Essential Tools:
* Jack and jack stands: Crucial for safely lifting the car. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheel nuts.
* Sockets and ratchet: You'll need sockets that fit your lug nuts (likely 16mm or 17mm) and a ratchet to turn them. A breaker bar might be helpful if the lug nuts are tight.
* C-clamp or caliper compression tool: To compress the caliper piston to allow the new rotor to fit. A C-clamp works, but a purpose-built caliper compression tool is safer and easier.
* Hammer (rubber mallet preferred): May be needed to gently tap the rotor to remove or install it.
* Wrench to remove caliper mounting bolts: The size will depend on your specific model; consult your repair manual or a parts diagram.
* Torque wrench: Essential for properly tightening the lug nuts and caliper mounting bolts to the manufacturer's specified torque. This prevents damage and ensures safety.
* Wire brush or brake cleaner: To clean the mating surfaces of the hub and rotor.
* Gloves: To keep your hands clean.
* Safety glasses: To protect your eyes from flying debris.
Highly Recommended Tools:
* Repair manual: A specific repair manual for your 2004 Chevy Impala will give you detailed instructions and torque specifications. This is invaluable.
* Penetrating oil (like PB Blaster): To loosen any stubborn bolts. Apply this in advance.
Potentially Needed Tools:
* Rotor removal tool: Some rotors require a special tool for removal. While often unnecessary, check to see if your Impala requires this before starting the job.
Important Note: Always consult a repair manual specific to your vehicle year and model before beginning any repair work. The exact bolt sizes and procedures can vary slightly between models and years. If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Brake work is crucial for safety, and improper repair can lead to serious consequences.
