Air Chamber Stroke Indication
Air chamber push rods have orange stroke indicator markers that warn
when the braking system requires adjustment or repair. The orange
stripe is painted on the air chamber push rod at the slack adjuster stroke
dimension which requires service when visible during brake application.
Air brake inspection and adjustment or repairs should be performed by a
qualified service technician in accordance with the instructions in the
service manual.
Cam Brakes - Automatic Slack Adjusters
WARNING:Do not manually adjust the automatic slack adjusters
to correct excessive push rod stroke as it may result in reduced
brake effectiveness and a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the
installation of the adjuster, or with foundation brake components that
manual adjustment does not remedy. Seek service from a qualified
facility for excessive push rod stroke.
Standard air brakes (cam) are
equipped with automatic brake
adjusters. Automatic adjustment
occurs during brake applications.
Inspect brakes for proper
adjustment at the intervals listed in
theScheduled Maintenance
chapter.
Emergency Air Brake
WARNING:Do not continue to operate the vehicle with a failure
of one of the brake systems. Take the vehicle to your dealer for
service immediately.
All vehicles are equipped with a dual brake system. In the unlikely event
of a failure of one system, the second system functions for emergency
stopping. These systems are all controlled by the brake pedal in the
same manner as for normal stops.

Air Brakes
WARNING:Do not manually adjust the automatic slack adjusters
to correct excessive push rod stroke as it may result in reduced
brake effectiveness and a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the
installation of the adjuster, or with foundation brake components that
manual adjustment does not remedy. Seek service from a qualified
facility for excessive push rod stroke.
Inspection and adjustment:Establish a regular schedule for periodic
cleaning, lubrication and adjustment inspection based on vehicle use.
Exact maintenance intervals are difficult to predetermine since vehicles
are used in a wide variety of applications and conditions. If you are
uncertain of the proper schedule for your vehicle, contact your dealer.
Regular inspections should include:
•periodic checking (every service interval) of push rod travel or brake
adjustment. This is essential for effective braking. Brake chamber
push rods on original equipment chambers now incorporate an orange
paint marker near the base of the push rod as a stroke indicator to
aid in adjustment checks. If the push rod is clean and the brakes are
out of adjustment, the orange marker can be seen protruding from
the chamber when the brakes are applied.
•checking the brake lining (every service interval). When brake lining
or blocks are worn to within 1/16th inch (1.6 millimeters) of rivets,
replace the brake linings. This inspection or adjustment should only
be performed by a qualified technician and must be in accordance
with instructions provided by the service manual.
Do not back off or disconnect the front brakes so that they are less
effective, letting the rear brakes do all the stopping of the vehicle. Do
not overlook the brakes on the trailer either. Brake condition on the
trailer is just as important as the tractor. Proper brake balance on trucks
and tractor-trailers is essential for effective braking.
Once a year, the entire brake system must be inspected:
•Rubber components for deterioration. These components should be
inspected by a qualified technician and replaced as necessary.
Replacement intervals vary according to the severity and length of
vehicle service.
•Condition of brake drums, brake chambers and slack adjusters.
•System for air leaks.
•Hose or pipes for rust, damage and deterioration.
•Operation of service and parking brakes.

Some parts such as air brake chamber diaphragm, air compressor and air
cleaner should be inspected periodically and replaced if considered
unserviceable.
Air dryer:Climactic conditions affect performance of desiccant or
after-cooler type air dryers. Maintenance schedules must be established
for each specific operation.
The use of an air dryer on a vehicle does not eliminate the need to
periodically drain the air reservoirs.
Desiccant air dryer:Inspect for moisture in the air system by opening
reservoirs, draincocks or valves and checking for presence of water. The
presence of small amounts of water due to condensation is normal and
should not be considered as an indication that the dryer is not
functioning properly.
The desiccant cartridge should be replaced or rebuilt when it has been
determined that the desiccant is contaminated and does not have
adequate water absorption capacity. The desiccant change interval may
vary. It is generally recommended that the desiccant be replaced every
12 months (yearly). If experience has shown that extended or shortened
life has resulted for a particular installation, then the yearly interval can
be increased or decreased accordingly.
Draining the air brake reservoir:
Completely drain all the air brake
reservoirs daily by opening the
draincock at the ends of the tanks
(Where accessible. Pull-chains are
used when the drains are undercab
or otherwise inaccessible). Close the
draincock after draining. Air tanks
equipped with automatic moisture
ejector valves may also be drained
manually as required to maintain a
dry air system. Contact your dealer if you are unsure of the air reservoir
locations or the draining procedure.
WARNING:Failure to drain air brake reservoirs can result in a
reduction or loss of braking ability due to fluid accumulation in
the reservoir and/or possible freeze-up during cold weather.

Hydraulic Brakes
Establish a regular schedule for periodic cleaning, lubrication and
adjustment inspection based on vehicle use. Exact maintenance intervals
are difficult to predetermine since vehicles are used in a wide variety of
applications and conditions. If you are uncertain of the proper schedule
for your vehicle, contact your dealer.
Regular inspections should include:
•checking the brake lining (every service interval). Establish
inspection intervals that provide for lining replacement before damage
to the disc occurs. Excessive lining wear may expose the backing
plate to the disc causing scoring of the disc faces. This inspection
should be performed by a qualified technician and must be in
accordance with instructions provided by the service manual.
Hydraulic brake systems are power-assisted. Braking capabilities are
greatly reduced without engine assist.
•proper fluid level. The level should be at the bottom edge of the ring
on each reservoir fill port. Do not fill the master cylinder to the top of
the reservoir. If fluid level requires attention to maintain a proper
master cylinder level, this is an indication of either severe operation
(pad wear) or fluid leakage. A more frequent and thorough brake
inspection is required.
•brake lines, hoses and fittings. Repair or replace brake line tubes,
hoses or fittings as required. Inspect these components every
4000 miles (6000 kilometers):
•Lines for kinks, dents, corrosion or rupture.
•Hoses for abrasions, kinks, soft spots or rupture, collapse, cracks,
twists or loose frame supports. When replacing a hose, be sure
there is adequate clearance to the hose to avoid an abrasion to the
new hose.
•All connections for leaks.
Driveline Parking Brake
WARNING:Use wheel chocks and exercise caution when
inspecting under the vehicle. A vehicle roll-away could result in
property damage, personal injury or death.
Parking brake adjustment should only be performed by a qualified
technician, and in accordance with the instructions in the service
manual.

GENERAL MAINTENANCE INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance schedule helps protect against major
repair expenses resulting from neglect or inadequate maintenance and
may help to increase the value of your vehicle when you sell or trade it.
Keep all receipts for completed maintenance with your vehicle.
We have established regular maintenance intervals for your vehicle based
upon rigorous testing. It is important that you have your vehicle serviced
at the proper times. These intervals serve two purposes; one is to
maintain the reliability of your vehicle and the second is to keep your
cost of owning your vehicle down.
It is your responsibility to have all scheduled maintenance performed and
to make sure that the materials used meet the specifications identified in
theCapacities and Specificationschapter of this owner’s manual.
Failure to perform scheduled maintenance invalidates warranty coverage
on parts affected by the lack of maintenance.
Protecting Your Investment
Maintenance is an investment that pays dividends in the form of
improved reliability, durability and resale value. To maintain the proper
performance of your vehicle and its emission control systems, make sure
you have scheduled maintenance performed at the designated intervals.
Your vehicle is very sophisticated and built with multiple, complex,
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That is why it is
important to rely upon your dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
We strongly recommend the use of only genuine Ford, Motorcraft or
Ford-authorized re-manufactured replacement parts engineered for your
vehicle.
