2013 FORD F650 brakes

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.

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.

BRAKE FLUID CHECK
WARNING:Brake fluid is toxic. If brake fluid contacts the eyes,
flush eyes with running water for 15 minutes. Seek medical
attention if irritation persists. If taken internally, drink water and induce
vomiting. Seek medical attention immediately.
WARNING:If you use a brake fluid that is not DOT 3, you will
cause permanent damage to your brakes.
WARNING:Do not let the reservoir for the master cylinder run
dry. This may cause the brakes to fail.
Check and refill the Full Power brake fluid reservoir using the following
procedure. See theScheduled Maintenancechapter for the service
interval.
1. Clean the reservoir caps before removal to prevent dirt or water from
entering the reservoir.
2. Visually inspect the fluid level. It should be at the bottom of the fill
ports.
3. Add brake fluid, if necessary, from a clean, unopened container until
the level reaches the bottom of the fill ports. Do not fill above this
line.
Only use a DOT 3 brake fluid certified to meet manufacturer
specifications. See theCapacities and Specificationschapter.
CLUTCH FLUID AND LINKAGE
Clutch Fluid
WARNING:Carefully read cautionary information on product
label. For MEDICAL EMERGENCY INFORMATION, contact a
physician or Poison Control Center immediately; on Ford-Motorcraft®
products call: 1-800-959-3673 (FORD). Failure to follow these
instructions may result in personal injury.
Use only a DOT 3 brake fluid designed to meet manufacturer
specifications. See theCapacities and Specificationschapter.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, fill to the step in the reservoir.

Fuel System
Note:During extended periods of vehicle storage (30 days or more),
fuel may deteriorate due to oxidation. Add a quality gas stabilizer
product to the vehicle fuel system whenever actual or expected storage
periods exceed 30 days. Follow the instructions on the additive label.
The vehicle should then be operated at idle speed to circulate the
additive throughout the fuel system.
•Fill the fuel tank(s) with high-quality fuel until the first automatic
shutoff of the fuel pump nozzle.
Cooling System
•Protect against freezing temperatures.
•When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.

Rotating tires from one wheel position to another is a way often used to
even out many types of irregular wear or to avoid it altogether. Some of
the more effective tire rotation programs are:
•Steer tires that have developed some type of irregular wear pattern
can be rotated to drive axles if rib tires are being used on all wheel
positions. Applying steer tires to a drive position often cleans them
and they can be moved back to the steer axles or run out to re-tread
stage on the rear axle.
•Another rotation possibility for fleets with rib tires in all wheel
positions is to break in the new steer tires in the drive axle positions,
then move them to steer axles. This wears away tread rubber
relatively quickly in the early life of a tire when it is most likely to
develop an unusual wear pattern.
•Drive axle tires may be placed on the other end of the same axle so
that direction of rotation is reversed. This is often helpful if a heel
and toe or alternate lug wear pattern has developed.
Irregular wear can be minimized by:
•Using the right inflation pressure for the load being carried.
•Maintaining proper front wheel alignment, especially toe-in, to
specifications.
•Maintaining proper tire and wheel balance.
•Maintaining shock absorbers and suspension components.
Use of Tire Chains
See the chain manufacturer’s recommendation for correct tire chain
usage, installation and removal.
WHEELS
General Information
Note:Remember to replace the wheel air valves when the road tires are
replaced at the end of their useful lives.
Wheel bearings should be inspected, lubricated and adjusted at regular
intervals. This is especially important if operating in deep sand, mud or
water. See theCapacities and Specificationschapter.
Mount wheel balance weights on the dome-side of the wheel only. Failure
to do so may result in loss of wheel weight or damage to brakes or
wheels.

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.
Inspect standard air brakes equipped with automatic slack adjusters for
proper brake adjustment as listed in the maintenance schedule charts.
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.
