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): You'll need various sizes.
* Wrench set (metric): For caliper bolts and brake line fittings (if applicable).
* C-clamp or brake caliper compressor tool: To compress the caliper piston.
* Brake cleaner: To clean brake parts.
* Penetrating lubricant (like PB Blaster): To help loosen rusted bolts.
* New brake pads: Make sure to get the correct pads for your Grand Am.
* New rotors (recommended): Often, you should replace rotors when replacing pads, especially if they're worn or scored.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Gloves: To keep your hands clean.
* Safety glasses: To protect your eyes.
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: Safely jack up the front of the car and securely place it on jack stands.
3. Remove the Wheels: Use your lug wrench to remove the lug nuts and take off the wheels.
4. Remove the Caliper:
* Locate the caliper bolts: These are usually on the back of the caliper.
* Apply penetrating lubricant: If the bolts are rusty or stuck.
* Remove the bolts: Carefully unscrew the caliper bolts and remove the caliper. Be prepared for some brake fluid to leak - it's a good idea to have some rags handy.
* Support the caliper: Use a wire or bungee cord to hang the caliper from the suspension; don't let it dangle by the brake line.
5. Remove the Brake Pads:
* The old brake pads should now be visible.
* Carefully remove the old brake pads. They may be held in place by clips or pins.
6. Remove and Replace the Rotors (if necessary):
* If you're replacing the rotors, remove the mounting bolts and carefully take off the old rotor.
* Install the new rotors.
7. Install New Brake Pads:
* Carefully install the new brake pads into their slots.
8. Compress the Caliper Piston: This is crucial. Use a C-clamp or a specialized brake caliper compressor tool to push the piston back into the caliper. You'll need to turn the piston slowly and steadily to avoid damage.
9. Install the Caliper: Carefully reinstall the caliper onto the mounting brackets. Tighten the bolts to the manufacturer's specified torque.
10. Reinstall the Wheels: Tighten the lug nuts in a star pattern to ensure even pressure. Don't overtighten.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer's specification.
13. Test the Brakes: Carefully test the brakes in a safe, open area. You should feel a firm pedal. If the pedal feels spongy, you might have air in the brake lines – this requires bleeding the brakes, which is a more advanced procedure.
Important Notes:
* Brake fluid is corrosive. Wear gloves and avoid getting it on your skin or paint.
* Always consult your vehicle's repair manual. This guide provides general steps, but your Grand Am might have specific differences.
* If you're unsure about any step, it's best to consult a professional mechanic. Improper brake repair can be dangerous.
* After installation, you may need to "bed in" your new brakes. This involves several gentle braking applications from higher speeds to properly seat the pads. Check your owner's manual or the brake pad packaging for instructions.
This information is for guidance only. Improper brake repair can be extremely dangerous. If you are not comfortable with this task, please take your vehicle to a qualified mechanic.
