Here's a general outline. This is NOT a substitute for a repair manual specific to your 1997 Chevy Lumina. Consult a repair manual for detailed instructions, diagrams, torque specifications, and potential variations specific to your vehicle's configuration (e.g., drum size, parking brake mechanism).
Tools You'll Need:
* Jack and jack stands
* Wheel chocks
* Lug wrench
* Socket set (various sizes, including metric)
* Ratchet and extensions
* Pliers (various types, including slip-joint and needle-nose)
* Screwdrivers (Phillips and flathead)
* C-clamp (or brake shoe spreader)
* Wire brush
* Brake cleaner
* Grease
* New rear brake shoes (including springs, clips, and hardware – get a kit)
* New brake drums (optional, but recommended if drums are scored or rusty)
* Torque wrench
Steps (General Outline – Consult your repair manual for specifics):
1. Safety First: Park on a level surface, 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 wheel.
3. Remove the Drum: Often, the brake drum simply slides off. If it's stuck, gently tap around the perimeter with a rubber mallet. If it's still stuck, you may need to use a drum puller (available at auto parts stores).
4. Inspect the Components: Carefully inspect the brake shoes, springs, return springs, wheel cylinders, and the drum itself for wear and tear. Replace any damaged or worn components. Note the position and orientation of all parts before removing them.
5. Remove the Old Brake Shoes: This usually involves removing various springs and pins connecting the shoes to the backing plate. Be careful not to lose any small parts.
6. Clean Everything: Thoroughly clean the backing plate, brake drum, and all brake components with brake cleaner. Use a wire brush to remove any rust or debris.
7. Install the New Brake Shoes: Install the new brake shoes, springs, and other components in the reverse order of removal. Ensure everything is properly seated and aligned. The repair manual will show the correct placement of all parts. Pay close attention to the self-adjusting mechanism (if present).
8. Adjust the Brake Shoes: You will likely need to use a C-clamp or brake shoe spreader to initially adjust the shoes to fit the drum. This ensures even contact between the shoes and drum.
9. Install the Drum: Carefully slide the brake drum back onto the backing plate. It should slide on easily. If it's tight, there might be a problem with the shoe adjustment.
10. Reinstall the Wheel: Reinstall the wheel and tighten the lug nuts to the manufacturer's specified torque (check your repair manual).
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Test the Brakes: After reinstalling both rear wheels, pump the brake pedal several times and test the parking brake. Have someone assist you by watching the wheels to make sure they turn freely. If you feel spongy brakes or the parking brake is ineffective, you'll need to investigate further. You may need to bleed the brakes.
13. Professional Brake Service: If you are uncomfortable performing this task yourself, or if you are unsure about any step, take your vehicle to a qualified mechanic for brake service. Brake failure can have serious consequences.
Important Notes:
* Repair Manual: A repair manual specific to your 1997 Chevy Lumina is crucial for this job. It will provide detailed instructions, diagrams, torque specifications, and other essential information.
* Safety: Brake work is dangerous. If you aren't comfortable working on brakes, take your car to a professional. Incorrectly adjusted brakes can be dangerous and lead to accidents.
* Bleeding the Brakes: Depending on your work, you may need to bleed the brakes to remove air bubbles from the brake lines. This requires a helper.
This is a general guide. Consult your vehicle's repair manual for precise instructions and safety precautions. Remember, working on your brakes improperly can lead to serious injury or death. If you are unsure about any step, consult a professional mechanic.
