The parking brake assembly is designed to be completely applied before the parking brake lever completes its maximum travel.

Ensure that approximately three to six clicks with 20 kg (44 lb) of force are audible before the lever reaches its maximum pull (with the parking brake fully engaged). Adjust the parking brake, if the lever travel is outside of this range.

Look for the following conditions if the parking brake is applied and cannot be released:

    • Corroded or frozen cable(s)
    • Stuck brake shoe(s)
    • Broken or binding cable guide(s)
    • A malfunctioning release button

If the parking brake lever moves freely through its entire range without resistance and without applying the parking brake, inspect for the following causes:

    • A missing locknut from the equalizer
    • Broken parking brake cable(s)
    • Parking brake cable(s) that are disconnected at the parking brake lever(s)
