DRUM BRAKES



The rear brakes do double duty as both wheel brakes and parking brakes. Such an arrangement makes proper adjustment of the parking brakes dependent upon proper adjustment of the wheel brakes. With the wheel brakes correctly adjusted, remove the idler return spring and loosen the locknut on the convex side of the rear brake cable equalizer. Next, tighten the adjustment nut against the concave side of the equalizer until a 16 lb. strand tension is achieved in the forward brake cable. Tighten the locknut and attach the idler return spring.

DISC BRAKES



The parking brake is a conventional drum brake located in the rear wheel disc. Adjustments are similar to those for a regular drum brake.

  1. Block the front wheels. Jack the rear wheels off the ground and remove the wheels. Release the handbrake.
  2.  
  3. Rotate the disc until the adjusting screw can be seen through the hole in the disc.
  4.  
  5. Loosen the parking brake cables at the equalizer until they go slack. Insert a screwdriver and adjust with an up-and-down motion.
  6.  
  7. Tighten the adjuster until the disc cannot move, then back off six to eight notches.
  8.  
  9. Apply the parking brake to the fourth notch. Tighten the cables at the equalizer to give a light drag with the wheel mounted.
  10.  
  11. Release the parking brake and check for a no drag condition.
  12.
