Thanks for the info. The problem I am having is specifically with the parking brake cable. There is too much tension on the cable an spring to allow me to hook it back on the lever of the new shoe. I read somewhere that a person needs to find the adjustment nut under the center console and relieve the tension that way. If this is not correct, then please let me know, Otherwise I am diving in to the center console to gain access to the adjustment. I've never encountered anything like this in all the brake jobs I have performed in the past, but it seems like the only way.
Expert:  John replied 4 years ago.

Ok,here is the information you requested.It is inside the console.

 

Parking Brake Adjustment (Drum Brake)

 

Important: The park brake cable adjusting nut is a nylon lock type. Use ONLY HAND TOOLS whenever tightening or loosening the adjusting nut.


    Object Number: 891424  Size: SH

  1. Apply and fully release the park brake several times. Verify that the park brake lever releases completely.
  2. Turn ON the ignition. Verify the red BRAKE warning lamp is not illuminated.
  3. If the red BRAKE warning lamp is illuminated, verify the following:
    The park brake lever is in the fully released position and against the stop.
    There is no slack in the park brake cables.
  4. If the red BRAKE warning lamp remained illuminated and there were no other visible causes,
  5. Turn OFF the ignition.
  6. Release the park brake lever boot from the floor console by applying light pressure inward on the sides of the boot retainer, and pull the boot back.
  7. With the park brake lever in the released position, loosen the adjusting nut (1) enough to completely relieve tension on the front cable.
  8. Raise and support the vehicle. Raise the vehicle just enough to allow rear tire and wheel assembly removal and rear drum adjustment. Remove the rear tire and wheel assemblies.
