Fig. 2 Adjusting brake shoes to brake drum inside diameter:

300ZX models, 1985-88 200SX models and some Maxima models are equipped with four wheel disc brakes, therefore, no adjustments are necessary on these models.
Models equipped with drum brakes have self-adjusting shoe mechanisms that ensure correct lining-to-drum clearance through actuation of the parking brake. Although the brakes are self-adjusting, an initial adjustment is necessary after the brake shoes have been replaced.
To perform adjustment, measure brake drum inside diameter using a suitable brake drum-to-shoe gauge, Fig. 1. Adjust brake shoes to dimension obtained on outside of gauge, Fig. 2.
