INITIAL ADJUSTMENT

Use this procedure when a new tension limiter is installed.

1. Apply the parking brake pedal to the fully engaged position.
2. Raise and safely support the vehicle, as necessary. Hold the threaded rod end of the right brake cable to keep it from spinning and thread the equalizer nut 2 ¹⁄₂ inches (63.5mm) up the rod.
3. Check to make sure the cinch strap has slipped and there are less than 1 ³⁄₈ inches (35mm) remaining.
4. Release the parking brake and check for proper operation.

FIELD ADJUSTMENT

Use this procedure to correct a slack system if a new tension limiter is not installed.

1. Apply the parking brake pedal to the fully engaged position.
2. Raise and safely support the vehicle, as necessary. Grip the threaded rod to keep it from spinning and tighten the equalizer nut 6 full turns past its original position on the threaded rod.
3. Attach a suitable cable tension gauge in front of the equalizer assembly on the front cable and measure the cable tension. The cable tension should be 400–600 lbs. (181.5–272 kg) with the parking brake pedal in the last detent position. If tension is low, repeat Steps 2 and 3.
4. Release parking brake and check for rear wheel drag. There should be no brake drag.
