAX" dot and a "MIN" dot.
The fluid level must be kept within these two
dots. Do not add fluid above the MAX mark,
because leakage may occur at the cap.
With disc brakes, the fluid level can be ex-
pected to fall as the brake linings wear. How-
ever, an unexpected drop in fluid level may be
caused by a leak and a system check should
be conducted.
Refer to "Fluids, Lubricants, and Genuine
Parts" in this section for the correct fluid type.
WARNING!
• Use only manufacturer's recommended
brake fluid. Refer to "Fluids, Lubricants,
and Genuine Parts" in this section for the
correct fluid type. Using the wrong type of
brake fluid can severely damage your
brake system and/or impair its perfor-
mance. The proper type of brake fluid for
your vehicle is also labeled on the original
factory installed hydraulic master cylinder
reservoir.
WARNING! (Continued)
• To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed con-
tainer. 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 prolonged braking, resulting in sud-
den brake failure. This could result in a
accident.
• 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 con-
taminate the brake fluid. Brake seal com-
ponents could be damaged, causing partial
or complete brake failure. This could result
(Continued)
in an accident.
