DRUM TYPE BRAKES
- Raise and support the rear of the vehicle on jackstands.
- Remove the rubber cover from the backing plate.
- Insert a brake adjusting tool through the hole in the brake backing plate. Turn the toothed adjusting nut to spread the brake shoes, making contact with the brake drum.
When adjusting the brake shoes, turn the wheel until considerable drag is felt.
- When considerable drag is felt, back off the adjusting nut a few notches, so that the correct clearance is maintained between the brake drum and the brake shoes. Make sure that the wheel rotates freely.
See Figures 1 and 2
Before adjusting the pedal, make sure that the brakes are correctly adjusted. Adjust the pedal free play by means of the adjustable pushrod or by replacing shims between the master cylinder and the brake booster or firewall. Free play should be approximately 15mm on all models through 1984. On all models from 1985-92 the pedal free play should be 13mm. Refer to the illustration.
Adjust the pedal height by means of the adjustable pedal arm stop pad in the driver's compartment on models through 1984. On later models, adjust the brake booster input rod by loosening the lock-nut and turning the rod.
The pedal height (floorboard-to-pedal pad) should be approximately 178mm for 1982-83 200SX model.
On the 1984-86 1 / 2 200SX, it should be 189-199mm on cars with a (manual transmission) and 191-201mm on cars with (automatic transmission).
On the 1986 1 / 2 88 200SX, it should be 185-195mm on cars with a (manual transmission) and 187-197mm on cars with (automatic transmission).
The brake pedal free height for the 1989-92 240SX model is 177-187mm for (manual transmission) and 186-196mm for (automatic transmission).
The brake pedal free height for the Stanza models is 159-169mm for (manual transaxle) and 169-179mm for (automatic transaxle). The early Stanza models pedal height (floorboard to pedal pad) is 152mm. Refer to the illustration.
