Symptom Chart: Parking Brake and Actuation

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to ENGINE CONTROLS - DIAGNOSTIC METHODS (EXCEPT DIESEL & HYBRID) for information regarding Ford-specific diagnostic practices.

Inspection and Verification

Check the operation of the parking brake system with the vehicle on a hoist and the parking brake control fully released. Check for any 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.
If the cause is not visually evident, verify the symptom and go to the Symptom Chart below.
