Need a spring diagram for 76 chevy 3/4 ton drum brakes

there is a lever attached to a shoe that activates on the notched wheel of the adjuster bar. The same notched wheel that is used to adjust the brakes through the back or drum. When the shoes moves from the braking action the spring pulls the lever and turns the notched wheel. this is repeated every time the brakes are applied until there is a position where the lever cannot get into the next notch.Any drum brake set up with automatic brake adjustment will look the same so any chev manual will show how to put it together.

CAUTION
Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid. NOTE: A brake spring removal tool and a brake adjusting gauge are required for this procedure.

1. Raise and support the vehicle safely with jackstands.
2. If the brakes have never been serviced before, the drums will be held on the wheel studs with spring nuts. Remove the spring nuts and discard.
3. Turn the adjustment starwheel so that the brake shoes are retracted from the brake drum and remove the brake drum.
4. Install wheel cylinder clamps to retain the wheel cylinder pistons in place and prevent leakage of brake fluid while replacing the shoes.
5. Remove the U-clip and washer securing the adjuster cable to the parking brake lever.
6. Remove the adjuster cable, cable guide, adjuster lever and adjuster springs. Remove the return springs with a brake spring remover tool.
7. Remove the hold-down retainers and springs, then remove the brake shoes. To install:

there should be several springs. first there are (2) real short springs that hold the shoes to the dust cover/back plate. they go in the center of each shoe. then there is a short spring that goes at the bottom where the adjuster is located. there should be a hole in each shoe. finally there is a long spring that goes at the top where your brake cylinder is and this is what gets attched last after your emergancy brake levers are placed between the shoes .

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 .
