* Jack and jack stands: Essential for safely lifting the car and supporting it while you work. Wheel chocks are also highly recommended for added safety.
* Lug wrench: To remove the wheels.
* Socket wrench and sockets: You'll need a variety of sizes, likely including 13mm, 15mm, and possibly others depending on the specific caliper design. A ratchet is also helpful.
* C-clamp or caliper compression tool: This is crucial for compressing the caliper piston to make room for the new, thicker brake pads. Avoid using screwdrivers or other makeshift tools; a dedicated tool prevents damage.
* Wrench or socket for caliper mounting bolt(s): The size will vary.
* Pliers: May be needed to help with removing and installing the retaining clips or pins holding the brake pads in place. Needle-nose pliers might be useful for smaller components.
* Brake cleaner: Essential for cleaning the caliper and brake components before installing the new pads.
* New rear brake pads: Obviously! Make sure you get the correct ones for your 2002 Impala.
* Penetrating oil (like PB Blaster): Helps loosen any rusted or stuck bolts. Apply this beforehand if needed.
* Gloves: To keep your hands clean.
* Safety glasses: To protect your eyes from flying debris.
Optional but helpful:
* Torque wrench: To tighten bolts to the manufacturer's specified torque. This ensures proper function and prevents damage.
* Wheel chocks: As mentioned above, these are crucial for safety.
Remember to consult your owner's manual or a repair manual specific to your 2002 Impala for detailed instructions and torque specifications. If you're uncomfortable working on your brakes, it's always best to take it to a qualified mechanic. Brake failure can be dangerous.
