Hints On Driving With Anti-Lock Brakes; Parking Brake - Ford Super Duty Owner's Manual

224
If the anti-lock brake system is disabled, normal braking is still
effective. If the brake warning lamp illuminates with the parking
brake released, have your brake system serviced immediately.

HINTS ON DRIVING WITH ANTI-LOCK BRAKES

When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not eliminate the dangers inherent
when:
• you drive too closely to the vehicle in front of you.
• your vehicle is hydroplaning.
• you take corners too fast.
• the road surface is poor.

PARKING BRAKE

WARNING: Always set the parking brake fully and make sure that
the transmission selector lever is securely latched in position P.
To set the parking brake, press the parking brake pedal down until the
pedal stops.
The BRAKE warning lamp in the instrument cluster will illuminate and
remains illuminated until the parking brake is released.
To release, pull the brake release lever located at the lower left side of
the instrument panel.
If you are parking your vehicle on a grade or with a trailer, press and
hold the brake pedal down, then set the parking brake. There may be a
little vehicle movement as the parking brake sets to hold the vehicle's
weight. This is normal and should be no reason for concern. If needed,
press and hold the service brake pedal down, then try reapplying the
parking brake. Chock the wheels if required. If the parking brake cannot
hold the weight of the vehicle, the parking brake may need to be
serviced or the vehicle may be overloaded.
