AIR BRAKE ADJUSTMENT
Failure to maintain proper air brake adjustment can result in
reduction or loss of braking ability.
Air brake inspection and adjustment should be performed by a qualified
service technician in accordance with the instructions in the Ford Truck
Service Manual.
Cam brakes - automatic slack adjusters
Inspect standard air brakes equipped with automatic slack adjusters for
proper brake adjustment every four months or 32 000 km (20 000 miles)
whichever occurs first.
However, more frequent inspection is required if your vehicle’s brakes
are subjected to heavy use or adverse operating conditions such as:
•Frequent brake applications while fully loaded.
•Operation on hilly or mountainous terrain.
•Frequent operation on dirt, gravel or mud.
Some aftermarket brake linings also require more frequent inspections.

Inspect the entire exhaust
system (including inlet pipe,
muffler, outlet pipe and all
exhaust clamps and fasteners)
for holes, leakage, breakage,
looseness and corrosive
damageExcessive noise or the smell of fumes
is experienced
Inspect the engine air

air ducts, the air cleaner, and
the air cleaner element) for
loose fitting, damaged or
missing componentsExcessive noise emanates from the
engine compartment
Inspect the tires and check the
air pressure (*c)Poor steering, wandering or excessive

Maintenance Operation Frequency - Observation
Check the transmission and
engine mountings (*b)Hard shifting or excessive vibration
Check and adjust transmission
controls (*b)High effort to shift or noisy
transmission
Check fuel pump pressure Insufficient full-throttle power or
backfiring
Clean radiator cap seal. Clean
and inspect the cap surface on
the radiatorWhen the cap does not hold pressure
Check the battery terminals for
corrosionWhenever electrical power supply has
diminished
Tighten the wheel mounting
nuts to the specified torque.
Refer toServicing your
wheels and tiresRequired initially at 804 and 1 609 km
(500 and 1 000 miles). Perform again
at 804 and 1 609 km (500 and 1 000
mile) intervals after each tire
removal/replacement.
*a During maintenance and repair, protect the fuel tube and the hose
assemblies, the power steering lines, and the air brake lines from the
external heat, the acids and the abrasion that could damage the lines.
*b Check for (free) linkage action and ensure that (return) spring
force is adequate to maintain pedal free play.
*c Adjust, repair or replace as required with the same or equivalent
parts.
