Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To secure the car.
* Socket wrench and sockets: Various sizes, likely including 13mm, 15mm, and possibly others.
* C-clamp or caliper compression tool: To compress the caliper piston. This is crucial.
* Pliers: For removing cotter pins (if applicable).
* Wrench for caliper bracket bolts (if applicable): Some models require removal of the caliper bracket.
* Brake cleaner: To clean the caliper and rotor.
* New brake pads: Make sure to get the correct pads for your Grand Am.
* Gloves: To protect your hands.
* Penetrating oil (like PB Blaster): May help loosen rusted bolts.
* Torque wrench: (Highly Recommended) To ensure proper tightening of bolts to prevent damage.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the rear wheels.
2. Raise and Secure the Vehicle: Use the jack to lift the front of the car and securely place it on jack stands.
3. Remove the Wheels: Use the lug wrench to remove the lug nuts and take off the wheels.
4. Expose the Brake Caliper: You should now see the brake caliper clamped around the rotor.
5. Compress the Caliper Piston: Using the C-clamp or caliper compression tool, carefully compress the caliper piston. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal. You may need to turn the piston slowly as you compress.
6. Remove the Brake Pads: There are typically two pads per caliper. They usually slide out with a little persuasion. You might need to use a screwdriver or pliers to help remove retaining clips if present.
7. Clean the Caliper and Rotor: Use brake cleaner to thoroughly clean the caliper piston, caliper slides, and rotor surface. Do not use compressed air. This can damage seals and other components. Allow everything to dry completely.
8. Install the New Brake Pads: Carefully insert the new brake pads into their respective locations. Ensure they are seated correctly.
9. Reinstall the Caliper: Carefully slide the caliper back over the rotor and the new pads.
10. Reinstall the Wheels: Tighten the lug nuts by hand, then use the lug wrench to tighten them securely in a star pattern (opposite nuts).
11. Lower the Vehicle: Carefully lower the vehicle using the jack.
12. Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer's specified torque. This is crucial to prevent wheel damage.
13. Test the Brakes: Before driving, pump the brake pedal several times to ensure proper engagement. Take the car for a short, careful test drive to verify the brakes are working properly.
14. Check for leaks and unusual noises.
Important Considerations:
* Rotor condition: Inspect the brake rotors for wear and scoring. If they're excessively worn or damaged, they'll need to be replaced or resurfaced.
* Caliper Condition: Check the caliper for leaks, sticking pistons, or any other signs of damage. A faulty caliper will require replacement.
* Brake fluid: This job doesn't usually require bleeding the brakes, but if you had to significantly work with the system, it's a good idea to consult a manual or professional for this step.
* Safety: Always prioritize safety. If you're not comfortable with any step, consult a mechanic. Improper brake maintenance can have serious consequences.
