Here's a general outline. Specifics may vary slightly depending on your exact Malibu model and trim. Consult a repair manual specific to your 2003 Malibu for detailed instructions and torque specifications. This information is for guidance only and I am not responsible for any damage or injury.
Tools You'll Need:
* Jack and jack stands: Essential for safe lifting. Never work under a car supported only by a jack.
* Wheel chocks: For added safety.
* Lug wrench: To remove the wheels.
* Socket wrench set (metric): Various sizes will be needed.
* C-clamp or brake caliper compression tool: To compress the caliper piston. A C-clamp works, but a specialized tool is easier and less likely to damage the piston.
* Penetrating oil (like PB Blaster): To loosen rusted bolts.
* Wrench or socket for caliper bracket bolts: Size will vary.
* Clean rags or shop towels: To clean up brake dust and fluid.
* New brake pads: Make sure you get the correct pads for your Malibu.
* Safety glasses: Protect your eyes from flying debris.
* Gloves: Protect your hands from brake dust and grease.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels that remain on the ground.
2. Jack Up and Secure: Jack up the front of the car and securely place it on jack stands.
3. Remove Wheel: Remove the lug nuts and take off the wheel.
4. Expose Caliper: You should now see the brake caliper, brake rotor, and brake pads.
5. Compress Caliper Piston: Using the C-clamp or 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 slightly as you compress it.
6. Remove Caliper: Remove the bolts holding the caliper bracket to the caliper. These bolts are usually on the back of the caliper. Carefully remove the caliper and support it with a wire or bungee cord to prevent it from hanging by the brake line.
7. Remove Old Brake Pads: The old brake pads should now be easily removable. You may need to gently pry them out.
8. Install New Brake Pads: Install the new brake pads into the caliper bracket.
9. Reinstall Caliper: Carefully reinstall the caliper and attach it with its bolts.
10. Reinstall Wheel: Reinstall the wheel and tighten the lug nuts. Do not overtighten.
11. Repeat: Repeat steps 3-10 for the other front wheel.
12. Lower Vehicle: Carefully lower the vehicle.
13. Check and Test: Check that the lug nuts are snug, and carefully pump the brake pedal several times to ensure the brakes engage properly. Test drive the car to verify braking performance. If anything feels unusual, take it to a mechanic immediately.
Important Considerations:
* Brake Fluid: While you're not directly working with brake fluid, you might need to top it off later if the piston was extended excessively.
* Rotor Condition: Inspect the brake rotors for wear and tear. If they're excessively worn or grooved, they'll need to be replaced or turned (machined).
* Caliper Condition: Inspect the calipers for leaks, sticking pistons, or damage. Repair or replace them as needed.
This is a simplified explanation. Again, refer to a repair manual for your specific 2003 Chevy Malibu model. Working on brakes is a safety-critical task; if you're unsure about any step, seek professional help.
