What is included in a drum brake hardware kit?

Why does my rear suspension make a clicking noise?
Wheel bearings can also emit a clicking noise, but so can rear drum brakes and failed drum brake shoes. If you have drums and hear clicking, check those out before you assume a bad wheel bearing.
Why are my drum brakes not working properly?
Carefully examine the brake mechanisms on both wheels. There are two return springs connecting the front and rear brake shoes, and if either of these is broken or weakened, the shoes will not retract properly and they will drag on the drum. Hold the adjuster lever off of the adjuster wheel and turn the wheel back and forth.
What should I do if I hear a thumping noise on my brakes?
Do this three to five times, while keeping a steady speed; the noise should disappear, or at least be 90% gone. Then drive the car at normal speeds and use the brakes the way you normally would. If the noise has not changed, you may have a different thumping noise than what I have described here in this article.
What causes rear drum brakes to engage too soon?
If the parking brake system is not de-adjusted properly before the brake shoes are adjusted it will cause the rear brakes to engage too soon. This is especially true of vehicles equipped with duo-servo rear drum brakes (see Figure 61.1).
Where are drum brakes used on a car?
Drum brakes are common on older automobiles, and on lower-cost vehicles they are still frequently used on the rear wheels. While not as effective or reliable as modern disc brakes, drum brakes have the advantage of being less expensive and lighter, and when used in the rear position they do not seriously impair the braking function.
Why does my car make a thumping noise when I hit the brakes?
If the groove is interrupted, the shoes snap back, hitting the backing plate. This phenomenon happens very quickly, causing a thumping noise that will drive you crazy and wondering if your car is falling apart or even safe to drive. There are several ways to fix this noise. One is to replace the rear drums.
Can a out of round drum cause rear wheel lockup?
Brake drum condition should be factored in when determining the cause of rear wheel lockup. An out of round brake drum or drums that vary in diameter too much from side to side could cause a one wheel lockup condition (Figure 61.8). Measuring drum runout or out of roundness is not easy in the field.
