FLUID
SPECIFICATION

Power brake systems require MOP AR®Heavy-D uty
Brake Fluid, or an equivalent product identified with
FMVSS No. 116, DOT-3 and SAE J-1703 Standard designations. Use fresh brake fluid only when adding fluid to the
reservoir. Never use reclaimed fluid, fluid that does not conform to the DOT/SAE Standards, or fluid from a container that has been left open.

CAUTION:
Use of a
brake fluid that
has a
lower ini­

tial
boiling point then specified
by
FMVSS
No. 116
or
DOT 3
could result
in
sudden brake failure dur­
ing
hard, prolonged braking.

CAUTION:
Do not
allow petroleum base
fluids
to

contaminate
the
brake fluid. Seal damage
will
re­

sult.
BRAKE SYSTEM INSPECTION (1) Inspect the brake pads and linings for excessive
wear, cracks and broken rivets.
(2) Inspect brake pads and linings for contamina­
tion with brake fluid, axle lubricant and/or other flu­
ids.

(3) Replace the front brake pads and the rear
brake linings if they are worn to within 0.78 mm (1/32 in) of a rivet head.
(4) Operate the rear brake self-adjuster lever and
pivot. Test the operation of the self-adjuster screw for ease of movement. (5) Inspect the self-adjuster components for frayed
cables, loose or overheated springs, and a binding
condition.
(6) Inspect the caliper dust boots for damage/tears
and indications of brake fluid leakage. Inspect the
bushings and pins for corrosion, tears and a binding condition.
(7) Inspect the rear wheel cylinder dust boots for
fluid leaks. Inspect the pistons and cylinder bores for
proper appearance. (8) Inspect the brake differential warning valve
and housing for indications of leakage, kinked hoses and loose fittings.

BRAKE
FLUID
HOSES/TUBING
The rubber brake fluid hoses should be inspected
for:
• Correct length
• Severe surface cracking
• Swelling
• Pulling
• Scuffing
• Excessively worn areas If the hose fabric casing is exposed either by
cracks or abrasions in the rubber cover, the
hose should be replaced.
Faulty brake fluid hose installation can cause
twisting, and wheel/tire or chassis interference.
(1) Inspect all the hoses for kinks, a distorted con­
dition and fluid leakage. (2) Inspect the hose and tubing routing under the
vehicle. Verify that no hose/tubing is rubbing against any exhaust system or other underbody components.

PARKING
BRAKE
LUBRICATION
The pivot and sliding contact areas of the parking
brake ratio lever should be lubricated to maintain ease of operation (Fig. 5).
(1) Apply MOPAR®Spray White Lube or equiva­
lent to the sliding contact areas.
(2) Lubricate the control lever pivot areas with en­
gine oil.

PARKING
BRAKE
FUNCTIONAL
TEST
AND
INSPECTION
(1) Engage the parking brake pedal and then re­
lease it. (2) Test it for smooth operation and vehicle-hold­
ing capability.
(3) Inspect the parking brake cables for kinks,
fraying and a binding condition. (4) With the parking brake released, the rear
wheels should rotate without restriction. Adjust the
parking brake cable tension, if necessary.
(5) Repair any parking brake malfunctions.

vice procedures).

BODY
COMPONENT
MECHANISMS
LUBRICATION REQUIREMENTS
All operating mechanisms and linkages should be
lubricated when necessary. This will maintain ease of operation and provide protection against rust and
excessive wear. The door weatherstrip seals should
be lubricated to prolong their life as well as to im­ prove door sealing.

LUBRICANT SPECIFICATIONS
All applicable exterior and interior vehicle operat­
ing mechanisms should be:
• Inspected • Cleaned
• All the pivoting/sliding contact areas on the mech­ anisms should then be lubricated.
MOPAR®Multi-Mileage Lubricant or an equiva­
lent, should be used to lubricate the mechanisms.
The door weatherstrip seals should be lubricated
with silicone lubricant spray. Refer to the Body Lu­
bricant Specifications chart below for additional lu­
bricant applications.

LUBRICATION
(1) When necessary, lubricate the cab and cargo
box operating mechanisms with the specified lubri­
cants.

(2) Apply silicone lubricant to a cloth and wipe it
on door seals to avoid over-spray that can soil pas­
senger clothing. (3) Before applying lubricant, the component
should be wiped clean. After lubrication, any excess
lubricant should be removed.
(4) The hood latch, latch release mechanism, latch
striker and safety latch should be lubricated periodi­
cally.
(5) The door lock cylinders should be lubricated 2
times each year (preferably autumn and spring): • Spray a small amount of lock cylinder lubricant di­
rectly into the lock cylinder
• Apply a small amount to the key and insert it into
the lock cylinder • Rotate it to the locked position and then back to
the unlocked position several times
• Remove the key. Wipe the lubricant from it with a
clean cloth to avoid soiling of clothing.

TIRES
RECOMMENDED MAINTENANCE
The condition of the tires should be inspected. The
inflation pressures tested/corrected at the same time as the engine oil is changed and the oil filter is re­
placed.
The tires/wheels should be rotated periodically to
ensure even tread wear. The tires/wheels should be
rotated at the first 12 000 km (7,500-miles) interval.
Thereafter, at each 24 000 km (15,000-miles) inter­
val.
INSPECTION
Inspect the tires for excessive wear, damage. Test
the tires for the recommended inflation pressure and adjust the pressure accordingly. Refer to the tire in­
flation pressure decal located on the left door face. Also to Group 22—Tires And Wheels for tire pres­sure charts, tire replacement, and treadwear indica­

tors.

ROTATION
Tires/wheels should be rotated according to the rec­
ommended interval. The first tire/wheel rotation is
the most important for establishing the prevention of uneven tread wear. After rotation, adjust the tire in­
flation pressure to the air pressure recommended on
the decal located on the left door face.
Refer to Group 22—Tires And Wheels for the rec­
ommended method of tire/wheel rotation.

HEADLAMPS

MAINTENANCE SCHEDULE
Every six months check the headlamp beams to en­
sure that the headlamp beams are correctly posi­
tioned.
