2.Remove rear brake drums from hub and bearing assemblies after loosening the two brake drum screws.

3.Be sure that the parking brake pedal is in the release(most upward) position.

4.Completely loosen square nut of the rear parking brake cable. Then create slack in the rear parking brake cables.

5.Remove adjuster spring from adjust lever and brake shoe.

6.Remove adjust lever and turn the adjusting wheel of adjuster assembly to the direction of the arrow as shown.

7.Remove the strut spring and the lower retracting spring from the brake shoe.

8.Remove the upper return spring from the brake shoe.

9.Remove brake back plate hold down spring and pin from the leading brake shoe assembly.

10.Remove the leading brake shoe. Then remove the adjuster assembly, strut and anchor spring from the trailing brake shoe.

11.Remove the trailing brake shoe from the brake back plate after removing hold down spring and pin.

12.Remove the trailing brake shoe from the rear parking cable.

13.Remove parking pivot lever from the leading brake shoe.

Replacement
1.Lubricate the eight shoe contact areas on the back plate and anchor.

9.Install the adjuster spring on the adjust lever and leading brake shoe assembly.

10.Install the leading brake shoe hold down spring and pin on the brake shoe.

11.Adjust brake shoes assemblies so as not to interfere with brake drum installation.

12.Install the rear brake drums on the hubs.

13.Check and adjust whether the pedal stroke in the specification.(Refer to section BR Gr./On-vehicle service/Pedal stroke of parking brake)

14.Install wheel and tire.

15.Push the parking brake pedal to the floor once and release pedal. This will automatically remove the slack from and correctly adjust the parking brake cables.

16.Test the vehiche on the road. The adjust will continue the brake adjustment during the road test of vehicle.

Inspection
1.Inspect the disassembled parts for wear, rust or damage.

2.Measure the thickness of brake shoe lining.
Standard : 0.17 in (4.5 mm)
Minimum : 0.04 in (1 mm)

3.If the shoe lining is less than minimum or shows signs of uneven wear, replace new one.

4.Measure the inside diameter of the brake drum.
Standard : 10 in (254 mm)
Maximum : 10.07 in (256 mm)

5.If the inside diameter of the brake drum is more than maximum or shows signs of uneven wear, replace new one.

6.Inspect the lining and drum for proper contact. If the contact condition is improper, repair it with a grinder or replace the brake shoe assembly.

Fig. Exploded view of the rear drum brake assembly - LINK
The rear brakes do not require manual adjustment. Adjust the shoes by sharply applying the brake pedal several times while driving the vehicle alternately forwards and backwards. Check the brake operation by making several stops while driving forward. The self-adjusting mechanism will sufficiently adjust the rear brake shoes without any manual tightening at the brake shoe adjuster. If the rear brake shoes are manually adjusted, the additional action of the brake shoe adjuster can cause the brakes to become over-tightened and result in binding or overheated rear brakes.

Hope this helps.

The rear drum brakes:

• Have internal shoes that expand against the brake drum (1126).
• Are a single-anchor type.
• Are actuated by one rear wheel cylinder (2262).
• Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
• Adjust rear brake shoes and linings (2200) automatically.
• Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.

When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .
