- Turn the adjuster on each
of the parking brake self adjusters until both sets of parking brake shoes
  just contact the parking brake drum, with no significant drag.
 
- Tighten the adjuster nut on the parking brake lever shaft until
braking effort occurs while ensuring the wheels turn   freely.
 
- Perform the following inspection:
 
| 3.1.  | Ensure the wheels still turn with the parking brake lever set
on the 4th notch. | 
 
| 3.2.  | Ensure the wheels are tight with the parking brake lever set on
the 7th notch. | 
 
| 3.3.  | Additionally, ensure the braking effort is equal at both wheels. | 
 
- The adjustment procedure is complete when the above inspections
are correct.
