However, if you're determined to proceed, here's a general outline. This is not a comprehensive guide, and specific steps may vary slightly depending on the exact model and trim level of your Bonneville. Always consult a repair manual specific to your vehicle for detailed instructions and diagrams.
Tools You'll Need (at minimum):
* 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.
* Socket wrench set: With metric sockets (most likely).
* Wrench set: Various sizes for caliper bolts, etc.
* C-clamp or brake caliper compressor tool: To compress the caliper piston.
* Brake cleaner: To clean brake parts.
* New brake pads and rotors (if necessary): Make sure to get the correct parts for your Bonneville.
* Torque wrench: Essential for tightening bolts to the correct specification (found in your repair manual).
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
* Penetrating oil (like PB Blaster): May help loosen rusted bolts.
General Steps (Front Brakes - Rear brakes are similar but often simpler):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks.
2. Raise and Secure: Jack up the vehicle and securely place it on jack stands.
3. Remove Wheel: Remove the lug nuts and carefully take off the wheel.
4. Remove Caliper: Locate the caliper mounting bolts and carefully remove them. Sometimes, you may need to use penetrating oil first. The caliper may be heavy; support it as you remove the bolts.
5. Compress Caliper Piston: Use a C-clamp or caliper compressor to push the piston back into the caliper. This creates space for the new, thicker pads. Be careful not to damage the piston.
6. Remove Old Pads: Remove the old brake pads. Take note of their orientation; some pads have wear sensors or shims.
7. Inspect Rotor: Inspect the brake rotor for wear, scoring, or excessive rust. If necessary, replace the rotor.
8. Install New Pads: Install the new brake pads, ensuring they are correctly seated.
9. Reinstall Caliper: Reinstall the caliper, making sure it's properly aligned.
10. Tighten Bolts: Tighten the caliper mounting bolts to the manufacturer's specified torque.
11. Reinstall Wheel: Reinstall the wheel and tighten the lug nuts.
12. Lower Vehicle: Carefully lower the vehicle from the jack stands.
13. Repeat: Repeat steps 1-12 for the other front wheel.
14. Bleed Brakes (IMPORTANT): After installing new brake pads, you *must* bleed the brakes to remove any air trapped in the brake lines. This is a crucial safety step that requires a helper and a bleeding kit. Improper bleeding can lead to spongy brakes. Refer to your repair manual for detailed bleeding instructions.
15. Test Brakes: Before driving, carefully test your brakes several times.
Important Considerations:
* Rear Brakes: The process for the rear brakes is similar, but might involve different types of calipers (e.g., drum brakes or self-adjusting calipers).
* Repair Manual: A Haynes or Chilton repair manual specific to your 2002 Pontiac Bonneville is invaluable. It provides detailed diagrams, torque specifications, and troubleshooting advice.
* Parts: Get the correct parts from a reputable auto parts store. Make sure they're specifically for your vehicle's year, make, and model.
* Safety: This is a potentially dangerous job. If you are not comfortable with any of the steps, do not proceed.
This is a simplified overview. Again, refer to a repair manual for your specific vehicle before attempting this repair. If you're not confident in your abilities, have a qualified mechanic perform the brake work. Your safety and the safety of others depend on it.
