Test A: The Parking Brake Does Not Apply

Pinpoint Test A: The Parking Brake Does Not Apply

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 pedal is pressed, tension is applied to the front parking brake cable. This tension pulls 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. At the same time, the tension in the LH rear cable causes the LH rear cable conduit to attempt to straighten out. This straightening effect causes the LH rear cable conduit to pull 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.

This pinpoint test is intended to diagnose the following:
^ Rear parking brake cables and conduits
^ Front parking brake cable and conduit
^ Parking brake shoes and hardware
^ Parking brake control
