The brake shoes in your vehicle work like the brake pads do in a disc brake application, by applying friction until you come to a stop. But instead of two brake pads pressing against either side of the caliper, your drum brake shoes are curved brackets that push outward against the inside of your brake drum.
This action is created from your brake master cylinder pushing hydraulic fluid into the wheel cylinder, which in turn pushes the arms of your brake shoes. Your brake shoes are attached by way of a lower tension spring that brings the brake shoes back into place after you let go of the brake pedal.
On the other side of your brake shoe, is the brake lining or the friction material that stops you. Usually brake shoes have the linings bonded or riveted to ensure proper engagement with the brake drum. When you are installing your new brake shoes, always make sure to line up the largest shoe in front.
This is because as you apply the brakes, your vehicle shifts weight and has a tendency to dip forward. Because of this natural weight transfer when coming to a stop, you want the largest brake shoe with the most surface area to bear the load.
Unfortunately, as with any friction type material or component of your automobile, brake linings and brake shoes eventually wear. Improper installation of your brake shoes can cause stress cracking or glazing of your shoe or your brake drum.

This arm will automatically turn the star wheel in the adjuster arm, but you will still need to set the tension in the adjuster arm manually before the brake drum will fit back over the entire assembly.
Using the pilot hole on the back of the mounting plate turn the star wheel until the arm has taken up any slack in the brake shoes.
With the caliper removed, gently and carefully place your caliper on top of your rotor as shown.
Make sure it does not fall or cause any stress to the rubber brake line.
Remove the old rotor and set to the side, open your Centric box and remove your new rotors. Slide on the new brake rotors and use the impact screwdriver to reinstall the set screws.
After you have completed this step, you should feel your brake pedal compress slightly, which should make your brake pedal sink downward.
Now allow the engine to build vacuum while idling for a bit, and then turn the vehicle off.
With the vehicle turned off, depress the brake pedal slowly and firmly and repeat this process.
With each and every pump of your brake pedal, you should feel your brakes stopping higher and higher at each interval.
