Here's a general overview. Specific steps and tools may vary slightly depending on the exact model and trim level of your Grand Am. Always consult your vehicle's repair manual for detailed instructions and torque specifications. This is just a guide, and I am not responsible for any damage you may cause.
Tools You'll Likely Need:
* Jack and jack stands (SAFETY FIRST: Never work under a car supported only by a jack.)
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Torque wrench
* Pliers or brake caliper pliers
* C-clamp or caliper compression tool
* Wire brush
* Brake cleaner
* New brake pads and rotors (if needed)
* Possibly a caliper rebuild kit (if needed)
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the car using the jack and securely place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* You'll likely need to use a socket wrench to remove the caliper mounting bolts. These are usually on the back of the caliper.
* Before completely removing the caliper, use a bungee cord or wire to hang it from something nearby to prevent it from dangling by the brake line. This relieves tension on the line. *Do not let the brake line hang freely*.
4. Remove the Brake Pads: The brake pads should slide out from the caliper. You may need to use pliers to gently pry them free.
5. Inspect the Rotors: Check the rotors for excessive wear, scoring, or damage. If they're worn, scored, or warped beyond specifications, they need to be replaced.
6. Install New Brake Pads: Install the new brake pads into the caliper.
7. Clean the Caliper: Clean the caliper piston and bore with a wire brush and brake cleaner.
8. Compress the Caliper Piston: Use a C-clamp or caliper compression tool to push the caliper piston back into the caliper. This is crucial to make room for the new, thicker brake pads. Be careful not to damage the piston seal.
9. Install the Caliper: Carefully install the caliper onto the mounting brackets.
10. Install the Rotor (if replaced): If you replaced the rotors, carefully install the new ones.
11. Reinstall the Wheel: Carefully replace the wheel and tighten the lug nuts to the manufacturer's specified torque. (Check your repair manual).
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Pump the Brakes: Pump the brake pedal several times to ensure the pads are properly seated.
14. Test Drive: Test drive the vehicle and check for any unusual noises or brake performance issues.
Important Considerations:
* Bleeding the Brakes: In most cases, you won't need to bleed the brakes after a simple pad replacement. However, if you've worked on the brake lines or caliper, bleeding may be necessary to remove air from the system.
* Caliper Rebuild: If the caliper piston is damaged or leaking, you may need to replace seals in the caliper. A caliper rebuild kit will help you do this.
* Torque Specifications: Always refer to your repair manual for proper torque specifications for all bolts and nuts.
* Safety: Working on your brakes is a safety-critical task. If you are not completely confident in your abilities, take your vehicle to a professional mechanic.
This is a simplified guide. Remember to consult your vehicle's repair manual for detailed, model-specific instructions. Improperly installed brakes can be extremely dangerous. If you're unsure about any step, seek professional help.
