6. Rear drum brake adjustment

1. Rear drum brake lining gap adjustment (Except after overhaul)

All brakes are automatic adjustment type. The lining gap is automatically adjusted by repeatedly depressing the brake pedal.

1) Repeatedly depress and release the brake pedal until the click of the auto adjuster is not heard.

2) When the clicking sound can no longer be heard, depress the brake pedal 10 times to make sure that there is no stroke variation.

2. Rear drum brake lining gap adjustment (After overhaul, bench seat specifications)

1) Release the parking brake lever by moving it to the position where it is completely released.

2) Loosen the adjust nut using a wrench.

3) Repeatedly depress and release the brake pedal until the click of the auto adjuster is not heard.

Note

  • If the clearance between the brake drum and the lining is adjusted to 0.5 mm {0.020 in}, the number of times of depressing the brake pedal can be reduced.

4) When the clicking sound can no longer be heard, depress the brake pedal 10 times to make sure that there is no stroke variation.

5) Remove the cover from the back plate.

6) Measure the gap between the brake drum and brake shoe.

Standard: 0.25 to 0.40 mm { 0.0098 to 0.0157 in } Lining clearance

Note

  • If it is outside the standard range, inspect the adjuster.

7) Turn the adjust nut so that the parking brake lever is pulled up 6 to 9 notches when the lever is pulled up with the force of 294 N {30 kg/66 lb}.

Caution

  • Make sure the brake does not drag.
