Pinpoint Test A : The Parking Brake Does Not Apply: Notes

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation

When the parking brake control pedal is pressed the pedal should move a short distance, with more pressure needed to apply the pedal as it gets closer to the floor, until the parking brake shoes are fully applied. When the parking brake control is pressed, tension is applied to the front parking brake cable. This tension pulls on the RH rear parking brake cable, which is attached to the RH rear parking brake shoe actuator and applies the RH rear brake shoes. At the same time, the tension in the RH rear cable causes the RH rear cable conduit to attempt to straighten out. This straightening effect causes the RH rear cable conduit to pull on the LH rear parking brake cable, which is attached to the LH rear parking brake shoe actuator and applies the LH rear brake shoes.

This pinpoint test is intended to diagnose the following:

Parking brake cable(s)
Parking brake shoes and hardware
Parking brake control
