Normal Operation
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
When the parking brake control is fully applied and the pedal is pressed a second time, the ratchet mechanism and return spring in the parking brake control cause the tension on the parking brake cables to release. The springs on both rear parking brake cables and the spring on the equalizer provide the force necessary to return the system to the released position.
This pinpoint test is intended to diagnose the following:
- Parking brake cable(s)
- Parking brake control
- Parking brake shoe actuators
- Parking brake shoes and hardware
