Pinpoint Test B: The Parking Brake Will Not Release Using the Release Handle

Normal Operation
When the parking brake release handle is pulled, the ratchet mechanism and return spring in the parking brake control release the tension on the parking brake cables and conduits. The LH rear parking brake cable conduit and the springs on both rear cables provide the force necessary to return the parking brake shoes to their released position.

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