This is a general guide, and specific steps may vary slightly depending on your exact Malibu model. Always consult your owner's manual for specific torque specifications and safety information.
Tools You'll Need:
* Jack and jack stands (Crucial for safety)
* Wheel chocks
* Lug wrench
* Socket wrench with appropriate sockets (likely 13mm, 14mm, and 15mm, but check your manual)
* C-clamp or brake caliper compressor tool
* Wire brush or brake cleaner
* Brake pad shims (if necessary)
* New brake pads
* New brake rotors
* Penetrating oil (like PB Blaster)
* Torque wrench (essential for proper tightening)
* Gloves
* Safety glasses
Steps:
1. Preparation:
* Safety First: Park on a level surface, engage the parking brake, and chock the wheels opposite the one you're working on. This is absolutely crucial to prevent the car from rolling.
* Raise the Vehicle: Securely jack up the vehicle and place it on jack stands under the frame near the wheel you are working on. Never work under a vehicle supported only by a jack.
2. Remove the Wheel:
* Use your lug wrench to loosen the lug nuts slightly. Don't remove them completely yet.
* Raise the car fully.
* Remove the lug nuts completely and carefully remove the wheel.
3. Remove the Caliper:
* Use the appropriate socket to remove the caliper mounting bolts. Penetrating oil can help if they're stuck.
* Carefully remove the caliper. You might need to gently pry it away from the rotor. Support the caliper with a bungee cord or wire to prevent it from hanging by the brake line. This protects the brake line from damage.
4. Remove the Brake Pads:
* The old brake pads should now be visible. Remove them. Note their orientation (sometimes there are wear indicators on the pads).
5. Remove the Rotor:
* Depending on your model, you may need to remove a caliper bracket bolt or two additional bolts to access the rotor. Sometimes the rotor just slides off after removing the caliper and pads, and others it's held on by small bolts. Consult your repair manual!
* Clean the rotor mounting hub with a wire brush.
6. Install the New Rotor:
* Install the new rotor onto the wheel hub. Ensure it's properly seated and clean.
7. Install the New Brake Pads:
* Carefully install the new brake pads, making sure they are correctly oriented. Use the shims if provided.
8. Install the Caliper:
* Carefully reinstall the caliper. Ensure the caliper slides smoothly in its bracket.
9. Reinstall the Wheel:
* Install the wheel and tighten the lug nuts hand-tight. Lower the car to the ground using the jack.
10. Final Tightening:
* Use the lug wrench to tighten the lug nuts in a star pattern (opposite nuts, then the ones in between) to ensure even pressure. Use your torque wrench to tighten the lug nuts to the manufacturer's specified torque.
11. Bleed the Brakes (If Necessary):
* Sometimes, you may need to bleed the brakes after replacing components. This removes air bubbles from the brake lines. If the brake pedal feels spongy after reassembly, it's essential to bleed the brakes. Look up the procedure for bleeding your car's brakes.
Important Considerations:
* Repair Manual: A repair manual specific to your 2005 Chevy Malibu is highly recommended. It will provide detailed diagrams and torque specifications.
* Safety: Always prioritize safety. Never work under a car supported only by a jack.
* Parts Quality: Use high-quality brake pads and rotors from a reputable brand.
* Brake Fluid: If you need to bleed your brakes, be sure to use the correct type of brake fluid.
This is a simplified overview. Incorrect installation can lead to brake failure, which is extremely dangerous. If you are unsure about any step, consult a professional mechanic. It's better to be safe than sorry.
