However, if you're experienced and comfortable working on your vehicle, here's a general overview. The exact steps and parts will vary slightly depending on the year and model of your Impala (drum brakes vs. disc brakes). Always consult a repair manual specific to your Impala's year and model. This information is for general guidance only and should not be considered a complete guide.
General Steps (May Vary):
1. Safety First:
* Park on a level surface, engage the parking brake firmly.
* Disconnect the negative battery terminal. This prevents accidental electrical shorts.
* Gather your tools and parts: These will include new brake shoes or pads, wheel cylinders (if applicable), hardware, possibly a spring compressor, wheel wrench, jack and jack stands, brake cleaner, etc. Refer to your repair manual for the exact list.
* Wear safety glasses and gloves.
2. Wheel Removal:
* Securely jack up the Impala and use jack stands to support the vehicle. Never work under a vehicle supported only by a jack.
* Remove the wheel.
3. Brake System Inspection & Preparation:
* Inspect the brake system components. Look for worn or damaged parts beyond the shoes/pads you're replacing.
* If using drum brakes: You may need a spring compressor to release the drum brake springs and remove the brake drum.
* If using disc brakes: You'll need to remove the caliper and potentially use a C-clamp to compress the piston.
4. Brake Shoe/Pad Replacement (Drum Brakes):
* Remove old brake shoes.
* Clean all components thoroughly with brake cleaner.
* Install new brake shoes, ensuring proper adjustment and alignment.
* Reinstall springs and other components.
* Reinstall the brake drum.
4. Brake Pad Replacement (Disc Brakes):
* Remove the caliper mounting bolts.
* Carefully remove the caliper and hang it out of the way.
* Remove old brake pads.
* Clean the caliper and brake caliper bracket thoroughly with brake cleaner.
* Install new brake pads.
* Reinstall the caliper and ensure the caliper slides properly.
* Compress the caliper piston (if necessary).
5. Reassembly:
* Reinstall the wheel.
* Lower the vehicle carefully.
* Reconnect the negative battery terminal.
6. Bleeding the Brakes:
* After reassembly, you MUST bleed the brakes. This removes air from the brake lines. This is a crucial step to ensure proper brake function. Follow the bleeding procedure outlined in your repair manual. Usually, you'll bleed the brakes starting with the furthest wheel from the master cylinder and working your way closer.
7. Test:
* Before driving, carefully test the brakes. Apply the brakes gently several times to ensure they are working properly.
Important Considerations:
* This is a simplified overview. Many steps require detailed knowledge and precise execution.
* Consult a repair manual specific to your Impala's year and model. This manual will provide detailed instructions, torque specifications, and diagrams.
* If you're unsure about any step, stop and seek professional help. Brake failure is extremely dangerous.
