hardware are described in detail in the Antilock
Brake System section.
The parking brake on this vehicle is pedal-oper-
ated.
For more information on the description of any
individual base brake component, refer to that com-
ponent elsewhere in this section. For information on

OPERATION - BASE BRAKES
When a vehicle needs to be stopped, the driver
applies the brake pedal. The brake pedal pushes the
input rod of the power brake booster into the booster.
The booster uses vacuum to ease pedal effort as force
is transferred through the booster to the master cyl-
inder. The booster's output rod pushes in the master
cylinder's primary and secondary pistons applying
hydraulic pressure through the chassis brake tubes,
junction block, and proportioning valves to the
brakes at each tire and wheel assembly.
The pedal-operated parking brake operates in the
following manner. When applied, the parking brake
lever pulls on cables that actuate parking brake
shoes at each rear wheel.
For more information on the operation of any indi-
vidual base brake component, refer to that compo-
nent elsewhere in this section.
WARNING
WARNING: DUST AND DIRT ACCUMULATING ON
BRAKE PARTS DURING NORMAL USE MAY CON-
TAIN ASBESTOS FIBERS FROM PRODUCTION OR
AFTERMARKET BRAKE
EXCESSIVE CONCENTRATIONS
FIBERS CAN CAUSE SERIOUS BODILY HARM.
EXERCISE CARE
PARTS. DO NOT SAND OR GRIND BRAKE LINING
UNLESS EQUIPMENT USED IS DESIGNED TO CON-
TAIN THE DUST RESIDUE. DO NOT CLEAN BRAKE
PARTS WITH COMPRESSED AIR OR BY DRY
BRUSHING. CLEANING SHOULD BE DONE BY
DAMPENING THE BRAKE COMPONENTS WITH A
FINE MIST OF WATER, THEN WIPING THE BRAKE
COMPONENTS CLEAN WITH A DAMPENED CLOTH.
DISPOSE OF CLOTH AND ALL RESIDUE CONTAIN-
ING ASBESTOS FIBERS IN AN IMPERMEABLE
CONTAINER WITH THE APPROPRIATE LABEL. FOL-

WHEN SERVICING
CAUTION
CAUTION: Use only Mopar brake fluid or an equiv-
alent from a tightly sealed container. Brake fluid
must conform to DOT 3 specifications. Do not use
petroleum-based fluid because seal damage in the
brake system will result.
LAMP
CAUTION: Brake fluid will damage painted surfaces.
If brake fluid is spilled on any painted surfaces,
wash it off immediately with water.
CAUTION: Never use gasoline, kerosene, alcohol,
motor oil, transmission fluid, or any fluid containing
mineral oil to clean system components. These flu-
ids damage rubber cups and seals.
CAUTION: During service procedures, grease or
any other foreign material must be kept off the cal-
iper assembly, brake linings, brake rotor and exter-
nal surfaces of the hub.
CAUTION: When handling the brake rotor and cali-
per, be careful to avoid damaging the brake rotor
and caliper, and scratching or nicking the brake
shoe lining.
CAUTION: If the vehicle is equipped with the Tire
Pressure Monitoring (TPM) System, the tire/wheel
assembly needs to be reinstalled in the same loca-
tion it is removed from or the TPM System (sen-
sors) will need to be retrained. Mark each tire/wheel
assembly indicating location, prior to its removal. If
the tire/wheel assemblies are switched, rotated or
replaced, the TPM System needs to be retrained.
