Ford 2007 F-650 Owner's Manual page 102

Push the palm release lever on the
parking brake handle and push
down as far as possible to release
the brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
If the parking brake is fully
released but the parking
brake warning lamp remains
illuminated, the brakes may not be
working properly. See your dealer
or a qualified service technician.
The parking brake is not
recommended to stop a moving
vehicle. However, if the normal
brakes fail, the parking brake can be
used to stop your vehicle in an
emergency. Since the parking brake only applies retardation to the rear
wheels, the vehicle's stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
POWER PARK (AIR-OPERATED PARKING BRAKE) OPTION (IF
EQUIPPED)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, air-released driveline parking brake. It is controlled by a
yellow, dash-mounted parking brake knob.
Applying the parking brake
To apply the parking brake, pull the yellow, dash-mounted parking brake
knob. A red light on the dash panel should illuminate indicating that the
parking brake has been successfully set.
Note: If the park brake indicator light blinks and a warning chime
sounds when the control knob is pulled, the parking brake is not
functioning properly; seek immediate service from your dealer. Refer to
the Parking Brake Warning System section.
