Brakes - Ford F-650 Owner's Manual

Driving
WARNING: Do not drive with your foot resting on the brake
pedal. This results in abnormally high brake temperatures,
excessive lining wear and increased stopping distances.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes. Normally, choose the same gear to
descend the hill that you use to ascend the hill.
WARNING: Continuous application of the brakes causes the
brakes to overheat, resulting in a temporary loss of braking.
If brakes do not grip well
• If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
• Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high-speed stops.
• Check brake adjustment.
• Check brake linings for excessive wear.
• Check system air pressure on vehicles equipped with air brakes.
HYDRAULIC BRAKES (IF EQUIPPED)
Full Power Brake System
This system incorporates standard braking, an anti-lock braking system
(ABS) and optional Power Park Brake into one fully-integrated hydraulic
brake system. With the Full Power Brake System, braking energy is
stored, similar to an air brake system, resulting in faster response times
and shorter stopping distances. This is accomplished using motor/pump
assemblies that pressurized the system by pumping brake fluid into
accumulators. This is similar to the air compressor of an air brake system
pressurizing the air tanks. The system includes a master cylinder that
provides the normal pedal "feel" and transfers the pedal force, via brake
fluid, to the main components of the system.
Note: The motor/pumps run momentarily with the ignition switch in the
on or run positions or the switch is in the off position and the brake
pedal is pressed.
