Tools you'll likely need:
* Jack and jack stands: Absolutely essential for safety. Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the car from rolling.
* Socket set and wrenches: Various sizes will be needed, consult your repair manual.
* C-clamp or brake spring pliers: To compress the brake springs. These are specialized tools and are crucial.
* Screwdrivers (Phillips and flathead): Possibly needed for various fasteners.
* Brake cleaner: To clean parts.
* Grease: For lubrication of pins and other parts.
* New rear brake shoes: Get the correct parts for your specific model Malibu. Often, you'll need a kit that includes the shoes, springs, and hardware.
* Repair manual: A Haynes or Chilton manual for your specific year and model is highly recommended. It will have detailed diagrams and instructions.
General Steps (Consult your repair manual for precise details):
1. Safety First: Engage the parking brake, chock the front wheels, and raise the rear of the vehicle securely using the jack and jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Drum: The rear brake drum is usually held on by the wheel studs. It may be stuck due to rust; you might need to tap it gently with a hammer and a block of wood to loosen it.
4. Inspect the Components: Once the drum is off, carefully examine all the components: brake shoes, springs, wheel cylinder, and the drum itself. Take pictures before disassembling anything to help with reassembly.
5. Remove the Old Brake Shoes: This is where the C-clamp or brake spring pliers are essential. The springs hold the shoes in place; you'll need to carefully compress them to release the shoes. The order in which you release springs varies depending on the design, so refer to your repair manual. Take note of how the springs and other hardware are arranged.
6. Clean and Inspect: Clean all parts thoroughly using brake cleaner. Inspect the wheel cylinder for leaks. If it's leaking, you'll need to replace it. Inspect the brake drum for scoring or excessive wear.
7. Install the New Brake Shoes: Install the new brake shoes, making sure to position them correctly according to your repair manual or pictures you took.
8. Reassemble the Springs: Carefully reattach the springs using the C-clamp or pliers. Make sure they are properly seated. This step is crucial for correct brake function and can be tricky. Again, your repair manual is invaluable here.
9. Install the Brake Drum: Carefully place the brake drum back on, making sure it's properly seated.
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts.
11. Lower the Vehicle: Carefully lower the vehicle to the ground.
12. Test and Adjust: Tighten the lug nuts securely. Pump the brake pedal several times to ensure the brakes are working correctly. You may need to adjust the brake shoes for proper clearance. Your repair manual should detail how to do this.
Important Considerations:
* Wheel Cylinder: If the wheel cylinder is leaking, it must be replaced. Leaking wheel cylinders are a common cause of rear brake failure.
* Brake Drum: If the brake drum is scored or worn excessively, it should be replaced or turned on a lathe.
* Safety: Brake work is potentially dangerous. If you are unsure about any step, consult a professional mechanic. Improperly adjusted brakes can lead to accidents.
This is a simplified overview. Always refer to a repair manual specific to your 2002 Chevy Malibu for detailed instructions and diagrams. Improperly following these instructions can lead to brake failure, resulting in serious injury or death. If you're unsure, seek professional help.
