Symptom Chart: Parking Brake and Actuation
Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).
Check
the operation of the parking brake system with the vehicle on a hoist
and the parking brake control fully released. Check for damaged cables
and install new components as necessary.
The
first indication that something may be wrong in the parking brake
system is a change in the feeling through the parking brake control. The
parking brake not holding on an incline or dragging after being
released are also indicators of system concerns.

Verify the customer concern.
-
Visually inspect for obvious signs of mechanical damage.
-
If an obvious cause for an observed or reported concern is found, correct the cause.

-
Front parking brake cable
-
Rear parking brake cables and/or equalizer
-
Rear brake shoes and/or hardware
Is any damage found or are any components disconnected?
Yes |
CONNECT the component(s) or INSTALL new parking brake component(s) as necessary.
