Essential Tools:
* Jack and Jack Stands: Absolutely crucial 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.
* Sockets and Wrenches (Metric): You'll need a range of sizes, likely including 13mm, 14mm, 15mm, and possibly others depending on the caliper bolts and other fasteners. A socket set with a ratchet is highly recommended.
* C-clamp or Brake Caliper Compression Tool: This is essential for compressing the brake caliper piston to make room for the new brake pads. A C-clamp can work, but a dedicated tool is safer and easier to use.
* Pliers: Needle-nose pliers might be helpful for reaching small fasteners or clips.
* Torque Wrench: Crucial for tightening bolts to the manufacturer's specified torque. Improper torque can lead to brake failure. Consult your owner's manual for torque specifications.
* Brake Cleaner: To clean brake parts before installation.
* Wire Brush: To clean caliper slides and other parts.
* Gloves: To protect your hands from grease and dirt.
* Safety Glasses: To protect your eyes from flying debris.
Optional but Helpful Tools:
* Impact Wrench (optional): Can speed up the process of removing lug nuts.
* Wrench Set: A combination wrench set complements your socket set, offering a different grip if needed.
* Penetrating Oil (like PB Blaster): Helps loosen stubborn bolts.
* Large Flathead Screwdriver (potentially): Some brake systems may use a retaining clip that requires a flathead.
Important Considerations:
* Consult your owner's manual: Your owner's manual will provide specific torque specifications and might offer helpful diagrams or instructions.
* Safety First: Working on brakes is serious business. If you're not comfortable working on cars, take your Grand Prix to a qualified mechanic. Improperly installed brakes can lead to serious injury or death.
* Brake fluid: You may need to bleed the brakes if you completely remove the calipers or replace a brake line. This requires a brake bleeding kit and a helper.
This list provides a comprehensive overview. The specific tools you'll need might vary depending on the exact condition of your brake system and any unique features of your 2003 Pontiac Grand Prix. Remember to always prioritize safety!
