Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheels.
* Socket wrench set (metric): With various sizes.
* C-clamp or brake caliper compression tool: To compress the caliper piston.
* Wrench for caliper bolts: Usually 14mm or 15mm.
* Wrench for brake line bleeder valve: Usually 8mm or 10mm.
* Pliers: For various tasks.
* Brake cleaner: To clean surfaces.
* New brake pads: Get the correct ones for your Grand Am. Parts stores can help you find the right fit.
* New rotors (optional but recommended): If the rotors are scored or worn, replace them.
* Gloves: To keep your hands clean.
* Shop rags or paper towels: For cleaning.
* Torque wrench (highly recommended): To tighten bolts to the correct specification.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Jack up the front of the car and securely place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Locate the caliper bolts (usually two) and loosen them with a wrench.
* Carefully remove the caliper. You may need to gently pry it away from the rotor. It's attached by a flexible brake line. Try to support the caliper's weight as you remove it to avoid stressing the brake line.
4. Compress the Caliper Piston: Use a C-clamp or caliper compression tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal. The piston may turn as you compress it.
5. Remove the Old Brake Pads: The old brake pads should slide right out.
6. Inspect the Rotors: Check the rotors for scoring, wear, or excessive rust. If they are excessively worn or damaged, replace them.
7. Install the New Brake Pads: Insert the new brake pads into the caliper brackets.
8. Reinstall the Caliper: Carefully slide the caliper back over the brake pads and rotor, ensuring the pads are properly seated. Reattach the caliper bolts and tighten them to the manufacturer's specified torque.
9. Repeat Steps 3-8 for the Other Wheel: Do the same for the other front wheel.
10. Bleed the Brakes (Crucial): After reinstalling the calipers, you *must* bleed the brakes to remove air from the brake lines. This is best done with a second person, but can be done solo with a pressure bleeder. Refer to your repair manual for the proper bleeding procedure. Improper bleeding can lead to spongy brakes or brake failure.
11. Lower the Vehicle: Carefully lower the vehicle.
12. Test the Brakes: Before driving, gently pump the brake pedal several times to ensure it feels firm. Test the brakes cautiously in a safe, open area before driving on the road.
Important Considerations:
* Repair Manual: A repair manual specific to your 1997 Pontiac Grand Am is highly recommended. It will provide detailed instructions, torque specifications, and diagrams.
* Brake Fluid: You may need to top off the brake fluid reservoir during the bleeding process. Use the correct type of brake fluid specified in your owner's manual.
* Safety: Always prioritize safety. If you're unsure about any step, seek professional help.
This guide provides a general overview. Improper brake work can lead to serious injury or death. If you are not comfortable performing this task, take your vehicle to a qualified mechanic.
