From PT Do-It-Yourself.net:

The parking brake is self -adjusting and only applies to the rear brakes. The parking brake lever automatic-adjusting feature continuously applies minimal tension to the parking brake cables to keep them in adjustment at all times. Therefore, the parking brake cable system does not require adjustment. Proper parking brake system adjustment is obtained by proper drum brake or drum-in-hat brake shoe adjustment. This section of the service manual is extensive and contains numerous illustrations and instructions, therefore we're not able to provide it in its entirety. We recommend that you borrow or purchase a service manual prior to attempting any adjustment to the brake system.
