1. Block the front wheels to prevent movement.
2. Fully release the hand brake.
3. Back off the brake adjusters slightly.
4. WITH THE REAR WHEELS STILL ON THE GROUND, remove the cotter pin from the castle nut on the rear wheel shaft. Mark both the nut and the end of the axle where the cotter pin went thru so you can torque the nut to the same place when replacing it. Break the rear axle nut loose with a 36mm (1-7/16" socket) on a 3/4-inch drive breaker bar and "cheater" -- a length of pipe about four feet long to slip over the breaker bar to give more torque. The nuts on both sides are normal treads - lefty-loosey, righty tighty. Remove the castle nut, then raise the car.
WARNING -- Loosen the two castle nuts (one on each side) while the car is on the ground. The castle nut should have at least 217 ft-lbs of torque on it -- the leverage needed to remove it is enough to topple a car off the jack stands.
Note: If your car is equipped with spinners (like ours is), the castle nuts will not be accessible with the wheels on the car. After removing the rear wheels, we had success with lowering the brake drums down onto large blocks of wood and firmly applying the parking brake. This plus the weight of the car on the wooden block held the brake drums in place while we removed and later replaced the castle nuts.
5. Loosen the wheel lug bolts/nuts and raise the rear of the car and place it securely on jack stands.
6. Remove the wheel lug bolts/nuts and remove the rear wheels.
7. Back off the brake adjusting stars if needed, then remove the brake drum from the splines in the rear wheel shaft. You now have the inner workings of the rear brakes exposed.
8. Remove the rubber boot from the brake handle (inside the car).
9. Use two 10mm wrenches to loosen and remove the adjusting nuts on the top of the cable (two on each side). Hold the cable from turning with a screwdriver in the slot.
10. Remove the compensating lever.
11. Return to the rear of the car and disconnect the bolt that attaches the hand brake cable to the backing plate (on the rear of the backing plate).
Note: If you're replacing both cables, do one cable at a time so you'll have the other cable as a reassembly guide.
12. Pull the rear end of the cable and cable guide and cable through the backing plate and pull the rest of the cable out of the guide tube.
13. Clean the cable and guide tube.
Note: On cars manufactured since August 1, 1966, the rear wheel track is wider. These models have longer hand brake cables. Compare the lengths of the new cable and the old cable to make sure you have the right replacement cable.
14. Lubricate the whole cable with any multi-purpose grease. You can grease your fingers and slowly run the cable through your fingers - a bit messy but you need a nice coating of grease on the full length of the cable.
15. Thread the front end of the cable through the guide tube and the rear end of the cable through the brake backing plate.
16. Install the brake shoes and attach the hand brake cable to the lever on the rear shoe.
17. Loosely install the cable adjusting nut and locknut at the hand brake lever.
18. If you are replacing both cables, repeat the foregoing for the other cable.
19. Reinstall the brake drum.
Note: Since there are no bearing in the rear brake drums, installation is straightforward. Simply slip the new drum onto the splines in the rear wheel shaft. The only problem you may encounter is getting the new drum over the new shoes. Back off the brake adjusting stars completely to provide clearance.
20. Reinstall the wheels.
22. Adjust the brakes according to the Brake Adjustment procedure.
23. Adjust the hand brake cable in accordance with the procedure above.
24. Carefully lower the rear of the car to the ground.
