The Park Brake System is a mechanical system. The lever is connected to the front cable. The front cable runs from the lever to the equalizer. The equalizer connects the front cable to the two rear cables. One rear cable runs from the equalizer to each rear wheel. The rear cable engages the park brake mechanism. Applying the park brake prevents the rear wheels from turning.

Park Brake Lever

Pull the lever all the way up in order to apply the park brake.

Complete the following steps in order to release the park brake:

  1. Pull the lever up slightly.
  2. Push in the release button.
  3. Lower the lever.

Park Brake Cables

The twisted strand park brake cables are covered by a plastic material that allows the cables to slide freely.

The front cable is secured to the lever by two nuts. The lower nut controls the adjustment of the park brake. The upper nut locks the lower nut in place.

The front cable is connected to the two rear cables by an equalizer. The equalizer ensures that the braking tension is applied to both brakes at the same time, and with the same amount of pressure.

BRAKE Indicator

Applying the park brake illuminates the BRAKE indicator on the instrument cluster. For Information regarding the BRAKE indicator, refer to Brake Warning System Description and Operation .

Park Brake Switch

The park brake switch mounts to the parking brake lever. The switch is open when the park brake releases. When the park brake lever is pulled up, the switch closes, illuminating the BRAKE indicator.

Daytime Running Lamps (DRL)

If the engine is started with the park brake engaged, the daytime running lamps (DRL) will not illuminate.

Release the park brake in order to illuminate the DRL.

If the engine is started with the park brake released, the DRL will illuminate. Applying the park brake after starting the engine will not disable the DRL.

For more information regarding DRL, refer to Exterior Lighting Systems Description and Operation .
